Hi all, On behalf of the SciPy development team I'm pleased to announce the release of SciPy 1.7.0. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.7.0 One of a few ways to install this release with pip: pip install scipy==1.7.0 ===================== SciPy 1.7.0 Release Notes ===================== SciPy 1.7.0 is the culmination of 6 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Before upgrading, we recommend that users check that their own code does not use deprecated SciPy functionality (to do so, run your code with ``python -Wd`` and check for ``DeprecationWarning`` s). Our development attention will now shift to bug-fix releases on the 1.7.x branch, and on adding new features on the master branch. This release requires Python 3.7+ and NumPy 1.16.5 or greater. For running on PyPy, PyPy3 6.0+ is required. **************************** Highlights of this release **************************** - A new submodule for quasi-Monte Carlo, `scipy.stats.qmc`, was added - The documentation design was updated to use the same PyData-Sphinx theme as NumPy and other ecosystem libraries. - We now vendor and leverage the Boost C++ library to enable numerous improvements for long-standing weaknesses in `scipy.stats` - `scipy.stats` has six new distributions, eight new (or overhauled) hypothesis tests, a new function for bootstrapping, a class that enables fast random variate sampling and percentile point function evaluation, and many other enhancements. - ``cdist`` and ``pdist`` distance calculations are faster for several metrics, especially weighted cases, thanks to a rewrite to a new C++ backend framework - A new class for radial basis function interpolation, `RBFInterpolator`, was added to address issues with the `Rbf` class. We gratefully acknowledge the Chan-Zuckerberg Initiative Essential Open Source Software for Science program for supporting many of the improvements to `scipy.stats`. *************** New features *************** `scipy.cluster` improvements ====================== An optional argument, ``seed``, has been added to ``kmeans`` and ``kmeans2`` to set the random generator and random state. `scipy.interpolate` improvements ========================= Improved input validation and error messages for ``fitpack.bispev`` and ``fitpack.parder`` for scenarios that previously caused substantial confusion for users. The class `RBFInterpolator` was added to supersede the `Rbf` class. The new class has usage that more closely follows other interpolator classes, corrects sign errors that caused unexpected smoothing behavior, includes polynomial terms in the interpolant (which are necessary for some RBF choices), and supports interpolation using only the k-nearest neighbors for memory efficiency. `scipy.linalg` improvements ===================== An LAPACK wrapper was added for access to the ``tgexc`` subroutine. `scipy.ndimage` improvements ======================= `scipy.ndimage.affine_transform` is now able to infer the ``output_shape`` from the ``out`` array. `scipy.optimize` improvements ======================= The optional parameter ``bounds`` was added to ``_minimize_neldermead`` to support bounds constraints for the Nelder-Mead solver. ``trustregion`` methods ``trust-krylov``, ``dogleg`` and ``trust-ncg`` can now estimate ``hess`` by finite difference using one of ``["2-point", "3-point", "cs"]``. ``halton`` was added as a ``sampling_method`` in `scipy.optimize.shgo`. ``sobol`` was fixed and is now using `scipy.stats.qmc.Sobol`. ``halton`` and ``sobol`` were added as ``init`` methods in `scipy.optimize.differential_evolution.` ``differential_evolution`` now accepts an ``x0`` parameter to provide an initial guess for the minimization. ``least_squares`` has a modest performance improvement when SciPy is built with Pythran transpiler enabled. When ``linprog`` is used with ``method`` ``'highs'``, ``'highs-ipm'``, or ``'highs-ds'``, the result object now reports the marginals (AKA shadow prices, dual values) and residuals associated with each constraint. `scipy.signal` improvements ===================== ``get_window`` supports ``general_cosine`` and ``general_hamming`` window functions. `scipy.signal.medfilt2d` now releases the GIL where appropriate to enable performance gains via multithreaded calculations. `scipy.sparse` improvements ====================== Addition of ``dia_matrix`` sparse matrices is now faster. `scipy.spatial` improvements ====================== ``distance.cdist`` and ``distance.pdist`` performance has greatly improved for certain weighted metrics. Namely: ``minkowski``, ``euclidean``, ``chebyshev``, ``canberra``, and ``cityblock``. Modest performance improvements for many of the unweighted ``cdist`` and ``pdist`` metrics noted above. The parameter ``seed`` was added to `scipy.spatial.vq.kmeans` and `scipy.spatial.vq.kmeans2`. The parameters ``axis`` and ``keepdims`` where added to `scipy.spatial.distance.jensenshannon`. The ``rotation`` methods ``from_rotvec`` and ``as_rotvec`` now accept a ``degrees`` argument to specify usage of degrees instead of radians. `scipy.special` improvements ====================== Wright's generalized Bessel function for positive arguments was added as `scipy.special.wright_bessel.` An implementation of the inverse of the Log CDF of the Normal Distribution is now available via `scipy.special.ndtri_exp`. `scipy.stats` improvements ==================== Hypothesis Tests ----------------------- The Mann-Whitney-Wilcoxon test, ``mannwhitneyu``, has been rewritten. It now supports n-dimensional input, an exact test method when there are no ties, and improved documentation. Please see "Other changes" for adjustments to default behavior. The new function `scipy.stats.binomtest` replaces `scipy.stats.binom_test`. The new function returns an object that calculates a confidence intervals of the proportion parameter. Also, performance was improved from O(n) to O(log(n)) by using binary search. The two-sample version of the Cramer-von Mises test is implemented in `scipy.stats.cramervonmises_2samp`. The Alexander-Govern test is implemented in the new function `scipy.stats.alexandergovern`. The new functions `scipy.stats.barnard_exact` and `scipy.stats. boschloo_exact` respectively perform Barnard's exact test and Boschloo's exact test for 2x2 contingency tables. The new function `scipy.stats.page_trend_test` performs Page's test for ordered alternatives. The new function `scipy.stats.somersd` performs Somers' D test for ordinal association between two variables. An option, ``permutations``, has been added in `scipy.stats.ttest_ind` to perform permutation t-tests. A ``trim`` option was also added to perform a trimmed (Yuen's) t-test. The ``alternative`` parameter was added to the ``skewtest``, ``kurtosistest``, ``ranksums``, ``mood``, ``ansari``, ``linregress``, and ``spearmanr`` functions to allow one-sided hypothesis testing. Sample statistics ----------------------- The new function `scipy.stats.differential_entropy` estimates the differential entropy of a continuous distribution from a sample. The ``boxcox`` and ``boxcox_normmax`` now allow the user to control the optimizer used to minimize the negative log-likelihood function. A new function `scipy.stats.contingency.relative_risk` calculates the relative risk, or risk ratio, of a 2x2 contingency table. The object returned has a method to compute the confidence interval of the relative risk. Performance improvements in the ``skew`` and ``kurtosis`` functions achieved by removal of repeated/redundant calculations. Substantial performance improvements in `scipy.stats.mstats.hdquantiles_sd`. The new function `scipy.stats.contingency.association` computes several measures of association for a contingency table: Pearsons contingency coefficient, Cramer's V, and Tschuprow's T. The parameter ``nan_policy`` was added to `scipy.stats.zmap` to provide options for handling the occurrence of ``nan`` in the input data. The parameter ``ddof`` was added to `scipy.stats.variation` and `scipy.stats.mstats.variation`. The parameter ``weights`` was added to `scipy.stats.gmean`. Statistical Distributions ------------------------------- We now vendor and leverage the Boost C++ library to address a number of previously reported issues in ``stats``. Notably, ``beta``, ``binom``, ``nbinom`` now have Boost backends, and it is straightforward to leverage the backend for additional functions. The skew Cauchy probability distribution has been implemented as `scipy.stats.skewcauchy`. The Zipfian probability distribution has been implemented as `scipy.stats.zipfian`. The new distributions ``nchypergeom_fisher`` and ``nchypergeom_wallenius`` implement the Fisher and Wallenius versions of the noncentral hypergeometric distribution, respectively. The generalized hyperbolic distribution was added in `scipy.stats.genhyperbolic`. The studentized range distribution was added in `scipy.stats.studentized_range`. `scipy.stats.argus` now has improved handling for small parameter values. Better argument handling/preparation has resulted in performance improvements for many distributions. The ``cosine`` distribution has added ufuncs for ``ppf``, ``cdf``, ``sf``, and ``isf`` methods including numerical precision improvements at the edges of the support of the distribution. An option to fit the distribution to data by the method of moments has been added to the ``fit`` method of the univariate continuous distributions. Other --------- `scipy.stats.bootstrap` has been added to allow estimation of the confidence interval and standard error of a statistic. The new function `scipy.stats.contingency.crosstab` computes a contingency table (i.e. a table of counts of unique entries) for the given data. `scipy.stats.NumericalInverseHermite` enables fast random variate sampling and percentile point function evaluation of an arbitrary univariate statistical distribution. New `scipy.stats.qmc` module ----------------------------------------- This new module provides Quasi-Monte Carlo (QMC) generators and associated helper functions. It provides a generic class `scipy.stats.qmc.QMCEngine` which defines a QMC engine/sampler. An engine is state aware: it can be continued, advanced and reset. 3 base samplers are available: - `scipy.stats.qmc.Sobol` the well known Sobol low discrepancy sequence. Several warnings have been added to guide the user into properly using this sampler. The sequence is scrambled by default. - `scipy.stats.qmc.Halton`: Halton low discrepancy sequence. The sequence is scrambled by default. - `scipy.stats.qmc.LatinHypercube`: plain LHS design. And 2 special samplers are available: - `scipy.stats.qmc.MultinomialQMC`: sampling from a multinomial distribution using any of the base `scipy.stats.qmc.QMCEngine`. - `scipy.stats.qmc.MultivariateNormalQMC`: sampling from a multivariate Normal using any of the base `scipy.stats.qmc.QMCEngine`. The module also provide the following helpers: - `scipy.stats.qmc.discrepancy`: assess the quality of a set of points in terms of space coverage. - `scipy.stats.qmc.update_discrepancy`: can be used in an optimization loop to construct a good set of points. - `scipy.stats.qmc.scale`: easily scale a set of points from (to) the unit interval to (from) a given range. *********************** Deprecated features *********************** `scipy.linalg` deprecations ==================== - `scipy.linalg.pinv2` is deprecated and its functionality is completely subsumed into `scipy.linalg.pinv` - Both ``rcond``, ``cond`` keywords of `scipy.linalg.pinv` and `scipy.linalg.pinvh` were not working and now are deprecated. They are now replaced with functioning ``atol`` and ``rtol`` keywords with clear usage. `scipy.spatial` deprecations ===================== - `scipy.spatial.distance` metrics expect 1d input vectors but will call ``np.squeeze`` on their inputs to accept any extra length-1 dimensions. That behaviour is now deprecated. ***************** Other changes ***************** We now accept and leverage performance improvements from the ahead-of-time Python-to-C++ transpiler, Pythran, which can be optionally disabled (via ``export SCIPY_USE_PYTHRAN=0``) but is enabled by default at build time. There are two changes to the default behavior of `scipy.stats.mannwhitenyu`: - For years, use of the default ``alternative=None`` was deprecated; explicit ``alternative`` specification was required. Use of the new default value of ``alternative``, "two-sided", is now permitted. - Previously, all p-values were based on an asymptotic approximation. Now, for small samples without ties, the p-values returned are exact by default. Support has been added for PEP 621 (project metadata in ``pyproject.toml``) We now support a Gitpod environment to reduce the barrier to entry for SciPy development; for more details see :ref:`quickstart-gitpod`. ********* Authors ********* * @endolith * Jelle Aalbers + * Adam + * Tania Allard + * Sven Baars + * Max Balandat + * baumgarc + * Christoph Baumgarten * Peter Bell * Lilian Besson * Robinson Besson + * Max Bolingbroke * Blair Bonnett + * Jordão Bragantini * Harm Buisman + * Evgeni Burovski * Matthias Bussonnier * Dominic C * CJ Carey * Ramón Casero + * Chachay + * charlotte12l + * Benjamin Curtice Corbett + * Falcon Dai + * Ian Dall + * Terry Davis * droussea2001 + * DWesl + * dwight200 + * Thomas J.

A proposal on adding new TFQMR algorithm
by 赵刚 June 20, 2021

June 20, 2021

Dear all, I have submitted an python implementation of the sparse linear iterative algorithm "Transpose-Free QMR" (https://github.com/scipy/scipy/pull/14160). This algorithm (cited by 904) is very effective to solve non-Hermitian linear systems because it has a smoother convergence curve than the other algorithms like CGS, Bi-CGSTAB, and it has been widely used in those prominent scientific computing packages such as PETSc etc. The purpose of adding the algorithm is to enrich SciPy's sparse linear library, so that users can have more/better choices when using Krylov subspace methods in SciPy to solve linear systems. I also hope that experts in this field can review the implementation of the algorithm (References are listed in "tfqmr.py"). Hope you like it. Thanks, Gang

PR: addition of Tukey's HSD test
by Sam Wallan June 17, 2021

June 17, 2021

Hello All, The PR gh-13002 <https://github.com/scipy/scipy/pull/13002> implements Tukey’s Honestly Significant Difference Test, a multiple sample test used to find pairs of means that are significantly different from each other. We’d appreciate your thoughts! The test reports the pairwise differences, p-values, and confidence intervals in separate attribute arrays of shape (n, n). This allows the client to access their desired results programmatically, which is not nearly as easy in other programs. There are a few areas with which extra input would be helpful. Specifically: - output interface - __str__ / __repr__ methods - confidence interval method More details are in the PR. Many thanks, Sam

ANN: SciPy 1.7.0rc2 -- please test
by Tyler Reddy June 14, 2021

June 14, 2021

Hi all, On behalf of the SciPy development team I'm pleased to announce the release candidate SciPy 1.7.0rc2. Please help us test this pre-release, which notably no longer includes Cython- generated C source files in the sdist. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.7.0rc2 <https://github.com/scipy/scipy/releases/tag/v1.7.0rc1> One of a few ways to install the release candidate with pip: pip install scipy==1.7.0rc2 ===================== SciPy 1.7.0 Release Notes ===================== Note: Scipy 1.7.0 is not released yet! SciPy 1.7.0 is the culmination of 6 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Before upgrading, we recommend that users check that their own code does not use deprecated SciPy functionality (to do so, run your code with ``python -Wd`` and check for ``DeprecationWarning`` s). Our development attention will now shift to bug-fix releases on the 1.7.x branch, and on adding new features on the master branch. This release requires Python 3.7+ and NumPy 1.16.5 or greater. For running on PyPy, PyPy3 6.0+ is required. **************************** Highlights of this release **************************** - A new submodule for quasi-Monte Carlo, `scipy.stats.qmc`, was added - The documentation design was updated to use the same PyData-Sphinx theme as other NumFOCUS packages like NumPy. - We now vendor and leverage the Boost C++ library to enable numerous improvements for long-standing weaknesses in `scipy.stats` - `scipy.stats` has six new distributions, eight new (or overhauled) hypothesis tests, a new function for bootstrapping, a class that enables fast random variate sampling and percentile point function evaluation, and many other enhancements. - ``cdist`` and ``pdist`` distance calculations are faster for several metrics, especially weighted cases, thanks to a rewrite to a new C++ backend framework - A new class for radial basis function interpolation, `RBFInterpolator`, was added to address issues with the `Rbf` class. We gratefully acknowledge the Chan-Zuckerberg Initiative Essential Open Source Software for Science program for supporting many of the improvements to `scipy.stats`. *************** New features *************** `scipy.cluster` improvements ====================== An optional argument, ``seed``, has been added to ``kmeans`` and ``kmeans2`` to set the random generator and random state. `scipy.interpolate` improvements ========================= Improved input validation and error messages for ``fitpack.bispev`` and ``fitpack.parder`` for scenarios that previously caused substantial confusion for users. The class `RBFInterpolator` was added to supersede the `Rbf` class. The new class has usage that more closely follows other interpolator classes, corrects sign errors that caused unexpected smoothing behavior, includes polynomial terms in the interpolant (which are necessary for some RBF choices), and supports interpolation using only the k-nearest neighbors for memory efficiency. `scipy.linalg` improvements ===================== An LAPACK wrapper was added for access to the ``tgexc`` subroutine. `scipy.ndimage` improvements ======================== `scipy.ndimage.affine_transform` is now able to infer the ``output_shape`` from the ``out`` array. `scipy.optimize` improvements ======================= The optional parameter ``bounds`` was added to ``_minimize_neldermead`` to support bounds constraints for the Nelder-Mead solver. ``trustregion`` methods ``trust-krylov``, ``dogleg`` and ``trust-ncg`` can now estimate ``hess`` by finite difference using one of ``["2-point", "3-point", "cs"]``. ``halton`` was added as a ``sampling_method`` in `scipy.optimize.shgo`. ``sobol`` was fixed and is now using `scipy.stats.qmc.Sobol`. ``halton`` and ``sobol`` were added as ``init`` methods in `scipy.optimize.differential_evolution.` ``differential_evolution`` now accepts an ``x0`` parameter to provide an initial guess for the minimization. ``least_squares`` has a modest performance improvement when SciPy is built with Pythran transpiler enabled. When ``linprog`` is used with ``method`` ``'highs'``, ``'highs-ipm'``, or ``'highs-ds'``, the result object now reports the marginals (AKA shadow prices, dual values) and residuals associated with each constraint. `scipy.signal` improvements ====================== ``get_window`` supports ``general_cosine`` and ``general_hamming`` window functions. `scipy.signal.medfilt2d` now releases the GIL where appropriate to enable performance gains via multithreaded calculations. `scipy.sparse` improvements ====================== Addition of ``dia_matrix`` sparse matrices is now faster. `scipy.spatial` improvements ====================== ``distance.cdist`` and ``distance.pdist`` performance has greatly improved for certain weighted metrics. Namely: ``minkowski``, ``euclidean``, ``chebyshev``, ``canberra``, and ``cityblock``. Modest performance improvements for many of the unweighted ``cdist`` and ``pdist`` metrics noted above. The parameter ``seed`` was added to `scipy.spatial.vq.kmeans` and `scipy.spatial.vq.kmeans2`. The parameters ``axis`` and ``keepdims`` where added to `scipy.spatial.distance.jensenshannon`. The ``rotation`` methods ``from_rotvec`` and ``as_rotvec`` now accept a ``degrees`` argument to specify usage of degrees instead of radians. `scipy.special` improvements ====================== Wright's generalized Bessel function for positive arguments was added as `scipy.special.wright_bessel.` An implementation of the inverse of the Log CDF of the Normal Distribution is now available via `scipy.special.ndtri_exp`. `scipy.stats` improvements ==================== Hypothesis Tests ------------------------ The Mann-Whitney-Wilcoxon test, ``mannwhitneyu``, has been rewritten. It now supports n-dimensional input, an exact test method when there are no ties, and improved documentation. Please see "Other changes" for adjustments to default behavior. The new function `scipy.stats.binomtest` replaces `scipy.stats.binom_test`. The new function returns an object that calculates a confidence intervals of the proportion parameter. Also, performance was improved from O(n) to O(log(n)) by using binary search. The two-sample version of the Cramer-von Mises test is implemented in `scipy.stats.cramervonmises_2samp`. The Alexander-Govern test is implemented in the new function `scipy.stats.alexandergovern`. The new functions `scipy.stats.barnard_exact` and `scipy.stats. boschloo_exact` respectively perform Barnard's exact test and Boschloo's exact test for 2x2 contingency tables. The new function `scipy.stats.page_trend_test` performs Page's test for ordered alternatives. The new function `scipy.stats.somersd` performs Somers' D test for ordinal association between two variables. An option, ``permutations``, has been added in `scipy.stats.ttest_ind` to perform permutation t-tests. A ``trim`` option was also added to perform a trimmed (Yuen's) t-test. The ``alternative`` parameter was added to the ``skewtest``, ``kurtosistest``, ``ranksums``, ``mood``, ``ansari``, ``linregress``, and ``spearmanr`` functions to allow one-sided hypothesis testing. Sample statistics ----------------------- The new function `scipy.stats.differential_entropy` estimates the differential entropy of a continuous distribution from a sample. The ``boxcox`` and ``boxcox_normmax`` now allow the user to control the optimizer used to minimize the negative log-likelihood function. A new function `scipy.stats.contingency.relative_risk` calculates the relative risk, or risk ratio, of a 2x2 contingency table. The object returned has a method to compute the confidence interval of the relative risk. Performance improvements in the ``skew`` and ``kurtosis`` functions achieved by removal of repeated/redundant calculations. Substantial performance improvements in `scipy.stats.mstats.hdquantiles_sd`. The new function `scipy.stats.contingency.association` computes several measures of association for a contingency table: Pearsons contingency coefficient, Cramer's V, and Tschuprow's T. The parameter ``nan_policy`` was added to `scipy.stats.zmap` to provide options for handling the occurrence of ``nan`` in the input data. The parameter ``ddof`` was added to `scipy.stats.variation` and `scipy.stats.mstats.variation`. The parameter ``weights`` was added to `scipy.stats.gmean`. Statistical Distributions ------------------------------- We now vendor and leverage the Boost C++ library to address a number of previously reported issues in ``stats``. Notably, ``beta``, ``binom``, ``nbinom`` now have Boost backends, and it is straightforward to leverage the backend for additional functions. The skew Cauchy probability distribution has been implemented as `scipy.stats.skewcauchy`. The Zipfian probability distribution has been implemented as `scipy.stats.zipfian`. The new distributions ``nchypergeom_fisher`` and ``nchypergeom_wallenius`` implement the Fisher and Wallenius versions of the noncentral hypergeometric distribution, respectively. The generalized hyperbolic distribution was added in `scipy.stats.genhyperbolic`. The studentized range distribution was added in `scipy.stats.studentized_range`. `scipy.stats.argus` now has improved handling for small parameter values. Better argument handling/preparation has resulted in performance improvements for many distributions. The ``cosine`` distribution has added ufuncs for ``ppf``, ``cdf``, ``sf``, and ``isf`` methods including numerical precision improvements at the edges of the support of the distribution. An option to fit the distribution to data by the method of moments has been added to the ``fit`` method of the univariate continuous distributions. Other -------- `scipy.stats.bootstrap` has been added to allow estimation of the confidence interval and standard error of a statistic. The new function `scipy.stats.contingency.crosstab` computes a contingency table (i.e. a table of counts of unique entries) for the given data. `scipy.stats.NumericalInverseHermite` enables fast random variate sampling and percentile point function evaluation of an arbitrary univariate statistical distribution. New `scipy.stats.qmc` module ----------------------------------------- This new module provides Quasi-Monte Carlo (QMC) generators and associated helper functions. It provides a generic class `scipy.stats.qmc.QMCEngine` which defines a QMC engine/sampler. An engine is state aware: it can be continued, advanced and reset. 3 base samplers are available: - `scipy.stats.qmc.Sobol` the well known Sobol low discrepancy sequence. Several warnings have been added to guide the user into properly using this sampler. The sequence is scrambled by default. - `scipy.stats.qmc.Halton`: Halton low discrepancy sequence. The sequence is scrambled by default. - `scipy.stats.qmc.LatinHypercube`: plain LHS design. And 2 special samplers are available: - `scipy.stats.qmc.MultinomialQMC`: sampling from a multinomial distribution using any of the base `scipy.stats.qmc.QMCEngine`. - `scipy.stats.qmc.MultivariateNormalQMC`: sampling from a multivariate Normal using any of the base `scipy.stats.qmc.QMCEngine`. The module also provide the following helpers: - `scipy.stats.qmc.discrepancy`: assess the quality of a set of points in terms of space coverage. - `scipy.stats.qmc.update_discrepancy`: can be used in an optimization loop to construct a good set of points. - `scipy.stats.qmc.scale`: easily scale a set of points from (to) the unit interval to (from) a given range. ************************ Deprecated features ************************ `scipy.linalg` deprecations ==================== - `scipy.linalg.pinv2` is deprecated and its functionality is completely subsumed into `scipy.linalg.pinv` - Both ``rcond``, ``cond`` keywords of `scipy.linalg.pinv` and `scipy.linalg.pinvh` were not working and now are deprecated. They are now replaced with functioning ``atol`` and ``rtol`` keywords with clear usage. `scipy.spatial` deprecations ===================== - `scipy.spatial.distance` metrics expect 1d input vectors but will call ``np.squeeze`` on their inputs to accept any extra length-1 dimensions. That behaviour is now deprecated. ****************** Other changes ****************** We now accept and leverage performance improvements from the ahead-of-time Python-to-C++ transpiler, Pythran, which can be optionally disabled (via ``export SCIPY_USE_PYTHRAN=0``) but is enabled by default at build time. There are two changes to the default behavior of `scipy.stats.mannwhitenyu`: - For years, use of the default ``alternative=None`` was deprecated; explicit ``alternative`` specification was required. Use of the new default value of ``alternative``, "two-sided", is now permitted. - Previously, all p-values were based on an asymptotic approximation. Now, for small samples without ties, the p-values returned are exact by default. Support has been added for PEP 621 (project metadata in ``pyproject.toml``) We now support a Gitpod environment to reduce the barrier to entry for SciPy development; for more details see :ref:`quickstart-gitpod`. ********* Authors ********* * @endolith * Jelle Aalbers + * Adam + * Tania Allard + * Sven Baars + * Max Balandat + * baumgarc + * Christoph Baumgarten * Peter Bell * Lilian Besson * Robinson Besson + * Max Bolingbroke * Blair Bonnett + * Jordão Bragantini * Harm Buisman + * Evgeni Burovski * Matthias Bussonnier * Dominic C * CJ Carey * Ramón Casero + * Chachay + * charlotte12l + * Benjamin Curtice Corbett + * Falcon Dai + * Ian Dall + * Terry Davis * droussea2001 + * DWesl + * dwight200 + * Thomas J.

Adding Wigner-Ville distribution and related methods to scipy.signal
by Leander Claes June 14, 2021

June 14, 2021

Dear SciPy developers, I recently submitted a pull request to add the Wigner-Ville distribution (wvd) to scipy.signal (https://github.com/scipy/scipy/pull/14141). To oversimplify the description of the wvd: It is a method for time-frequency analysis similar to the short-time Fourier-transform or the wavelet transform with some really interesting properties that makes it useful in many applications (e.g. detecting gravitational waves). We often use it in our group and we teach it to students in our lecture on signal processing with python. It was kindly suggested that I send a mail to this list first to check if there was need for such a function. So here I am: Do you think that Wigner-Ville distribution (and maybe later some the derived methods) should be added scipy? Thank you for the consideration. Best regards, Leander (lndr)

ANN: SciPy 1.7.0rc1 -- please test
by Tyler Reddy June 9, 2021

June 9, 2021

Hi all, On behalf of the SciPy development team I'm pleased to announce the release candidate SciPy 1.7.0rc1. Please help us test this pre-release. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.7.0rc1 One of a few ways to install the release candidate with pip: pip install scipy==1.7.0rc1 ===================== SciPy 1.7.0 Release Notes ===================== Note: Scipy 1.7.0 is not released yet! SciPy 1.7.0 is the culmination of 6 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Before upgrading, we recommend that users check that their own code does not use deprecated SciPy functionality (to do so, run your code with ``python -Wd`` and check for ``DeprecationWarning`` s). Our development attention will now shift to bug-fix releases on the 1.7.x branch, and on adding new features on the master branch. This release requires Python 3.7+ and NumPy 1.16.5 or greater. For running on PyPy, PyPy3 6.0+ is required. **************************** Highlights of this release **************************** - A new submodule for quasi-Monte Carlo, `scipy.stats.qmc`, was added - The documentation design was updated to use the same PyData-Sphinx theme as other NumFOCUS packages like NumPy. - We now vendor and leverage the Boost C++ library to enable numerous improvements for long-standing weaknesses in `scipy.stats` - `scipy.stats` has six new distributions, eight new (or overhauled) hypothesis tests, a new function for bootstrapping, a class that enables fast random variate sampling and percentile point function evaluation, and many other enhancements. - ``cdist`` and ``pdist`` distance calculations are faster for several metrics, especially weighted cases, thanks to a rewrite to a new C++ backend framework - A new class for radial basis function interpolation, `RBFInterpolator`, was added to address issues with the `Rbf` class. We gratefully acknowledge the Chan-Zuckerberg Initiative Essential Open Source Software for Science program for supporting many of the improvements to `scipy.stats`. *************** New features *************** `scipy.cluster` improvements ====================== An optional argument, ``seed``, has been added to ``kmeans`` and ``kmeans2`` to set the random generator and random state. `scipy.interpolate` improvements ========================= Improved input validation and error messages for ``fitpack.bispev`` and ``fitpack.parder`` for scenarios that previously caused substantial confusion for users. The class `RBFInterpolator` was added to supersede the `Rbf` class. The new class has usage that more closely follows other interpolator classes, corrects sign errors that caused unexpected smoothing behavior, includes polynomial terms in the interpolant (which are necessary for some RBF choices), and supports interpolation using only the k-nearest neighbors for memory efficiency. `scipy.linalg` improvements ===================== An LAPACK wrapper was added for access to the ``tgexc`` subroutine. `scipy.ndimage` improvements ======================= `scipy.ndimage.affine_transform` is now able to infer the ``output_shape`` from the ``out`` array. `scipy.optimize` improvements ======================= The optional parameter ``bounds`` was added to ``_minimize_neldermead`` to support bounds constraints for the Nelder-Mead solver. ``trustregion`` methods ``trust-krylov``, ``dogleg`` and ``trust-ncg`` can now estimate ``hess`` by finite difference using one of ``["2-point", "3-point", "cs"]``. ``halton`` was added as a ``sampling_method`` in `scipy.optimize.shgo`. ``sobol`` was fixed and is now using `scipy.stats.qmc.Sobol`. ``halton`` and ``sobol`` were added as ``init`` methods in `scipy.optimize.differential_evolution.` ``differential_evolution`` now accepts an ``x0`` parameter to provide an initial guess for the minimization. ``least_squares`` has a modest performance improvement when SciPy is built with Pythran transpiler enabled. When ``linprog`` is used with ``method`` ``'highs'``, ``'highs-ipm'``, or ``'highs-ds'``, the result object now reports the marginals (AKA shadow prices, dual values) and residuals associated with each constraint. `scipy.signal` improvements ===================== ``get_window`` supports ``general_cosine`` and ``general_hamming`` window functions. `scipy.signal.medfilt2d` now releases the GIL where appropriate to enable performance gains via multithreaded calculations. `scipy.sparse` improvements ====================== Addition of ``dia_matrix`` sparse matrices is now faster. `scipy.spatial` improvements ====================== ``distance.cdist`` and ``distance.pdist`` performance has greatly improved for certain weighted metrics. Namely: ``minkowski``, ``euclidean``, ``chebyshev``, ``canberra``, and ``cityblock``. Modest performance improvements for many of the unweighted ``cdist`` and ``pdist`` metrics noted above. The parameter ``seed`` was added to `scipy.spatial.vq.kmeans` and `scipy.spatial.vq.kmeans2`. The parameters ``axis`` and ``keepdims`` where added to `scipy.spatial.distance.jensenshannon`. The ``rotation`` methods ``from_rotvec`` and ``as_rotvec`` now accept a ``degrees`` argument to specify usage of degrees instead of radians. `scipy.special` improvements ====================== Wright's generalized Bessel function for positive arguments was added as `scipy.special.wright_bessel.` An implementation of the inverse of the Log CDF of the Normal Distribution is now available via `scipy.special.ndtri_exp`. `scipy.stats` improvements ==================== Hypothesis Tests ----------------------- The Mann-Whitney-Wilcoxon test, ``mannwhitneyu``, has been rewritten. It now supports n-dimensional input, an exact test method when there are no ties, and improved documentation. Please see "Other changes" for adjustments to default behavior. The new function `scipy.stats.binomtest` replaces `scipy.stats.binom_test`. The new function returns an object that calculates a confidence intervals of the proportion parameter. Also, performance was improved from O(n) to O(log(n)) by using binary search. The two-sample version of the Cramer-von Mises test is implemented in `scipy.stats.cramervonmises_2samp`. The Alexander-Govern test is implemented in the new function `scipy.stats.alexandergovern`. The new functions `scipy.stats.barnard_exact` and `scipy.stats. boschloo_exact` respectively perform Barnard's exact test and Boschloo's exact test for 2x2 contingency tables. The new function `scipy.stats.page_trend_test` performs Page's test for ordered alternatives. The new function `scipy.stats.somersd` performs Somers' D test for ordinal association between two variables. An option, ``permutations``, has been added in `scipy.stats.ttest_ind` to perform permutation t-tests. A ``trim`` option was also added to perform a trimmed (Yuen's) t-test. The ``alternative`` parameter was added to the ``skewtest``, ``kurtosistest``, ``ranksums``, ``mood``, ``ansari``, ``linregress``, and ``spearmanr`` functions to allow one-sided hypothesis testing. Sample statistics ----------------------- The new function `scipy.stats.differential_entropy` estimates the differential entropy of a continuous distribution from a sample. The ``boxcox`` and ``boxcox_normmax`` now allow the user to control the optimizer used to minimize the negative log-likelihood function. A new function `scipy.stats.contingency.relative_risk` calculates the relative risk, or risk ratio, of a 2x2 contingency table. The object returned has a method to compute the confidence interval of the relative risk. Performance improvements in the ``skew`` and ``kurtosis`` functions achieved by removal of repeated/redundant calculations. Substantial performance improvements in `scipy.stats.mstats.hdquantiles_sd`. The new function `scipy.stats.contingency.association` computes several measures of association for a contingency table: Pearsons contingency coefficient, Cramer's V, and Tschuprow's T. The parameter ``nan_policy`` was added to `scipy.stats.zmap` to provide options for handling the occurrence of ``nan`` in the input data. The parameter ``ddof`` was added to `scipy.stats.variation` and `scipy.stats.mstats.variation`. The parameter ``weights`` was added to `scipy.stats.gmean`. Statistical Distributions ------------------------------- We now vendor and leverage the Boost C++ library to address a number of previously reported issues in ``stats``. Notably, ``beta``, ``binom``, ``nbinom`` now have Boost backends, and it is straightforward to leverage the backend for additional functions. The skew Cauchy probability distribution has been implemented as `scipy.stats.skewcauchy`. The Zipfian probability distribution has been implemented as `scipy.stats.zipfian`. The new distributions ``nchypergeom_fisher`` and ``nchypergeom_wallenius`` implement the Fisher and Wallenius versions of the noncentral hypergeometric distribution, respectively. The generalized hyperbolic distribution was added in `scipy.stats.genhyperbolic`. The studentized range distribution was added in `scipy.stats.studentized_range`. `scipy.stats.argus` now has improved handling for small parameter values. Better argument handling/preparation has resulted in performance improvements for many distributions. The ``cosine`` distribution has added ufuncs for ``ppf``, ``cdf``, ``sf``, and ``isf`` methods including numerical precision improvements at the edges of the support of the distribution. An option to fit the distribution to data by the method of moments has been added to the ``fit`` method of the univariate continuous distributions. Other -------- `scipy.stats.bootstrap` has been added to allow estimation of the confidence interval and standard error of a statistic. The new function `scipy.stats.contingency.crosstab` computes a contingency table (i.e. a table of counts of unique entries) for the given data. `scipy.stats.NumericalInverseHermite` enables fast random variate sampling and percentile point function evaluation of an arbitrary univariate statistical distribution. New `scipy.stats.qmc` module ---------------------------------------- This new module provides Quasi-Monte Carlo (QMC) generators and associated helper functions. It provides a generic class `scipy.stats.qmc.QMCEngine` which defines a QMC engine/sampler. An engine is state aware: it can be continued, advanced and reset. 3 base samplers are available: - `scipy.stats.qmc.Sobol` the well known Sobol low discrepancy sequence. Several warnings have been added to guide the user into properly using this sampler. The sequence is scrambled by default. - `scipy.stats.qmc.Halton`: Halton low discrepancy sequence. The sequence is scrambled by default. - `scipy.stats.qmc.LatinHypercube`: plain LHS design. And 2 special samplers are available: - `scipy.stats.qmc.MultinomialQMC`: sampling from a multinomial distribution using any of the base `scipy.stats.qmc.QMCEngine`. - `scipy.stats.qmc.MultivariateNormalQMC`: sampling from a multivariate Normal using any of the base `scipy.stats.qmc.QMCEngine`. The module also provide the following helpers: - `scipy.stats.qmc.discrepancy`: assess the quality of a set of points in terms of space coverage. - `scipy.stats.qmc.update_discrepancy`: can be used in an optimization loop to construct a good set of points. - `scipy.stats.qmc.scale`: easily scale a set of points from (to) the unit interval to (from) a given range. *********************** Deprecated features *********************** `scipy.linalg` deprecations ==================== - `scipy.linalg.pinv2` is deprecated and its functionality is completely subsumed into `scipy.linalg.pinv` - Both ``rcond``, ``cond`` keywords of `scipy.linalg.pinv` and `scipy.linalg.pinvh` were not working and now are deprecated. They are now replaced with functioning ``atol`` and ``rtol`` keywords with clear usage. `scipy.spatial` deprecations ===================== - `scipy.spatial.distance` metrics expect 1d input vectors but will call ``np.squeeze`` on their inputs to accept any extra length-1 dimensions. That behaviour is now deprecated. ************************************** Backwards incompatible changes ************************************** ***************** Other changes ***************** We now accept and leverage performance improvements from the ahead-of-time Python-to-C++ transpiler, Pythran, which can be optionally disabled (via ``export SCIPY_USE_PYTHRAN=0``) but is enabled by default at build time. There are two changes to the default behavior of `scipy.stats.mannwhitenyu`: - For years, use of the default ``alternative=None`` was deprecated; explicit ``alternative`` specification was required. Use of the new default value of ``alternative``, "two-sided", is now permitted. - Previously, all p-values were based on an asymptotic approximation. Now, for small samples without ties, the p-values returned are exact by default. Support has been added for PEP 621 (project metadata in ``pyproject.toml``) We now support a Gitpod environment to reduce the barrier to entry for SciPy development; for more details see :ref:`quickstart-gitpod`. ********* Authors ********* * @endolith * Jelle Aalbers + * Adam + * Tania Allard + * Sven Baars + * Max Balandat + * baumgarc + * Christoph Baumgarten * Peter Bell * Lilian Besson * Robinson Besson + * Max Bolingbroke * Blair Bonnett + * Jordão Bragantini * Harm Buisman + * Evgeni Burovski * Matthias Bussonnier * Dominic C * CJ Carey * Ramón Casero + * Chachay + * charlotte12l + * Benjamin Curtice Corbett + * Falcon Dai + * Ian Dall + * Terry Davis * droussea2001 + * DWesl + * dwight200 + * Thomas J.

Enhancement Request: SuperLU_dist/SuperLU_mt replace current scipy.sparse.superLU
by Neil Godber June 9, 2021

June 9, 2021

Hi dev-list, I've logged an enhancement request on github to bring the parallel versions of SuperLU into scipy. As requested I'm circulating the enhancement here to solicit comment/feedback/engagement. Content of request is as follows (with light editing and links): "Is your feature request related to a problem? Please describe. The direct solution of sparse matrices is a common problem that arises across many domains. Current scipy.sparse.linalg provides spsolve and splu to solve such classes of problems. Neither solution appears to utilise more than one or two threads leaving a lot of the available compute on modern machines unused. Other solutions (MUMPS, Pardiso) exploit multicore processors but are either minimally supported and/or locked behind proprietary libraries. Describe the solution you'd like Fortunately SuperLU has two multithreaded implementations superLU_mt and superLU_dt, both actively maintained (SuperLU: Home Page (nersc.gov) <https://portal.nersc.gov/project/sparse/superlu/>). Ideally SciPy would replace the current sequential implementation with one of the parallel implementations to yield large performance improvements. Describe alternatives you've considered pyMKL (Pardiso dwfmarchant/pyMKL: Python wrappers to Intel MKL routines (github.com) <https://github.com/dwfmarchant/pyMKL>) - MKL with issues associated with that for non Intel processors, unmaintained relatively to scipy, PyTrilinos (implements all three superLU types but only available on osx and linux PyTrilinos | Trilinos <https://trilinos.github.io/pytrilinos.html>), petsc (petsc4py PETSc / petsc · GitLab <https://gitlab.com/petsc/petsc>) (implements all three superLU types but only available on osx and linux). All are relatively inaccessible compared to ubiquity and accessibility of scipy. Additional context (e.g. screenshots) Anecdotally large number of projects use various non scipy sparse solvers to achieve high level of performance. This comes with considerable time and maintenance investment. It would be fantastic for scipy to provide a 'performance competitive' sparse direct solver out of the hood as it does for dense matrices." Cheers, Neil

Minimal sparse array interface
by Stefan van der Walt June 4, 2021

June 4, 2021

Hi everyone, Several times now, I've needed exactly what is available in scipy.sparse but with an array interface, instead of a matrix interface. Having such an interface would also simplify matters for libraries such as NetworkX and scikit-learn. I am aware of pydata.sparse, but that seems like quite a bit more than is needed here (higher dimensions, optimizations via numba; I'm not clear on the linear algebra status). Would it make sense to add a minimal interface on top of the SciPy sparse matrices that exposes a NumPy array interface? Eventually that could become the default (although it probably implies a larger refactor of the underlying classes). Best regards, Stéfan
