New feature: fitting distributions to censored data.
by Warren Weckesser 28 Aug '22

28 Aug '22

Hey folks, A new enhancement for fitting probability distributions to censored data by maximum likelihood estimation is in progress in https://github.com/scipy/scipy/pull/13699 This is a feature in the statistics roadmap, and is part of the work for the CZI EOSS cycle 1 grant. Censored data is data where the true value of the measurement is unknown, but there is a known bound. The common terminology is: * left-censored: The true value is greater than some known bound. * right-censored: The true value is less than some known bound. * interval-censored: The true value is between known bounds. (By allowing the bounds to be +inf and -inf, we can think of all these cases as interval-censored.) In the PR, a new class, `CensoredData`, is defined to represent censored data. The `fit` method of the univariate continuous distributions is updated to accept an instance of `CensoredData`. The `CensoredData` class constructor accepts two arrays, `lower` and `upper`, to hold the known bounds of the data. (If `lower[i] == upper[i]`, it means that data value is not censored.) Because it is quite common for data to be encountered where the only censored values in the data set are either all right-censored or all left-censored, two convenience methods, `CensoredData.right_censored(x, censored)` and `CensoredData.left_censored(x, censored)`, are provide to create a `CensoredData` instance from an array of values and a corresponding boolean array that indicates if the value is censored. Here's a quick example, with data from https://www.itl.nist.gov/div898/handbook/apr/section4/apr413.htm. The data table shows 10 regular values and 10 right-censored values. The results reported there for fitting the two-parameter Weibull distribution (location fixed at 0) to that data are shape = 1.7208 scale = 606.5280 Here's the calculation using the proposed API in SciPy: In [55]: from scipy.stats import weibull_min, CensoredData Create the `CensoredData` instance: In [56]: x = np.array([54, 187, 216, 240, 244, 335, 361, 373, 375, 386] + [500]*10) In [57]: data = CensoredData.right_censored(x, x == 500) In [58]: print(data) CensoredData(20 values: 10 not censored, 10 right-censored) Fit `weibull_min` (with the location fixed at 0) to the censored data: In [59]: shape, loc, scale = weibull_min.fit(data, floc=0) In [60]: shape Out[60]: 1.720797180719942 In [61]: scale Out[61]: 606.527565269458 Matt Haberland has already suggested quite a few improvements to the PR. Additional comments would be appreciated. Warren

proposal to use SciPy project funds for build and CI improvements
by Ralf Gommers 13 Apr '22

13 Apr '22

Hi all, I'd like to make a proposal to use some project funds to make faster progress on moving to a new build system and improving our CI timeout issues. Because this is the first such proposal, let me first deal with the meta issue of _how_ to deal with this. At the start of the year I co-wrote NEP 48 (https://numpy.org/neps/nep-0048-spending-project-funds.html) to have a framework for NumPy for spending project funds. I'd like to follow that NEP also for SciPy. So I'll make the proposal here, in accordance with that NEP, and then the other thing is to figure out where to put it up as a PR (or wiki page, or ...). For that my proposal is: create a new repo called something like `project-mgmt`, where we can put such proposals as well as meeting minutes, presentations, and other content. And have a single summary page in Markdown format with a list of all proposals made, linking out to the full proposals. On to the actual proposal, keeping in mind https://numpy.org/neps/nep-0048-spending-project-funds.html#defining-fundab… . Title: Accelerating the move to Meson as the SciPy build system Cost: $12,000 Time duration: 3 months Team members: Matthew Brett (funded), Ralf Gommers (unfunded), Gagandeep Singh (unfunded), Smit Lunagariya (funded) Context: 1. Multiple people recently told me that our current build system and CI issues are a pain point for working on SciPy. We have CI timeouts on our main repo, scipy-wheels is a pain, conda-forge is also timing out on aarch64 and ppc64le build. And I've found myself spending a whole day or weekend several times in the past months to fix broken CI jobs due to build/packaging issues. 2. About 4 months ago, I wrote an RFC to move to Meson as a build system, see https://github.com/scipy/scipy/issues/13615. Since then I have spent a lot of time on this, and also used Quansight Labs funding to get one of my colleagues, Gagandeep Singh, to help me move this forward faster (and he has been super helpful). Getting a Linux + OpenBLAS dev build is close to done (16 of 20 modules complete, all that's left is `misc`, `io`, `integrate` and `signal` - probably those can be completed in the coming week). 3. Doing everything else, like adding support for Windows/aarch64/MKL/ILP64/etc. is still a lot of work. There's a tracking issue at https://github.com/rgommers/scipy/issues/22. Some of this stuff is pretty specialized, e.g., building wheels, and Fortran-on-Windows. It will take a long time to complete if it's just me spending time on the weekends. 4. Matthew Brett is available to help soon. He has written multibuild and dealt with build/packaging topics for a long time, so I think he would be able to make progress quickly. He wants to work on this topic as an independent contractor (I won't add rates here, that's for the core team to look at - but they're very reasonable). The overall goals of this effort are: 1. Get a (mostly) feature-complete Meson based build system in place by the end of October, so we can ship it in the 1.8.0 release. If all goes well, get rid of the `numpy.distutils` based build 1 release later. 2. Resolve all our CI timeout issues. If the build system alone isn't enough (it should be though), analyze the remaining issues and figure out how to tackle whatever is still problematic. The deliverables are, in order of priority: 1. Add capability to build release artifacts (wheels, sdist). I did some initial tests at the start with mesonpep517, but I have no idea if it works for SciPy and what bugs are lurking there. 2. macOS support 3. Add support for things we need to a dev.py interface (basically, like runtests.py in that it can do everything, like building docs, running benchmarks, etc.) 4. Contribute a few things we need, or that would make the build setup better, to Meson. For example, I think we'd want to be able to use `py3.install_sources` on generated targets. Of course I'm still new-ish to Meson, so it could well be that after making a proposal on the Meson issue tracker, another solution will be preferred. 5. Windows support 6. Improve build dependency detection and configuration - in particular BLAS/LAPACK flavors. 7. Clean up as many build warnings as possible, and silence the rest. The goal is to have a CI job that is completely silent (passes with `-Werror`). 8. Optimize build time further, including on CI (e.g., reuse build cache between jobs). I'd like to use 75% of the funds to pay Matthew, and 25% of the funds to take on a talented intern, Smit Lunagariya. He is comfortable working in Python, C and C++, and will be able to help with deliverables 7 and 8, as well as with testing and other tasks. Overall I'm not certain that this amount of funds is enough to complete every last deliverable on this list; it's hard to estimate. But we should certainly get close, and be able to ship a Meson build in 1.8.0. For a quick sketch of the benefits: - On my machine the build time is currently 13 minutes with numpy.distutils and 90 seconds with Meson - The build log goes from >10,000 lines (mostly noise) to ~100 lines (mostly configuration info). Why should this be a funded activity? For two reasons: (1) build and CI issues are probably the number one maintenance issue we have, and (2) most people find working on build/CI boring and painful, and hence it doesn't happen with volunteer-only activities. Even regular maintenance of our CI is hard - recently jobs have been broken for 1-2 weeks at a time a couple of times. And the scipy-wheels repo is in even worse shape. My proposal is to designate this topic as high priority, let the core team approve the compensation levels for the funded people, and get the work started. For reporting on progress and to have some accountability about how we spent the funds, I propose a short report (say 1 page, giving a status update and linking the main PRs made or issues closed) when half the funds are spent, and another such report at the end. In addition I'll plan to write a small development grant for this when the next call for that opens up, because I think we want Matthew to continue working on this after this $12,000 has been spent. I'd like to get everything as good as it can be, so other projects can easily adopt Meson as well - to also achieve my not-so-secret goal of not having to integrate numpy.distutils capabilities into setuptools once distutils is removed from Python. Thoughts? Cheers, Ralf

Contributor experience and community meetings
by Melissa Mendonça 02 Feb '22

02 Feb '22

Hello, all! As some of you may know, recently we have been awarded a joint grant for NumPy, SciPy, matplotlib and pandas, aiming to improve contributor experience and hopefully explore and execute actions that help sustain and improve our communities. You can read the full grant proposal here [1]. As part of this grant, I will be dedicating some time to SciPy. Currently, I am an active contributor to NumPy but have only started with tiny contributions to SciPy. One action that we think might be beneficial to the projects is setting up community meetings, in this case picking up on the work Pamphile Roy was doing last year. Of course, the maintainers have the final word here, but I'd like to offer help with organizing, archiving notes, and whatever else you all feel might be helpful :) For this, we must first decide on a time and date. If you can, please answer this poll with your preferred times: https://whenisgood.net/mfd5qhz We can re-use the hackmd that Pamphile set up for the notes: https://hackmd.io/pyhudrC5TgSwdJtpPldHgQ Feel free to add to this hackmd anything you think might be worth discussing to the agenda. Depending on the poll results we can figure out frequency, but initially I would be happy to organize this every two weeks, alternating time zones if we feel this would include more people. Please let me know if there are any questions, concerns or suggestions - I am looking forward to getting more involved and helping in any way I can. Cheers, Melissa [1] https://figshare.com/articles/online_resource/Advancing_an_inclusive_cultur…

ANN: SciPy 1.8.0rc4 -- please test
by Tyler Reddy 30 Jan '22

30 Jan '22

Hi all, On behalf of the SciPy development team I'm pleased to announce the release candidate SciPy 1.8.0rc4. 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/v1.8.0rc4 One of a few ways to install the release candidate with pip: pip install scipy==1.8.0rc4 ===================== SciPy 1.8.0 Release Notes ===================== Note: SciPy 1.8.0 is not released yet! SciPy 1.8.0 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 1.8.x branch, and on adding new features on the master branch. This release requires Python 3.8+ and NumPy 1.17.3 or greater. For running on PyPy, PyPy3 6.0+ is required. **************************** Highlights of this release **************************** - A sparse array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. - The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. It is currently default-off due to potential issues on Windows that we aim to resolve in the next release, but can be optionally enabled at runtime for friendly testing with an environment variable setting of ``USE_PROPACK=1``. - A new `scipy.stats.sampling` submodule that leverages the ``UNU.RAN`` C library to sample from arbitrary univariate non-uniform continuous and discrete distributions - All namespaces that were private but happened to miss underscores in their names have been deprecated. *************** New features *************** `scipy.fft` improvements ================== Added an ``orthogonalize=None`` parameter to the real transforms in `scipy.fft` which controls whether the modified definition of DCT/DST is used without changing the overall scaling. `scipy.fft` backend registration is now smoother, operating with a single registration call and no longer requiring a context manager. `scipy.integrate` improvements ======================== `scipy.integrate.quad_vec` introduces a new optional keyword-only argument, ``args``. ``args`` takes in a tuple of extra arguments if any (default is ``args=()``), which is then internally used to pass into the callable function (needing these extra arguments) which we wish to integrate. `scipy.interpolate` improvements ========================= `scipy.interpolate.BSpline` has a new method, ``design_matrix``, which constructs a design matrix of b-splines in the sparse CSR format. A new method ``from_cubic`` in ``BSpline`` class allows to convert a ``CubicSpline`` object to ``BSpline`` object. `scipy.linalg` improvements ===================== `scipy.linalg` gained three new public array structure investigation functions. `scipy.linalg.bandwidth` returns information about the bandedness of an array and can be used to test for triangular structure discovery, while `scipy.linalg.issymmetric` and `scipy.linalg.ishermitian` test the array for exact and approximate symmetric/Hermitian structure. `scipy.optimize` improvements ======================== `scipy.optimize.check_grad` introduces two new optional keyword only arguments, ``direction`` and ``seed``. ``direction`` can take values, ``'all'`` (default), in which case all the one hot direction vectors will be used for verifying the input analytical gradient function and ``'random'``, in which case a random direction vector will be used for the same purpose. ``seed`` (default is ``None``) can be used for reproducing the return value of ``check_grad`` function. It will be used only when ``direction='random'``. The `scipy.optimize.minimize` ``TNC`` method has been rewritten to use Cython bindings. This also fixes an issue with the callback altering the state of the optimization. Added optional parameters ``target_accept_rate`` and ``stepwise_factor`` for adapative step size adjustment in ``basinhopping``. The ``epsilon`` argument to ``approx_fprime`` is now optional so that it may have a default value consistent with most other functions in `scipy.optimize`. `scipy.signal` improvements ===================== Add ``analog`` argument, default ``False``, to ``zpk2sos``, and add new pairing option ``'minimal'`` to construct analog and minimal discrete SOS arrays. ``tf2sos`` uses zpk2sos; add ``analog`` argument here as well, and pass it on to ``zpk2sos``. ``savgol_coeffs`` and ``savgol_filter`` now work for even window lengths. Added the Chirp Z-transform and Zoom FFT available as `scipy.signal.CZT` and `scipy.signal.ZoomFFT`. `scipy.sparse` improvements ====================== An array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. Please refer to the `scipy.sparse` docstring for more information. ``maximum_flow`` introduces optional keyword only argument, ``method`` which accepts either, ``'edmonds-karp'`` (Edmonds Karp algorithm) or ``'dinic'`` (Dinic's algorithm). Moreover, ``'dinic'`` is used as default value for ``method`` which means that Dinic's algorithm is used for computing maximum flow unless specified. See, the comparison between the supported algorithms in `this comment <https://github.com/scipy/scipy/pull/14358#issue-684212523>`_. Parameters ``atol``, ``btol`` now default to 1e-6 in `scipy.sparse.linalg.lsmr` to match with default values in `scipy.sparse.linalg.lsqr`. Add the Transpose-Free Quasi-Minimal Residual algorithm (TFQMR) for general nonsingular non-Hermitian linear systems in `scipy.sparse.linalg.tfqmr`. The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. For some problems, this may be faster and/or more accurate than the default, ARPACK. PROPACK functionality is currently opt-in--you must specify ``USE_PROPACK=1`` at runtime to use it due to potential issues on Windows that we aim to resolve in the next release. ``sparse.linalg`` iterative solvers now have a nonzero initial guess option, which may be specified as ``x0 = 'Mb'``. The ``trace`` method has been added for sparse matrices. `scipy.spatial` improvements ====================== `scipy.spatial.transform.Rotation` now supports item assignment and has a new ``concatenate`` method. Add `scipy.spatial.distance.kulczynski1` in favour of `scipy.spatial.distance.kulsinski` which will be deprecated in the next release. `scipy.spatial.distance.minkowski` now also supports ``0<p<1``. `scipy.special` improvements ====================== The new function `scipy.special.log_expit` computes the logarithm of the logistic sigmoid function. The function is formulated to provide accurate results for large positive and negative inputs, so it avoids the problems that would occur in the naive implementation ``log(expit(x))``. A suite of five new functions for elliptic integrals: ``scipy.special.ellipr{c,d,f,g,j}``. These are the `Carlson symmetric elliptic integrals <https://dlmf.nist.gov/19.16>`_, which have computational advantages over the classical Legendre integrals. Previous versions included some elliptic integrals from the Cephes library (``scipy.special.ellip{k,km1,kinc,e,einc}``) but was missing the integral of third kind (Legendre's Pi), which can be evaluated using the new Carlson functions. The new Carlson elliptic integral functions can be evaluated in the complex plane, whereas the Cephes library's functions are only defined for real inputs. Several defects in `scipy.special.hyp2f1` have been corrected. Approximately correct values are now returned for ``z`` near ``exp(+-i*pi/3)``, fixing `#8054 <https://github.com/scipy/scipy/issues/8054>`_. Evaluation for such ``z`` is now calculated through a series derived by `López and Temme (2013) <https://arxiv.org/abs/1306.2046>`_ that converges in these regions. In addition, degenerate cases with one or more of ``a``, ``b``, and/or ``c`` a non-positive integer are now handled in a manner consistent with `mpmath's hyp2f1 implementation < https://mpmath.org/doc/current/functions/hypergeometric.html>`_, which fixes `#7340 <https://github.com/scipy/scipy/issues/7340>`_. These fixes were made as part of an effort to rewrite the Fortran 77 implementation of hyp2f1 in Cython piece by piece. This rewriting is now roughly 50% complete. `scipy.stats` improvements ===================== `scipy.stats.qmc.LatinHypercube` introduces two new optional keyword-only arguments, ``optimization`` and ``strength``. ``optimization`` is either ``None`` or ``random-cd``. In the latter, random permutations are performed to improve the centered discrepancy. ``strength`` is either 1 or 2. 1 corresponds to the classical LHS while 2 has better sub-projection properties. This construction is referred to as an orthogonal array based LHS of strength 2. In both cases, the output is still a LHS. `scipy.stats.qmc.Halton` is faster as the underlying Van der Corput sequence was ported to Cython. The ``alternative`` parameter was added to the ``kendalltau`` and ``somersd`` functions to allow one-sided hypothesis testing. Similarly, the masked versions of ``skewtest``, ``kurtosistest``, ``ttest_1samp``, ``ttest_ind``, and ``ttest_rel`` now also have an ``alternative`` parameter. Add `scipy.stats.gzscore` to calculate the geometrical z score. Random variate generators to sample from arbitrary univariate non-uniform continuous and discrete distributions have been added to the new `scipy.stats.sampling` submodule. Implementations of a C library `UNU.RAN <http://statmath.wu.ac.at/software/unuran/>`_ are used for performance. The generators added are: - TransformedDensityRejection - DiscreteAliasUrn - NumericalInversePolynomial - DiscreteGuideTable - SimpleRatioUniforms The ``binned_statistic`` set of functions now have improved performance for the ``std``, ``min``, ``max``, and ``median`` statistic calculations. ``somersd`` and ``_tau_b`` now have faster Pythran-based implementations. Some general efficiency improvements to handling of ``nan`` values in several ``stats`` functions. Added the Tukey-Kramer test as `scipy.stats.tukey_hsd`. Improved performance of `scipy.stats.argus` ``rvs`` method. Added the parameter ``keepdims`` to `scipy.stats.variation` and prevent the undesirable return of a masked array from the function in some cases. ``permutation_test`` performs an exact or randomized permutation test of a given statistic on provided data. *********************** Deprecated features *********************** Clear split between public and private API ================================ SciPy has always documented what its public API consisted of in :ref:`its API reference docs <scipy-api>`, however there never was a clear split between public and private namespaces in the code base. In this release, all namespaces that were private but happened to miss underscores in their names have been deprecated. These include (as examples, there are many more): - ``scipy.signal.spline`` - ``scipy.ndimage.filters`` - ``scipy.ndimage.fourier`` - ``scipy.ndimage.measurements`` - ``scipy.ndimage.morphology`` - ``scipy.ndimage.interpolation`` - ``scipy.sparse.linalg.solve`` - ``scipy.sparse.linalg.eigen`` - ``scipy.sparse.linalg.isolve`` All functions and other objects in these namespaces that were meant to be public are accessible from their respective public namespace (e.g. `scipy.signal`). The design principle is that any public object must be accessible from a single namespace only; there are a few exceptions, mostly for historical reasons (e.g., ``stats`` and ``stats.distributions`` overlap). For other libraries aiming to provide a SciPy-compatible API, it is now unambiguous what namespace structure to follow. See `gh-14360 <https://github.com/scipy/scipy/issues/14360>`_ for more details. Other deprecations =============== ``NumericalInverseHermite`` has been deprecated from `scipy.stats` and moved to the `scipy.stats.sampling` submodule. It now uses the C implementation of the UNU.RAN library so the result of methods like ``ppf`` may vary slightly. Parameter ``tol`` has been deprecated and renamed to ``u_resolution``. The parameter ``max_intervals`` has also been deprecated and will be removed in a future release of SciPy. *************************************** Backwards incompatible changes *************************************** - SciPy has raised the minimum compiler versions to GCC 6.3 on linux and VS2019 on windows. In particular, this means that SciPy may now use C99 and C++14 features. For more details see `here <https://docs.scipy.org/doc/scipy/reference/dev/toolchain.html>`_. - The result for empty bins for `scipy.stats.binned_statistic` with the builtin ``'std'`` metric is now ``nan``, for consistency with ``np.std``. - The function `scipy.spatial.distance.wminkowski` has been removed. To achieve the same results as before, please use the ``minkowski`` distance function with the (optional) ``w=`` keyword-argument for the given weight. ***************** Other changes ***************** Some Fortran 77 code was modernized to be compatible with NAG's nagfor Fortran compiler (see, e.g., `PR 13229 <https://github.com/scipy/scipy/pull/13229 >`_). ``threadpoolctl`` may now be used by our test suite to substantially improve the efficiency of parallel test suite runs. ********** Authors ********** * @endolith * adamadanandy + * akeemlh + * Anton Akhmerov * Marvin Albert + * alegresor + * Andrew Annex + * Pantelis Antonoudiou + * Ross Barnowski + * Christoph Baumgarten * Stephen Becker + * Nickolai Belakovski * Peter Bell * berberto + * Georgii Bocharov + * Evgeni Burovski * Matthias Bussonnier * CJ Carey * Justin Charlong + * Hood Chatham + * Dennis Collaris + * David Cottrell + * cruyffturn + * da-woods + * Anirudh Dagar * Tiger Du + * Thomas Duvernay * Dani El-Ayyass + * Castedo Ellerman + * Donnie Erb + * Andreas Esders-Kopecky + * Livio F + * Isuru Fernando * Evelyn Fitzgerald + * Sara Fridovich-Keil + * Mark E Fuller + * Ralf Gommers * Kevin Richard Green + * guiweber + * Nitish Gupta + * h-vetinari * Matt Haberland * J.

Resolve keyword collisions in scipy.stats by renaming keywords of `rv_generic.moment/interval`
by Matt Haberland 23 Jan '22

23 Jan '22

Hi team, gh-5982 (https://github.com/scipy/scipy/issues/5982) reported the keyword collision between the `alpha` shape parameter of `levy_stable` and the `alpha` parameter of that distribution's `interval` method. This particular collision occurs in `yulesimon`, too, and a similar collision occurs for the `n` shape parameter of several distributions with the `n` parameter of their `moment` method. Following the discussion in that issue, gh-13490 (https://github.com/scipy/ scipy/pull/13490/) would: - Rename the first argument of `moment` from `n` to `order`, preserving backward compatibility by accepting keyword `n` via `**kwds`. - Rename the first argument of `interval` from `alpha` to `confidence`, preserving backward compatibility by accepting keyword `alpha` via `**kwds`. - Deprecate the `n` keyword of `moment` and the `alpha` keyword of ` interval` in the documentation and with a `DeprecationWarning` as appropriate - Add a test to `tools/refguide_check.py` to guard against future collisions Please join the discussion about these changes in gh-13490, especially if you are interested in the resolution of this keyword collision or if you have concerns about the deprecation. Thanks, Matt -- Matt Haberland Assistant Professor BioResource and Agricultural Engineering 08A-3K, Cal Poly

ANN: SciPy 1.8.0rc3 -- please test
by Tyler Reddy 22 Jan '22

22 Jan '22

Hi all, On behalf of the SciPy development team I'm pleased to announce the release candidate SciPy 1.8.0rc3. 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/v1.8.0rc3 One of a few ways to install the release candidate with pip: pip install scipy==1.8.0rc3 ===================== SciPy 1.8.0 Release Notes ===================== Note: SciPy 1.8.0 is not released yet! SciPy 1.8.0 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 1.8.x branch, and on adding new features on the master branch. This release requires Python 3.8+ and NumPy 1.17.3 or greater. For running on PyPy, PyPy3 6.0+ is required. **************************** Highlights of this release **************************** - A sparse array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. - The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. It is currently default-off due to potential issues on Windows that we aim to resolve in the next release, but can be optionally enabled at runtime for friendly testing with an environment variable setting of ``USE_PROPACK=1``. - A new `scipy.stats.sampling` submodule that leverages the ``UNU.RAN`` C library to sample from arbitrary univariate non-uniform continuous and discrete distributions - All namespaces that were private but happened to miss underscores in their names have been deprecated. **************** New features **************** `scipy.fft` improvements ================== Added an ``orthogonalize=None`` parameter to the real transforms in `scipy.fft` which controls whether the modified definition of DCT/DST is used without changing the overall scaling. `scipy.fft` backend registration is now smoother, operating with a single registration call and no longer requiring a context manager. `scipy.integrate` improvements ======================== `scipy.integrate.quad_vec` introduces a new optional keyword-only argument, ``args``. ``args`` takes in a tuple of extra arguments if any (default is ``args=()``), which is then internally used to pass into the callable function (needing these extra arguments) which we wish to integrate. `scipy.interpolate` improvements ========================= `scipy.interpolate.BSpline` has a new method, ``design_matrix``, which constructs a design matrix of b-splines in the sparse CSR format. A new method ``from_cubic`` in ``BSpline`` class allows to convert a ``CubicSpline`` object to ``BSpline`` object. `scipy.linalg` improvements ===================== `scipy.linalg` gained three new public array structure investigation functions. `scipy.linalg.bandwidth` returns information about the bandedness of an array and can be used to test for triangular structure discovery, while `scipy.linalg.issymmetric` and `scipy.linalg.ishermitian` test the array for exact and approximate symmetric/Hermitian structure. `scipy.optimize` improvements ======================== `scipy.optimize.check_grad` introduces two new optional keyword only arguments, ``direction`` and ``seed``. ``direction`` can take values, ``'all'`` (default), in which case all the one hot direction vectors will be used for verifying the input analytical gradient function and ``'random'``, in which case a random direction vector will be used for the same purpose. ``seed`` (default is ``None``) can be used for reproducing the return value of ``check_grad`` function. It will be used only when ``direction='random'``. The `scipy.optimize.minimize` ``TNC`` method has been rewritten to use Cython bindings. This also fixes an issue with the callback altering the state of the optimization. Added optional parameters ``target_accept_rate`` and ``stepwise_factor`` for adapative step size adjustment in ``basinhopping``. The ``epsilon`` argument to ``approx_fprime`` is now optional so that it may have a default value consistent with most other functions in `scipy.optimize`. `scipy.signal` improvements ====================== Add ``analog`` argument, default ``False``, to ``zpk2sos``, and add new pairing option ``'minimal'`` to construct analog and minimal discrete SOS arrays. ``tf2sos`` uses zpk2sos; add ``analog`` argument here as well, and pass it on to ``zpk2sos``. ``savgol_coeffs`` and ``savgol_filter`` now work for even window lengths. Added the Chirp Z-transform and Zoom FFT available as `scipy.signal.CZT` and `scipy.signal.ZoomFFT`. `scipy.sparse` improvements ====================== An array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. Please refer to the `scipy.sparse` docstring for more information. ``maximum_flow`` introduces optional keyword only argument, ``method`` which accepts either, ``'edmonds-karp'`` (Edmonds Karp algorithm) or ``'dinic'`` (Dinic's algorithm). Moreover, ``'dinic'`` is used as default value for ``method`` which means that Dinic's algorithm is used for computing maximum flow unless specified. See, the comparison between the supported algorithms in `this comment <https://github.com/scipy/scipy/pull/14358#issue-684212523>`_. Parameters ``atol``, ``btol`` now default to 1e-6 in `scipy.sparse.linalg.lsmr` to match with default values in `scipy.sparse.linalg.lsqr`. Add the Transpose-Free Quasi-Minimal Residual algorithm (TFQMR) for general nonsingular non-Hermitian linear systems in `scipy.sparse.linalg.tfqmr`. The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via `scipy.sparse.svds` with ``solver='PROPACK'``. For some problems, this may be faster and/or more accurate than the default, ARPACK. PROPACK functionality is currently opt-in--you must specify ``USE_PROPACK=1`` at runtime to use it due to potential issues on Windows that we aim to resolve in the next release. ``sparse.linalg`` iterative solvers now have a nonzero initial guess option, which may be specified as ``x0 = 'Mb'``. The ``trace`` method has been added for sparse matrices. `scipy.spatial` improvements ====================== `scipy.spatial.transform.Rotation` now supports item assignment and has a new ``concatenate`` method. Add `scipy.spatial.distance.kulczynski1` in favour of `scipy.spatial.distance.kulsinski` which will be deprecated in the next release. `scipy.spatial.distance.minkowski` now also supports ``0<p<1``. `scipy.special` improvements ====================== The new function `scipy.special.log_expit` computes the logarithm of the logistic sigmoid function. The function is formulated to provide accurate results for large positive and negative inputs, so it avoids the problems that would occur in the naive implementation ``log(expit(x))``. A suite of five new functions for elliptic integrals: ``scipy.special.ellipr{c,d,f,g,j}``. These are the `Carlson symmetric elliptic integrals <https://dlmf.nist.gov/19.16>`_, which have computational advantages over the classical Legendre integrals. Previous versions included some elliptic integrals from the Cephes library (``scipy.special.ellip{k,km1,kinc,e,einc}``) but was missing the integral of third kind (Legendre's Pi), which can be evaluated using the new Carlson functions. The new Carlson elliptic integral functions can be evaluated in the complex plane, whereas the Cephes library's functions are only defined for real inputs. Several defects in `scipy.special.hyp2f1` have been corrected. Approximately correct values are now returned for ``z`` near ``exp(+-i*pi/3)``, fixing `#8054 <https://github.com/scipy/scipy/issues/8054>`_. Evaluation for such ``z`` is now calculated through a series derived by `López and Temme (2013) <https://arxiv.org/abs/1306.2046>`_ that converges in these regions. In addition, degenerate cases with one or more of ``a``, ``b``, and/or ``c`` a non-positive integer are now handled in a manner consistent with `mpmath's hyp2f1 implementation < https://mpmath.org/doc/current/functions/hypergeometric.html>`_, which fixes `#7340 <https://github.com/scipy/scipy/issues/7340>`_. These fixes were made as part of an effort to rewrite the Fortran 77 implementation of hyp2f1 in Cython piece by piece. This rewriting is now roughly 50% complete. `scipy.stats` improvements ===================== `scipy.stats.qmc.LatinHypercube` introduces two new optional keyword-only arguments, ``optimization`` and ``strength``. ``optimization`` is either ``None`` or ``random-cd``. In the latter, random permutations are performed to improve the centered discrepancy. ``strength`` is either 1 or 2. 1 corresponds to the classical LHS while 2 has better sub-projection properties. This construction is referred to as an orthogonal array based LHS of strength 2. In both cases, the output is still a LHS. `scipy.stats.qmc.Halton` is faster as the underlying Van der Corput sequence was ported to Cython. The ``alternative`` parameter was added to the ``kendalltau`` and ``somersd`` functions to allow one-sided hypothesis testing. Similarly, the masked versions of ``skewtest``, ``kurtosistest``, ``ttest_1samp``, ``ttest_ind``, and ``ttest_rel`` now also have an ``alternative`` parameter. Add `scipy.stats.gzscore` to calculate the geometrical z score. Random variate generators to sample from arbitrary univariate non-uniform continuous and discrete distributions have been added to the new `scipy.stats.sampling` submodule. Implementations of a C library `UNU.RAN <http://statmath.wu.ac.at/software/unuran/>`_ are used for performance. The generators added are: - TransformedDensityRejection - DiscreteAliasUrn - NumericalInversePolynomial - DiscreteGuideTable - SimpleRatioUniforms The ``binned_statistic`` set of functions now have improved performance for the ``std``, ``min``, ``max``, and ``median`` statistic calculations. ``somersd`` and ``_tau_b`` now have faster Pythran-based implementations. Some general efficiency improvements to handling of ``nan`` values in several ``stats`` functions. Added the Tukey-Kramer test as `scipy.stats.tukey_hsd`. Improved performance of `scipy.stats.argus` ``rvs`` method. Added the parameter ``keepdims`` to `scipy.stats.variation` and prevent the undesirable return of a masked array from the function in some cases. ``permutation_test`` performs an exact or randomized permutation test of a given statistic on provided data. *********************** Deprecated features *********************** Clear split between public and private API ================================ SciPy has always documented what its public API consisted of in :ref:`its API reference docs <scipy-api>`, however there never was a clear split between public and private namespaces in the code base. In this release, all namespaces that were private but happened to miss underscores in their names have been deprecated. These include (as examples, there are many more): - ``scipy.signal.spline`` - ``scipy.ndimage.filters`` - ``scipy.ndimage.fourier`` - ``scipy.ndimage.measurements`` - ``scipy.ndimage.morphology`` - ``scipy.ndimage.interpolation`` - ``scipy.sparse.linalg.solve`` - ``scipy.sparse.linalg.eigen`` - ``scipy.sparse.linalg.isolve`` All functions and other objects in these namespaces that were meant to be public are accessible from their respective public namespace (e.g. `scipy.signal`). The design principle is that any public object must be accessible from a single namespace only; there are a few exceptions, mostly for historical reasons (e.g., ``stats`` and ``stats.distributions`` overlap). For other libraries aiming to provide a SciPy-compatible API, it is now unambiguous what namespace structure to follow. See `gh-14360 <https://github.com/scipy/scipy/issues/14360>`_ for more details. Other deprecations =============== ``NumericalInverseHermite`` has been deprecated from `scipy.stats` and moved to the `scipy.stats.sampling` submodule. It now uses the C implementation of the UNU.RAN library so the result of methods like ``ppf`` may vary slightly. Parameter ``tol`` has been deprecated and renamed to ``u_resolution``. The parameter ``max_intervals`` has also been deprecated and will be removed in a future release of SciPy. ************************************** Backwards incompatible changes ************************************** - SciPy has raised the minimum compiler versions to GCC 6.3 on linux and VS2019 on windows. In particular, this means that SciPy may now use C99 and C++14 features. For more details see `here <https://docs.scipy.org/doc/scipy/reference/dev/toolchain.html>`_. - The result for empty bins for `scipy.stats.binned_statistic` with the builtin ``'std'`` metric is now ``nan``, for consistency with ``np.std``. - The function `scipy.spatial.distance.wminkowski` has been removed. To achieve the same results as before, please use the ``minkowski`` distance function with the (optional) ``w=`` keyword-argument for the given weight. ***************** Other changes ***************** Some Fortran 77 code was modernized to be compatible with NAG's nagfor Fortran compiler (see, e.g., `PR 13229 <https://github.com/scipy/scipy/pull/13229 >`_). ``threadpoolctl`` may now be used by our test suite to substantially improve the efficiency of parallel test suite runs. ********* Authors ********* * @endolith * adamadanandy + * akeemlh + * Anton Akhmerov * Marvin Albert + * alegresor + * Andrew Annex + * Pantelis Antonoudiou + * Ross Barnowski + * Christoph Baumgarten * Stephen Becker + * Nickolai Belakovski * Peter Bell * berberto + * Georgii Bocharov + * Evgeni Burovski * Matthias Bussonnier * CJ Carey * Justin Charlong + * Hood Chatham + * Dennis Collaris + * David Cottrell + * cruyffturn + * da-woods + * Anirudh Dagar * Tiger Du + * Thomas Duvernay * Dani El-Ayyass + * Castedo Ellerman + * Donnie Erb + * Andreas Esders-Kopecky + * Livio F + * Isuru Fernando * Evelyn Fitzgerald + * Sara Fridovich-Keil + * Mark E Fuller + * Ralf Gommers * Kevin Richard Green + * guiweber + * Nitish Gupta + * h-vetinari * Matt Haberland * J.

scipy.stats.mode is a reduction operation; should consume an axis
by Matt Haberland 21 Jan '22

21 Jan '22

Hi all, Like many other `scipy.stats` (e.g. `skew`) and NumPy functions (e.g. `mean`), `scipy.stats.mode` is a reduction operation that should consume the axis it operates along. This is not how it currently behaves: >>> import numpy as np >>> from scipy import stats >>> x = np.random.rand(3, 4, 5) >>> np.mean(x, axis=1).shape (3, 5) >>> stats.skew(x, axis=1).shape (3, 5) >>> stats.mode(x, axis=1).mode.shape (3, 1, 5) gh-15243 (https://github.com/scipy/scipy/pull/15423) considers this to be a bug and proposes to fix it immediately, without a deprecation cycle. However, because the change could be disruptive, it would also temporarily offer a `keepdims` parameter (like many NumPy functions) that users could set `True` to delay updating their code (albeit with a `DeprecationWarning` of its own). Some suggest that we just fix the behavior immediately, without the `keepdims` parameter or a `DeprecationWarning`. Several other options are outlined in this comment: https://github.com/scipy/scipy/pull/15423#issuecomment-1015090369 Of course, whatever ends up happening, we'll be sure to document it in the release notes. In the meantime, we'd appreciate your thoughts on the best way to treat this. Thanks! -- Matt Haberland Assistant Professor BioResource and Agricultural Engineering 08A-3K, Cal Poly

BLIS triggers segfault in scipy arpack test on i386 (aka how to use system arpack?)
by Drew Parsons 19 Jan '22

19 Jan '22

Hi Scipy Developers I'm seeing a segfault in scipy arpack tests on i386 (sparselinalg/eigen/arpack/tests/test_arpack.py) in test_hermitian_modes. The segfault occurs when Blis is set up to be used as the BLAS implementation. The test passes with OpenBLAS and Atlas. The segfault is detected in Debian CI testing. For scipy that's https://ci.debian.net/packages/s/scipy/ A failing log is located at https://ci.debian.net/data/autopkgtest/unstable/i386/s/scipy/18402204/log.gz The test log doesn't give much detail. Hacking the code manually suggests the segfault happens when calling cneupd for the complex number case, launched in arpack.py at https://github.com/scipy/scipy/blob/cd9a2597b7ee399bf9dbdead0115607d442fece… I opened up a Blis Issue at https://github.com/flame/blis/issues/602. Not clear yet why exactly the segfault occurs. I tried setting up a test fortran program using the parameters from scipy's arpack.py, but it doesn't segfault. Maybe f2py is inculpated? One workaround is to use the system libarpack.so instead of the copy vendored with scipy. The vendored version is ARPACK 3.3.0 while the latest available for Debian is 3.8.0 (and 3.9.0 upstream). README.scipy at linalg/eigen/arpack/ARPACK says it should be possible to use the system version of ARPACK, but it's not obvious how to configure this in the context of the scipy build framework. What do you recommend? Drew Parsons

Using Array API standard in SciPy
by zoerwow＠gmail.com 12 Jan '22

12 Jan '22

Hi all, The recent NumPy release provides an Array API compatible module. From NumPy release notes: > A preliminary version of the proposed Array-API is provided. This is a > step in creating a standard collection of functions that can be used across > applications such as CuPy and JAX. I've created an issue [#15354] to discuss the adoption of Array API in SciPy. As mentioned in the NumPy release notes using Array API would make a subset of SciPy functions work with array libraries other than NumPy. It doesn't introduce any new dependencies to SciPy itself. The SciPy use case of the Array API is described on the following page: https://data-apis.org/array-api/latest/use_cases.html#use-case-scipy I've got a first PR [#15395] that adds new helper functions under `scipy/_lib/_array_api_util.py`. This file is going to be a central place in SciPy to place Array API helper functions to be used across different modules. Best regards, Ivan Yashchuk [#15354] https://github.com/scipy/scipy/issues/15354 [#15395] https://github.com/scipy/scipy/pull/15395
