Solving for Nonlinear Hamiltonian using fsolve
by #ASHWINIE GHANESH# Feb. 20, 2022

Feb. 20, 2022

Dear sir/madam, I am currently doing research on solving for a nonlinear Hamiltonian using SciPy’s fsolve method. Since my problem involved complex wavefunctions, I need a different way of solving it. Are there any resources available for me to further learn about this (excluding the one already present in SciPy’s website) ? ~AG

lsq_linear (scipy.optimize) additional options and outputs + bugfix
by scipy＠ea.tapil.com Feb. 19, 2022

Feb. 19, 2022

Hello all, I have an additional input option and output I'd like to add to the lsq_linear function in scipy.optimize. There's also a bug in the first call to lsmr that I'd like to fix where it uses the wrong tolerance. I'm new to SciPy development, so I'm not exactly sure how this process works--I opened a PR with my additions that includes documentation and testing (https://github.com/scipy/scipy/pull/15598). New features: 1. lsmr_max_iter option that gets passed to the lsmr solver; setting this higher than the default value is necessary for poorly conditioned matrices, so this enables the use of lsq_linear with poorly conditioned sparse matrices 2. x_unbounded attribute added to the OptimizeResult return value to give the user access to the unbounded least squares solution Details of the bug fix: In the first call to lsmr, the lsmr tolerance option was set to lsq_linear's tol option as opposed to lsmr_tol as it's supposed to. I corrected this (including the cases if lsmr_tol is None or 'auto') and added error checking for the lsmr_tol argument. Thanks in advance for the help! Best, Eytan

Adding the "keepdims" parameter to all the stats reduction functions
by Tirth Patel Feb. 18, 2022

Feb. 18, 2022

Hi everyone, gh-15478 (https://github.com/scipy/scipy/pull/15478) adds the `keepdims` parameter to the `_axis_nan_policy_factory` decorator to preserve reduced dimensions. The plan is to apply the decorator to all (or most) of the stats reduction functions and hypothesis tests (e.g. `tmean`, `kruskal`) for consistent nan_policy and axis tuple support. This means that all the decorated functions will get a `keepdims` parameter. NumPy is very consistent about adding the parameter to its reduction function so it seems like a worthwhile enhancement in SciPy too. Please feel free to join the discussion in gh-15478 or add your comments about this here! -- Thanks, Tirth Patel

Deprecating non-numeric array support in stats.mode
by Tirth Patel Feb. 14, 2022

Feb. 14, 2022

Hi all, gh-15573 [1] deprecates support for non-numeric arrays in stats.mode. The support was already flaky [2] and made it difficult to add the _axis_nan_policy_factory [3] decorator to the function for consistent nan_policy handling and axis tuple support [4]. Moreover, most stats functions don't support non-numeric arrays. It is still possible to find the mode of non-numeric arrays using sentinel values [5]. The deprecation was discussed in gh-15551 [6]. Please feel free to add comments here or on the related issues/PR! [1]: https://github.com/scipy/scipy/pull/15573 [2]: https://github.com/scipy/scipy/issues/9815#issuecomment-1013834361 [3]: https://github.com/scipy/scipy/blob/63472fd76eadf2c97b9aaf6f55ffc6ddce4b39b… [4]: https://github.com/scipy/scipy/pull/15516#issuecomment-1030153330 [5]: https://github.com/scipy/scipy/issues/15551#issuecomment-1035157309 [6]: https://github.com/scipy/scipy/issues/15551 -- Thanks, Tirth Patel

Feb. 13, 2022

Hi all, On behalf of the SciPy developers I'd like to welcome Atsushi Sakai and Albert Steppi as members of the core team. Atsushi has been contributing a large amount of docs, bug fixes and smaller enhancements over the past 2 years across multiple modules. Albert has made significant improvements to special.hyp2f1 over the past 6 months, and more recently he has also been active in reviewing and helping finish open PRs. Here is an overview of their SciPy PRs: https://github.com/scipy/scipy/pulls/AtsushiSakai. https://github.com/scipy/scipy/pulls/steppi I'm looking forward to their continued contributions! Cheers, Ralf P.S. my apologies for the late public announcement - Albert and Atsushi already gained commit rights in December, but I sent the above message to the wrong list back then.

`scipy.stats.fit` for fitting continuous and discrete distributions to data
by Matt Haberland Feb. 9, 2022

Feb. 9, 2022

Hi team, Several users have requested the ability to fit discrete distributions to data (e.g. gh-11948, gh-10534), and shortcomings of `rv_continuous.fit` have been noted for some distributions (e.g. gh-10908). Since distributions usually have only a few parameters to be fit, global optimization seems well suited to the general problem. With the addition of integrality constraints to some global optimizers (gh-15392), it's time to add this capability. gh-15436 <https://github.com/scipy/scipy/pull/15436> proposes the addition of `scipy.stats.fit` for fitting discrete and continuous distributions to data. Please take a look if you're interested! -- Matt Haberland Assistant Professor BioResource and Agricultural Engineering 08A-3K, Cal Poly References: gh-10534 - https://github.com/scipy/scipy/issues/10534 gh-10908 - https://github.com/scipy/scipy/issues/10908 gh-11948 - https://github.com/scipy/scipy/issues/11948 gh-15392 - https://github.com/scipy/scipy/pull/15392

scipy.optimize.milp: dedicated function for mixed integer linear programming
by Matt Haberland Feb. 9, 2022

Feb. 9, 2022

Hi team, gh-15294 <https://github.com/scipy/scipy/pull/15294> added support for integer constraints to `scipy.optimize.linprog`. The consensus in gh-14455 <https://github.com/scipy/scipy/issues/14455> was that we should also have a dedicated function for mixed integer linear programming. The purpose is to make the MILP capabilities easier to find and to provide a clean, new interface. Please join the conversation about `scipy.optimize.milp` in gh-15460 <https://github.com/scipy/scipy/pull/15460>!

ANN: SciPy 1.8.0
by Tyler Reddy Feb. 6, 2022

Feb. 6, 2022

Hi all, On behalf of the SciPy development team, I'm pleased to announce the release of SciPy 1.8.0. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.8.0 <https://github.com/scipy/scipy/releases/tag/v1.6.3> <https://github.com/scipy/scipy/releases/tag/v1.6.1> One of a few ways to install this release with pip: pip install scipy==1.8.0 ===================== SciPy 1.8.0 Release Notes ===================== 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.

NumPy 1.22.2 released
by Charles R Harris Feb. 4, 2022

Feb. 4, 2022

Hi All, On behalf of the NumPy team, I'm pleased to announce the release of NumPy 1.22.2. NumPy 1.22.2 fixes several bugs discovered after the 1.22.1 release. Notable fixes are: - Build related fixes for downstream projects and other platforms. - Various annotation fixes/additions. - Fixes for the CVE-2021-41495 complaint. - Toolchain fixes on Windows. Numpy wheels now use the 1.41 tool chain, fixing downstream link problems for projects using NumPy provided libraries on Windows. Note that OSX wheels are provided for both the x86_64 and arm64 architectures, but there are no universal2 wheels. The minimum supported OS X version is now 10.14 for the former and 11.0 for the latter. The Python versions supported in this release are 3.8-3.10. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.22.2>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.22.2>. Linux users will need pip >= 0.19.3 in order to install the manylinux2014 wheels. *Contributors* A total of 14 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - Andrew J. Hesford + - Bas van Beek - Brénainn Woodsend + - Charles Harris - Hood Chatham - Janus Heide + - Leo Singer - Matti Picus - Mukulika Pahari - Niyas Sait - Pearu Peterson - Ralf Gommers - Sebastian Berg - Serge Guelton *Pull requests merged* A total of 21 pull requests were merged for this release. - #20842: BLD: Add NPY_DISABLE_SVML env var to opt out of SVML - #20843: BUG: Fix build of third party extensions with Py_LIMITED_API - #20844: TYP: Fix pyright being unable to infer the ``real`` and ``imag``... - #20845: BUG: Fix comparator function signatures - #20906: BUG: Avoid importing ``numpy.distutils`` on import numpy.testing - #20907: MAINT: remove outdated mingw32 fseek support - #20908: TYP: Relax the return type of ``np.vectorize`` - #20909: BUG: fix f2py's define for threading when building with Mingw - #20910: BUG: distutils: fix building mixed C/Fortran extensions - #20912: DOC,TST: Fix Pandas code example as per new release - #20935: TYP, MAINT: Add annotations for ``flatiter.__setitem__`` - #20936: MAINT, TYP: Added missing where typehints in ``fromnumeric.pyi`` - #20937: BUG: Fix build_ext interaction with non numpy extensions - #20938: BUG: Fix missing intrinsics for windows/arm64 target - #20945: REL: Prepare for the NumPy 1.22.2 release. - #20982: MAINT: f2py: don't generate code that triggers ``-Wsometimes-uninitialized``. - #20983: BUG: Fix incorrect return type in reduce without initial value - #20984: ENH: review return values for PyArray_DescrNew - #20985: MAINT: be more tolerant of setuptools >= 60 - #20986: BUG: Fix misplaced return. - #20992: MAINT: Further small return value validation fixes Cheers, Charles Harris

Using the populations from differential_evolution
by Andrew Nelson Feb. 4, 2022

Feb. 4, 2022

The differential_evolution minimiser iterates over a population of solution vectors. At each iteration the energy corresponding to each of those solution vectors is calculated. As the minimiser converges there is less and less variation between the solution vectors/energies. A history of the population vectors should reveal a reasonable amount of exploration around the optimised location, especially in the last few iterations. I'm wondering if it's possible to use that history to obtain something useful. For example, does anyone know of techniques to estimate the Hessian/Jacobian from a series of samples (solution vector/energy value pairs) around the minimum? -- _____________________________________ Dr. Andrew Nelson _____________________________________
