About the apply in GSoD
by Christian Nakata June 25, 2020

June 25, 2020

Hello members of Numpy Community My name is Christian Takashi Nakata Currently, I'm working with computer vision in my master's degree and your project ideas for the GSoD caught my attention. I've always wanted to work on open source projects, especially in libraries that I usually use. I would like to begin contributing to the Numpy documentation. However, I never worked with open source projects and I wanted to know where I should begin to write a GSoD project proposal. I would like to work with refactoring the current documentation aimed at beginners. For example, in my opinion, the page "NumPy: the absolute basics for beginners" is too verbose. The amount of information on that page can blur useful information from beginner users. The page could be divided into subtopics that jump to other pages, minimizing the amount of information that the user will face for the first time. Together, I intend to create new How Tos so that beginners will find it easier to work with the library. E.g. finishing the "How to read and write data using NumPy" page. Best regards, Christian T. Nakata

ANN: randomgen 1.19.0 release
by Kevin Sheppard June 24, 2020

June 24, 2020

randomgen 1.19.0 has been released with bug fixes and new features. *New Features* - A helper class that lets users define custom bit generators in Python (slow) or numba (fast). This simplifies experimenting with alternative configurations. The UserBitGenerator can be used with numpy.random.Generator to produce variants from a wide range of distributions. https://bashtage.github.io/randomgen/custom-bit-generators.html - New bit generators: - PCG64DXSM - The cheap-multiplier variant that produces output before updating the state. This generator may become the default in NumPy in the future and is the 2.0 version of PCG64. - LCG128Mix - A 128-bit LCG with a settable multiplier, increment, and output function. This generator nests both PCG64 and PCG64DXSM as special cases. It also can act as a standard 128bit LCG/MCG. - EFIIX64 (x48 variant) - Chris Doty's stream cipher-like generator - SFC64 with settable counter increment which allows distinct streams to be produced from the same SeedSequence. - LXM - A generator that mixes the output of a 64 bit-LCG and a 256bit Xorshift. - ExtendedGenerator contains methods for producing variants that are not included in numpy.random.Generator. *Deprecations* Both Generator and RandomState have been officially deprecated. The NumPy versions are both better maintained and feature-rich. *Other* All bit generators have been tested output at least 1TB (many to 4TB) both as single streams, interleaved and interleaved with 4 or 8196 other bit generators. When interleaved, the additional generators were constructed using both SeedSequence.spawn and jumped (when available). https://bashtage.github.io/randomgen/testing.html

Guidelines for NumPy tutorials
by Ben Nathanson June 22, 2020

June 22, 2020

I've submitted PR #11 in the new numpy-tutorials repo (https://github.com/numpy/numpy-tutorials/pull/11) to provide a checklist and standard style for writing tutorials. Added tutorial content is an objective of NEP 44. We're expecting part of the content to come from new contributors (for instance, through Ryan Cooper's generous offer to get his students involved, https://mail.python.org/pipermail/numpy-discussion/2020-May/080715.htmll). The PR will provide a guide for all contributors to work from. While "tutorial" is often used broadly for introductory material, here it is closely defined: a multistep participatory walkthrough for a user new to NumPy. This is the meaning of "tutorial" in NEP 44; it was originally distinguished from other kinds of documentation by Daniele Procida (https://documentation.divio.com/tutorials/). One goal of the PR, in fact, is to make sure the tutorial stays a tutorial and doesn't mission-creep into other kinds of introductory documentation. Procida's insight is that mission creep like this leads to failed docs. At today's docs meeting it was suggested that the PR be announced on the mailing list for possible further comment.

ANN: SciPy 1.5.0
by Tyler Reddy June 22, 2020

June 22, 2020

Hi all, On behalf of the SciPy development team I'm pleased to announce the release of SciPy 1.5.0. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.5.0 One of a few ways to install this release with pip: pip install scipy==1.5.0 ========================== SciPy 1.5.0 Release Notes ========================== SciPy 1.5.0 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 1.5.x branch, and on adding new features on the master branch. This release requires Python 3.6+ and NumPy 1.14.5 or greater. For running on PyPy, PyPy3 6.0+ and NumPy 1.15.0 are required. Highlights of this release ---------------------------------- - wrappers for more than a dozen new ``LAPACK`` routines are now available in `scipy.linalg.lapack` - Improved support for leveraging 64-bit integer size from linear algebra backends - addition of the probability distribution for two-sided one-sample Kolmogorov-Smirnov tests New features ============ `scipy.cluster` improvements --------------------------------------- Initialization of `scipy.cluster.vq.kmeans2` using ``minit="++"`` had a quadratic complexity in the number of samples. It has been improved, resulting in a much faster initialization with quasi-linear complexity. `scipy.cluster.hierarchy.dendrogram` now respects the ``matplotlib`` color palette `scipy.fft` improvements ---------------------------------- A new keyword-only argument ``plan`` is added to all FFT functions in this module. It is reserved for passing in a precomputed plan from libraries providing a FFT backend (such as ``PyFFTW`` and ``mkl-fft``), and it is currently not used in SciPy. `scipy.io` improvements --------------------------------- `scipy.io.wavfile` error messages are more explicit about what's wrong, and extraneous bytes at the ends of files are ignored instead of raising an error when the data has successfully been read. `scipy.io.loadmat` gained a ``simplify_cells`` parameter, which if set to ``True`` simplifies the structure of the return value if the ``.mat`` file contains cell arrays. ``pathlib.Path`` objects are now supported in `scipy.io` Matrix Market I/O functions `scipy.linalg` improvements -------------------------------------- `scipy.linalg.eigh` has been improved. Now various ``LAPACK`` drivers can be selected at will and also subsets of eigenvalues can be requested via ``subset_by_value`` keyword. Another keyword ``subset_by_index`` is introduced. Keywords ``turbo`` and ``eigvals`` are deprecated. Similarly, standard and generalized Hermitian eigenvalue ``LAPACK`` routines ``?<sy/he>evx`` are added and existing ones now have full ``_lwork`` counterparts. Wrappers for the following ``LAPACK`` routines have been added to `scipy.linalg.lapack`: - ``?getc2``: computes the LU factorization of a general matrix with complete pivoting - ``?gesc2``: solves a linear system given an LU factorization from ``?getc2`` - ``?gejsv``: computes the singular value decomposition of a general matrix with higher accuracy calculation of tiny singular values and their corresponding singular vectors - ``?geqrfp``: computes the QR factorization of a general matrix with non-negative elements on the diagonal of R - ``?gtsvx``: solves a linear system with general tridiagonal matrix - ``?gttrf``: computes the LU factorization of a tridiagonal matrix - ``?gttrs``: solves a linear system given an LU factorization from ``?gttrf`` - ``?ptsvx``: solves a linear system with symmetric positive definite tridiagonal matrix - ``?pttrf``: computes the LU factorization of a symmetric positive definite tridiagonal matrix - ``?pttrs``: solves a linear system given an LU factorization from ``?pttrf`` - ``?pteqr``: computes the eigenvectors and eigenvalues of a positive definite tridiagonal matrix - ``?tbtrs``: solves a linear system with a triangular banded matrix - ``?csd``: computes the Cosine Sine decomposition of an orthogonal/unitary matrix Generalized QR factorization routines (``?geqrf``) now have full ``_lwork`` counterparts. `scipy.linalg.cossin` Cosine Sine decomposition of unitary matrices has been added. The function `scipy.linalg.khatri_rao`, which computes the Khatri-Rao product, was added. The new function `scipy.linalg.convolution_matrix` constructs the Toeplitz matrix representing one-dimensional convolution. `scipy.optimize` improvements ----------------------------------------- The finite difference numerical differentiation used in various ``minimize`` methods that use gradients has several new features: - 2-point, 3-point, or complex step finite differences can be used. Previously only a 2-step finite difference was available. - There is now the possibility to use a relative step size, previously only an absolute step size was available. - If the ``minimize`` method uses bounds the numerical differentiation strictly obeys those limits. - The numerical differentiation machinery now makes use of a simple cache, which in some cases can reduce the number of function evaluations. - ``minimize``'s ``method= 'powell'`` now supports simple bound constraints There have been several improvements to `scipy.optimize.linprog`: - The ``linprog`` benchmark suite has been expanded considerably. - ``linprog``'s dense pivot-based redundancy removal routine and sparse presolve are faster - When ``scikit-sparse`` is available, solving sparse problems with ``method='interior-point'`` is faster The caching of values when optimizing a function returning both value and gradient together has been improved, avoiding repeated function evaluations when using a ``HessianApproximation`` such as ``BFGS``. ``differential_evolution`` can now use the modern ``np.random.Generator`` as well as the legacy ``np.random.RandomState`` as a seed. `scipy.signal` improvements -------------------------------------- A new optional argument ``include_nyquist`` is added to ``freqz`` functions in this module. It is used for including the last frequency (Nyquist frequency). `scipy.signal.find_peaks_cwt` now accepts a ``window_size`` parameter for the size of the window used to calculate the noise floor. `scipy.sparse` improvements ---------------------------------------- Outer indexing is now faster when using a 2d column vector to select column indices. `scipy.sparse.lil.tocsr` is faster Fixed/improved comparisons between pydata sparse arrays and sparse matrices BSR format sparse multiplication performance has been improved. `scipy.sparse.linalg.LinearOperator` has gained the new ``ndim`` class attribute `scipy.spatial` improvements --------------------------------------- `scipy.spatial.geometric_slerp` has been added to enable geometric spherical linear interpolation on an n-sphere `scipy.spatial.SphericalVoronoi` now supports calculation of region areas in 2D and 3D cases The tree building algorithm used by ``cKDTree`` has improved from quadratic worst case time complexity to loglinear. Benchmarks are also now available for building and querying of balanced/unbalanced kd-trees. `scipy.special` improvements ---------------------------------------- The following functions now have Cython interfaces in `cython_special`: - `scipy.special.erfinv` - `scipy.special.erfcinv` - `scipy.special.spherical_jn` - `scipy.special.spherical_yn` - `scipy.special.spherical_in` - `scipy.special.spherical_kn` `scipy.special.log_softmax` has been added to calculate the logarithm of softmax function. It provides better accuracy than ``log(scipy.special.softmax(x))`` for inputs that make softmax saturate. `scipy.stats` improvements ------------------------------------ The function for generating random samples in `scipy.stats.dlaplace` has been improved. The new function is approximately twice as fast with a memory footprint reduction between 25 % and 60 % (see gh-11069). `scipy.stats` functions that accept a seed for reproducible calculations using random number generation (e.g. random variates from distributions) can now use the modern ``np.random.Generator`` as well as the legacy ``np.random.RandomState`` as a seed. The ``axis`` parameter was added to `scipy.stats.rankdata`. This allows slices of an array along the given axis to be ranked independently. The ``axis`` parameter was added to `scipy.stats.f_oneway`, allowing it to compute multiple one-way ANOVA tests for data stored in n-dimensional arrays. The performance of ``f_oneway`` was also improved for some cases. The PDF and CDF methods for ``stats.geninvgauss`` are now significantly faster as the numerical integration to calculate the CDF uses a Cython based ``LowLevelCallable``. Moments of the normal distribution (`scipy.stats.norm`) are now calculated using analytical formulas instead of numerical integration for greater speed and accuracy Moments and entropy trapezoidal distribution (`scipy.stats.trapz`) are now calculated using analytical formulas instead of numerical integration for greater speed and accuracy Methods of the truncated normal distribution (`scipy.stats.truncnorm`), especially ``_rvs``, are significantly faster after a complete rewrite. The `fit` method of the Laplace distribution, `scipy.stats.laplace`, now uses the analytical formulas for the maximum likelihood estimates of the parameters. Generation of random variates is now thread safe for all SciPy distributions. 3rd-party distributions may need to modify the signature of the ``_rvs()`` method to conform to ``_rvs(self, ..., size=None, random_state=None)``. (A one-time VisibleDeprecationWarning is emitted when using non-conformant distributions.) The Kolmogorov-Smirnov two-sided test statistic distribution (`scipy.stats.kstwo`) was added. Calculates the distribution of the K-S two-sided statistic ``D_n`` for a sample of size n, using a mixture of exact and asymptotic algorithms. The new function ``median_abs_deviation`` replaces the deprecated ``median_absolute_deviation``. The ``wilcoxon`` function now computes the p-value for Wilcoxon's signed rank test using the exact distribution for inputs up to length 25. The function has a new ``mode`` parameter to specify how the p-value is to be computed. The default is ``"auto"``, which uses the exact distribution for inputs up to length 25 and the normal approximation for larger inputs. Added a new Cython-based implementation to evaluate guassian kernel estimates, which should improve the performance of ``gaussian_kde`` The ``winsorize`` function now has a ``nan_policy`` argument for refined handling of ``nan`` input values. The ``binned_statistic_dd`` function with ``statistic="std"`` performance was improved by ~4x. ``scipy.stats.kstest(rvs, cdf,...)`` now handles both one-sample and two-sample testing. The one-sample variation uses `scipy.stats.ksone` (or `scipy.stats.kstwo` with back off to `scipy.stats.kstwobign`) to calculate the p-value. The two-sample variation, invoked if ``cdf`` is array_like, uses an algorithm described by Hodges to compute the probability directly, only backing off to `scipy.stats.kstwo` in case of overflow. The result in both cases is more accurate p-values, especially for two-sample testing with smaller (or quite different) sizes. `scipy.stats.maxwell` performance improvements include a 20 % speed up for `fit()`` and 5 % for ``pdf()`` `scipy.stats.shapiro` and `scipy.stats.jarque_bera` now return a named tuple for greater consistency with other ``stats`` functions Deprecated features ================ `scipy` deprecations ---------------------------- `scipy.special` changes -------------------------------- The ``bdtr``, ``bdtrc``, and ``bdtri`` functions are deprecating non-negative non-integral ``n`` arguments. `scipy.stats` changes ----------------------------- The function ``median_absolute_deviation`` is deprecated. Use ``median_abs_deviation`` instead. The use of the string ``"raw"`` with the ``scale`` parameter of ``iqr`` is deprecated. Use ``scale=1`` instead. Backwards incompatible changes ========================== `scipy.interpolate` changes ------------------------------------- `scipy.linalg` changes ------------------------------ The output signatures of ``?syevr``, ``?heevr`` have been changed from ``w, v, info`` to ``w, v, m, isuppz, info`` The order of output arguments ``w``, ``v`` of ``<sy/he>{gv, gvd, gvx}`` is swapped. `scipy.signal` changes ------------------------------- The output length of `scipy.signal.upfirdn` has been corrected, resulting outputs may now be shorter for some combinations of up/down ratios and input signal and filter lengths. `scipy.signal.resample` now supports a ``domain`` keyword argument for specification of time or frequency domain input. Other changes ============= Improved support for leveraging 64-bit integer size from linear algebra backends in several parts of the SciPy codebase. Shims designed to ensure the compatibility of SciPy with Python 2.7 have now been removed. Many warnings due to unused imports and unused assignments have been addressed. Many usage examples were added to function docstrings, and many input validations and intuitive exception messages have been added throughout the codebase.

NumPy 1.19.0 released
by Charles R Harris June 20, 2020

June 20, 2020

Hi All, On behalf of the NumPy team I am pleased to announce that NumPy 1.19.0 has been released. This NumPy release supports Python 3.6-3.8 and is marked by the removal of much technical debt: support for Python 2 has been removed, many deprecations have been expired, and documentation has been improved. The polishing of the random module continues apace with bug fixes and better usability from Cython. Perhaps the most interesting thing for users will be the availability of wheels for aarch64 and PyPY. Downstream developers should use Cython >= 0.29.16 for Python 3.8 support and OpenBLAS >= 3.7 to avoid wrong results on the Skylake architecture. The NumPy Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.19.0/>, source archives, release notes, and wheel hashes are available from Github <https://github.com/numpy/numpy/releases/tag/v1.19.0>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. *Contributors* A total of 126 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - Alex Henrie - Alexandre de Siqueira + - Andras Deak - Andrea Sangalli + - Andreas Klöckner + - Andrei Shirobokov + - Anirudh Subramanian + - Anne Bonner - Anton Ritter-Gogerly + - Benjamin Trendelkamp-Schroer + - Bharat Raghunathan - Brandt Bucher + - Brian Wignall - Bui Duc Minh + - Changqing Li + - Charles Harris - Chris Barker - Chris Holland + - Christian Kastner + - Chunlin + - Chunlin Fang + - Damien Caliste + - Dan Allan - Daniel Hrisca - Daniel Povey + - Dustan Levenstein + - Emmanuelle Gouillart + - Eric Larson - Eric M.

NumPy team update
by Ralf Gommers June 19, 2020

June 19, 2020

Hi all, The NumPy team is growing, and it's awesome to see everything that is going on. Hard to keep up with, but that's a good thing! I think it's a good time for an update on people who gained commit rights, or joined one of the teams we now have. For those who haven't seen it yet, we have a team gallery at https://numpy.org/gallery/team.html. It isn't yet updated for the changes in this email, but gives a good picture of the current state. Matti Picus joined the Steering Council. He has been one of the driving forces behind NumPy for well over two years now, and we're very glad to have him join the council. Ross Barnowski, Melissa Weber Mendonça, Josh Wilson and Bas van Beek gained commit rights. Ross has worked on the docs and reviewed lots of doc PRs for the last six months. Melissa has led the doc structuring and tutorial writing effort and has done a good amount of f2py maintenance as well. Josh and Bas have been pushing the type annotation work forward, first in the numpy-stubs repo and now in master. It's great to have experts in all these topics join the team. Furthermore, we now have 10+ people in the community calls, the triage calls and the docs team calls (all bi-weekly and on the NumPy community calendar [1] - everyone is welcome). And there's more going on - I feel like I should mention some of the other excellent work going on: A lot of work is going into SIMD optimizations. Sayed Adel has made very nice progress on implementing universal intrinsics (NEP 38), and Raghuveer Devulapalli, Chunlin Fang and others have contributed SSE/AVX and ARM Neon implementations for many functions. For the website, Shaloo Shalini has continued working on new case studies, we're about to merge a really nice one on tracking animal movement. Ben Nathanson has contributed his technical writing and editing skills to improve our website and documentation content. And Isabela Presedo-Floyd has taken up the challenge of redesigning the NumPy logo, and we're nearing the end of the process there. The survey team has also been working hard. Inessa Pawson, Xiaoyi Deng, Stephanie Mendoza, Ross Barnowski, Sebastian Berg and a number of volunteers for translations are getting a really well-designed survey together. And then of course there's both old hands and new people doing the regular maintenance and enhancement work on the main repo. Writing this email started with "we just gave out some commit rights, we should put that on the mailing list". Then I realized there's lots of other people and activities that deserve a shout out. And probably more that I forgot (if so, apologies!). I'll stop here - thanks everyone for all you do! Cheers, Ralf [1] https://calendar.google.com/calendar?cid=YmVya2VsZXkuZWR1X2lla2dwaWdtMjMyam…
