gear with NumPy logo
by Ralf Gommers 16 Dec '18

16 Dec '18

Hi all, I thought this nontechnical announcement was worth copying from the NumFOCUS list: you can now order clothes, mugs and phone cases with the NumPy logo on it: https://shop.spreadshirt.com/numfocus/numpy+official+logo?q=I1018707210. Cheers, Ralf

align `choices` and `sample` with Python `random` module
by Alan Isaac 13 Dec '18

13 Dec '18

I believe this was proposed in the past to little enthusiasm, with the response, "you're using a library; learn its functions". Nevertheless, given the addition of `choices` to the Python random module in 3.6, it would be nice to have the *same name* for parallel functionality in numpy.random. And given the redundancy of numpy.random.sample, it would be nice to deprecate it with the intent to reintroduce the name later, better aligned with Python's usage. Obviously numpy.random.choice exists for both cases, so this comment is not about functionality. And I accept that some will think it is not about anything. Perhaps it might be at least seen as being about this: using the same function (`choice`) with a boolean argument (`replace`) to switch between sampling strategies at least appears to violate the proposal floated at times on this list that called for two separate functions in apparently similar cases. (I am not at all trying to claim that the argument against flag parameters is definitive; I'm just mentioning that this viewpoint has already been promulgated on this list.) Cheers, Alan Isaac

Incremental rewrite of numpy.pad (gh-11358)
by Lars Grueter 12 Dec '18

12 Dec '18

Dear community, I started the rewrite of "numpy.pad" [1] some time ago and feel like it has now left the WIP status. All tests are green and the benchmarks promise significant improvements for large arrays [2]. However progress on this PR seems to have stalled somewhat. As was brought up multiple times, a reasonable concern is that introducing these changes incrementally is preferable to a single PR. This was partly possible (see [3]) but as explained further down is not trivial for the remaining changes. Concerning the suggestion to split the remaining changes I proposed 4 ways forward (copied from comment [4]): Option 1: Split this PR in smaller PRs with the requirement to pass the test suite. I expect this will make this a lot more complicated. At some points I will just have to introduce an overhead of logic to control old and new code paths at the same time. I just don't see another way because the two approaches are so different. I'm really not a fan of creating functions that work with both approaches if this leads to a weird architecture in the long run. Also while this will split the review burden into smaller pieces I think it will increase the sum of changes to review in total. Option 2: Split this PR in smaller PRs without the requirement to pass the test suite (mark appropriate tests as xfail). Create a new branch in numpy's repo just for the rewrite. I could then make my PRs against this branch without master suffering. I'm thinking of first wiping the slate, introducing shared functions (for all modes) and then incrementally introducing each "new" mode with a new PR. This would keep the review burden for each PR and the rewrite overall small and still allow benchmarking of all combined changes against master. Option 3: Squash changes in this PR and continue with a new PR to maintain clarity as this PR has gotten quite big while I was still making changes and addressing reviews. Option 4: Continue this PR. I myself think option 2 is the most elegant and best compromise between all concerns. However I can't move forward on my own as this option requires a maintainer to set up a temporary branch for me to make PRs against. So I'd like to kindly ask for your thoughts and guidance. Best regards, Lars [1] https://github.com/numpy/numpy/pull/11358 [2] https://github.com/numpy/numpy/pull/11358#issuecomment-441246090 [3] https://github.com/numpy/numpy/pull/11966 [4] https://github.com/numpy/numpy/pull/11358#issuecomment-441362401

the making of the NumPy roadmap
by Ralf Gommers 10 Dec '18

10 Dec '18

Hi all, A little while ago I wrote a blog post about the history of us constructing the roadmap we currently have: https://rgommers.github.io/2018/10/the-making-of-the-numpy-roadmap/. There was a request to post it to this list, which seems appropriate. So below it is in full. Cheers, Ralf NumPy now has a [roadmap](https://www.numpy.org/neps/index.html#roadmap) - long overdue and a major step forward for the project. We're not done yet (see [my previous post]( https://rgommers.github.io/2018/10/2018-numfocus-summit---a-summary/) on this topic) and updating the technical roadmap with new ideas and priorities should happen regularly. Despite everything having been done in the open, via minutes of in-person meetings and shared roadmap drafts on the numpy-discussion mailing list, it turns out that it's not completely clear to the community and even some maintainers how we got to this point. So now seems like a good time for a summary. ## Act 1: NumPy sprint at BIDS During 24-25 May 2018 a number of people - Stéfan van der Walt, Charles Harris, Stephan Hoyer, Matti Picus, Jarrod Millman, Nathaniel J. Smith, and Matthew Rocklin - came together at [BIDS](https://bids.berkeley.edu/) in Berkeley for a NumPy sprint. They had a productive brainstorm, which resulted in a rough draft of a roadmap posted to the mailing list. The mailing list thread, [A roadmap for NumPy - longer term planning]( https://mail.python.org/pipermail/numpy-discussion/2018-June/thread.html#78…), produced more suggestions and after incorporating those a [first pull request](https://github.com/numpy/numpy/pull/11446) was made. ## Act 2: BoF and sprint at SciPy'18 In order to collect input from as many people in the community as possible, a BoF ([birds of a feather]( https://en.wikipedia.org/wiki/Birds_of_a_feather_(computing) session) was held on 12 July 2018 during the SciPy 2018 conference in Austin. Stephan Hoyer presented an overview of recent NEPs, and Matti Picus presented the first roadmap draft and led a discussion with (I estimate) 30-40 people in which a number of new ideas were added. Other maintainers present included Charles Harris, Tyler Reddy, Ralf Gommers and Stéfan van der Walt; many other participants were developers of libraries that depend on NumPy. At this point we had a fairly complete list of roadmap items, however the document itself was still more a brainstorm dump than a roadmap document. So during the NumPy sprint after the conference on 14 July 2018 Ralf Gommers and Stephan Hoyer sat together to reshape and clean up these ideas. That resulted in [roadmap draft v2]( https://github.com/numpy/numpy/wiki/NumPy-roadmap-v2) - not yet fully polished, but getting closer to something ready for acceptance. ## Act 3: NumPy sprint at BIDS In-person meetings seem to be critical to moving a complex and important document like a project roadmap forward. So the next draft was produced during a second NumPy sprint at Berkeley during 23-27 July 2018. Present were Stéfan van der Walt, Matti Picus, Tyler Reddy and Ralf Gommers. We polished the document, worked out the [Scope of NumPy]( https://www.numpy.org/neps/scope.html) section in more detail, and integrated the roadmap in the html docs. During the sprint a [pull request](https://github.com/numpy/numpy/pull/11611) was sent, and [posted]( https://mail.python.org/pipermail/numpy-discussion/2018-July/thread.html#78…) again to the mailing list. Everyone seemed happy, and after addressing the final few review comments the roadmap was merged on 2 August 2018. *Final thought: NumPy development is accelerating at the moment, and in-person meetings and having the people and funding at BIDS to organize sprints has been a huge help. See https://github.com/BIDS-numpy/docs for an overview of what has been organized in the last year.*

ANN: SciPy 1.2.0rc2 -- please test
by Tyler Reddy 05 Dec '18

05 Dec '18

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi all, On behalf of the SciPy development team I'm pleased to announce the release candidate SciPy 1.2.0rc2. Please help us test out this release candidate -- the 1.2.x series will be an LTS release and the last to support Python 2.7. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.2.0rc2 One of a few ways to install the release candidate with pip: pip install scipy==1.2.0rc2 ========================== SciPy 1.2.0 Release Notes ========================== Note: Scipy 1.2.0 is not released yet! SciPy 1.2.0 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 1.2.x branch, and on adding new features on the master branch. This release requires Python 2.7 or 3.4+ and NumPy 1.8.2 or greater. Note: This will be the last SciPy release to support Python 2.7. Consequently, the 1.2.x series will be a long term support (LTS) release; we will backport bug fixes until 1 Jan 2020. For running on PyPy, PyPy3 6.0+ and NumPy 1.15.0 are required. Highlights of this release --------------------------- - 1-D root finding improvements with a new solver, ``toms748``, and a new unified interface, ``root_scalar`` - New ``dual_annealing`` optimization method that combines stochastic and local deterministic searching - A new optimization algorithm, ``shgo`` (simplicial homology global optimization) for derivative free optimization problems - A new category of quaternion-based transformations are available in `scipy.spatial.transform` New features ============ `scipy.ndimage` improvements --------------------------------- Proper spline coefficient calculations have been added for the ``mirror``, ``wrap``, and ``reflect`` modes of `scipy.ndimage.rotate` `scipy.fftpack` improvements --------------------------------- DCT-IV, DST-IV, DCT-I, and DST-I orthonormalization are now supported in `scipy.fftpack`. `scipy.interpolate` improvements --------------------------------- `scipy.interpolate.pade` now accepts a new argument for the order of the numerator `scipy.cluster` improvements ----------------------------- `scipy.cluster.vq.kmeans2` gained a new initialization method, kmeans++. `scipy.special` improvements ----------------------------- The function ``softmax`` was added to `scipy.special`. `scipy.optimize` improvements ------------------------------ The one-dimensional nonlinear solvers have been given a unified interface `scipy.optimize.root_scalar`, similar to the `scipy.optimize.root` interface for multi-dimensional solvers. ``scipy.optimize.root_scalar(f, bracket=[a ,b], method="brenth")`` is equivalent to ``scipy.optimize.brenth(f, a ,b)``. If no ``method`` is specified, an appropriate one will be selected based upon the bracket and the number of derivatives available. The so-called Algorithm 748 of Alefeld, Potra and Shi for root-finding within an enclosing interval has been added as `scipy.optimize.toms748`. This provides guaranteed convergence to a root with convergence rate per function evaluation of approximately 1.65 (for sufficiently well-behaved functions.) ``differential_evolution`` now has the ``updating`` and ``workers`` keywords. The first chooses between continuous updating of the best solution vector (the default), or once per generation. Continuous updating can lead to faster convergence. The ``workers`` keyword accepts an ``int`` or map-like callable, and parallelises the solver (having the side effect of updating once per generation). Supplying an ``int`` evaluates the trial solutions in N parallel parts. Supplying a map-like callable allows other parallelisation approaches (such as ``mpi4py``, or ``joblib``) to be used. ``dual_annealing`` (and ``shgo`` below) is a powerful new general purpose global optizimation (GO) algorithm. ``dual_annealing`` uses two annealing processes to accelerate the convergence towards the global minimum of an objective mathematical function. The first annealing process controls the stochastic Markov chain searching and the second annealing process controls the deterministic minimization. So, dual annealing is a hybrid method that takes advantage of stochastic and local deterministic searching in an efficient way. ``shgo`` (simplicial homology global optimization) is a similar algorithm appropriate for solving black box and derivative free optimization (DFO) problems. The algorithm generally converges to the global solution in finite time. The convergence holds for non-linear inequality and equality constraints. In addition to returning a global minimum, the algorithm also returns any other global and local minima found after every iteration. This makes it useful for exploring the solutions in a domain. `scipy.optimize.newton` can now accept a scalar or an array ``MINPACK`` usage is now thread-safe, such that ``MINPACK`` + callbacks may be used on multiple threads. `scipy.signal` improvements ---------------------------- Digital filter design functions now include a parameter to specify the sampling rate. Previously, digital filters could only be specified using normalized frequency, but different functions used different scales (e.g. 0 to 1 for ``butter`` vs 0 to π for ``freqz``), leading to errors and confusion. With the ``fs`` parameter, ordinary frequencies can now be entered directly into functions, with the normalization handled internally. ``find_peaks`` and related functions no longer raise an exception if the properties of a peak have unexpected values (e.g. a prominence of 0). A ``PeakPropertyWarning`` is given instead. The new keyword argument ``plateau_size`` was added to ``find_peaks``. ``plateau_size`` may be used to select peaks based on the length of the flat top of a peak. ``welch()`` and ``csd()`` methods in `scipy.signal` now support calculation of a median average PSD, using ``average='mean'`` keyword `scipy.sparse` improvements ---------------------------- The `scipy.sparse.bsr_matrix.tocsr` method is now implemented directly instead of converting via COO format, and the `scipy.sparse.bsr_matrix.tocsc` method is now also routed via CSR conversion instead of COO. The efficiency of both conversions is now improved. The issue where SuperLU or UMFPACK solvers crashed on matrices with non-canonical format in `scipy.sparse.linalg` was fixed. The solver wrapper canonicalizes the matrix if necessary before calling the SuperLU or UMFPACK solver. The ``largest`` option of `scipy.sparse.linalg.lobpcg()` was fixed to have a correct (and expected) behavior. The order of the eigenvalues was made consistent with the ARPACK solver (``eigs()``), i.e. ascending for the smallest eigenvalues, and descending for the largest eigenvalues. The `scipy.sparse.random` function is now faster and also supports integer and complex values by passing the appropriate value to the ``dtype`` argument. `scipy.spatial` improvements ----------------------------- The function `scipy.spatial.distance.jaccard` was modified to return 0 instead of ``np.nan`` when two all-zero vectors are compared. Support for the Jensen Shannon distance, the square-root of the divergence, has been added under `scipy.spatial.distance.jensenshannon` An optional keyword was added to the function `scipy.spatial.cKDTree.query_ball_point()` to sort or not sort the returned indices. Not sorting the indices can speed up calls. A new category of quaternion-based transformations are available in `scipy.spatial.transform`, including spherical linear interpolation of rotations (``Slerp``), conversions to and from quaternions, Euler angles, and general rotation and inversion capabilities (`spatial.transform.Rotation`), and uniform random sampling of 3D rotations (`spatial.transform.Rotation.random`). `scipy.stats` improvements --------------------------- The Yeo-Johnson power transformation is now supported (``yeojohnson``, ``yeojohnson_llf``, ``yeojohnson_normmax``, ``yeojohnson_normplot``). Unlike the Box-Cox transformation, the Yeo-Johnson transformation can accept negative values. Added a general method to sample random variates based on the density only, in the new function ``rvs_ratio_uniforms``. The Yule-Simon distribution (``yulesimon``) was added -- this is a new discrete probability distribution. ``stats`` and ``mstats`` now have access to a new regression method, ``siegelslopes``, a robust linear regression algorithm `scipy.stats.gaussian_kde` now has the ability to deal with weighted samples, and should have a modest improvement in performance Levy Stable Parameter Estimation, PDF, and CDF calculations are now supported for `scipy.stats.levy_stable`. The Brunner-Munzel test is now available as ``brunnermunzel`` in ``stats`` and ``mstats`` `scipy.linalg` improvements --------------------------- `scipy.linalg.lapack` now exposes the LAPACK routines using the Rectangular Full Packed storage (RFP) for upper triangular, lower triangular, symmetric, or Hermitian matrices; the upper trapezoidal fat matrix RZ decomposition routines are now available as well. Deprecated features =================== The functions ``hyp2f0``, ``hyp1f2`` and ``hyp3f0`` in ``scipy.special`` have been deprecated. Backwards incompatible changes ============================== LAPACK version 3.4.0 or later is now required. Building with Apple Accelerate is no longer supported. The function ``scipy.linalg.subspace_angles(A, B)`` now gives correct results for all angles. Before this, the function only returned correct values for those angles which were greater than pi/4. Support for the Bento build system has been removed. Bento has not been maintained for several years, and did not have good Python 3 or wheel support, hence it was time to remove it. The required signature of `scipy.optimize.lingprog` ``method=simplex`` callback function has changed. Before iteration begins, the simplex solver first converts the problem into a standard form that does not, in general, have the same variables or constraints as the problem defined by the user. Previously, the simplex solver would pass a user-specified callback function several separate arguments, such as the current solution vector ``xk``, corresponding to this standard form problem. Unfortunately, the relationship between the standard form problem and the user-defined problem was not documented, limiting the utility of the information passed to the callback function. In addition to numerous bug fix changes, the simplex solver now passes a user-specified callback function a single ``OptimizeResult`` object containing information that corresponds directly to the user-defined problem. In future releases, this ``OptimizeResult`` object may be expanded to include additional information, such as variables corresponding to the standard-form problem and information concerning the relationship between the standard-form and user-defined problems. The implementation of `scipy.sparse.random` has changed, and this affects the numerical values returned for both ``sparse.random`` and ``sparse.rand`` for some matrix shapes and a given seed. `scipy.optimize.newton` will no longer use Halley's method in cases where it negatively impacts convergence Other changes ============= Authors ======= * @endolith * @luzpaz * Hameer Abbasi + * akahard2dj + * Anton Akhmerov * Joseph Albert * alexthomas93 + * ashish + * atpage + * Blair Azzopardi + * Yoshiki Vázquez Baeza * Bence Bagi + * Christoph Baumgarten * Lucas Bellomo + * BH4 + * Aditya Bharti * Max Bolingbroke * François Boulogne * Ward Bradt + * Matthew Brett * Evgeni Burovski * Rafał Byczek + * Alfredo Canziani + * CJ Carey * Lucía Cheung + * Poom Chiarawongse + * Jeanne Choo + * Robert Cimrman * Graham Clenaghan + * cynthia-rempel + * Johannes Damp + * Jaime Fernandez del Rio * Dowon + * emmi474 + * Stefan Endres + * Thomas Etherington + * Piotr Figiel * Alex Fikl + * fo40225 + * Joseph Fox-Rabinovitz * Lars G * Abhinav Gautam + * Stiaan Gerber + * C.A.M.

NumPy 1.16 branch
by Charles R Harris 04 Dec '18

04 Dec '18

Hi All, Matthew Brett has built OpenBLAS 3.4+ libraries and we are successfully building wheels with them. There are few remaining PRs/issues marked for 1.16, so I expect to make the 1.16. branch in the next several days. If there are PRs, especially bug fixes, that you really, really want in 1.16, now is the time to speak up. Chuck
