I've been browsing the numpy source. I'm wondering about mixedmode
arithmetic on arrays. I believe the way numpy handles this is that it
never does mixed arithmetic, but instead converts arrays to a common type.
Arguably, that might be efficient for a mix of say, double and float.
Maybe not.
But for a mix of complex and a scalar type (say, CDouble * Double), it's
clearly suboptimal in efficiency.
So, do I understand this correctly? If so, is that something we should
improve?

Dear all,
I have a code using lots of "numpy.where" to make some constrained
calculations as in:
data = arange(10)
result = np.where(data == 0, 0., 1./data)
# or
data1 = arange(10)
data2 = arange(10)+1.0
result = np.where(data1 > data2, np.sqrt(data1data2), np.sqrt(data2data2))
which then produces warnings like:
/usr/bin/ipython:1: RuntimeWarning: invalid value encountered in sqrt
or for the first example:
/usr/bin/ipython:1: RuntimeWarning: divide by zero encountered in divide
How do I avoid these messages to appear?
I know that I could in principle use numpy.seterr. However, I do NOT
want to remove these warnings for other potential divide/multiply/sqrt
etc errors. Only when I am using a "where", to in fact avoid such
warnings! Note that the warnings only happen once, but since I am going
to release that code, I would like to avoid the user to get such
messages which are irrelevant here (because I am testing, with the
where, when NOT to divide by zero or take a sqrt of a negative number).
thanks!

I've posted this before, but I finally got it cleaned up for the Cookbook.
For this purpose I use a subclass of file that has methods for reading
unformatted Fortran data. See
http://www.scipy.org/Cookbook/FortranIO/FortranFile. I'd gladly see this in
numpy or scipy somewhere, but I'm not sure where it belongs.

> do j = 1,ny
> ux(i,j) = real(i*j)

> p (i,j) = real(i) + real(j)
> enddo
> enddo
> write(11) ux,uy
> write(11) p
> close(11)
> end program makeArray
When I run the above program compiled with gfortran on my Intel Mac,
I can read it back with::
>>> import numpy as np
>>> from fortranfile import FortranFile
>>> f=FortranFile('uxuyp.bin', endian='<')
>>> uxuy = f.readReals(prec='f') # 'f' for default reals
>>> len(uxuy)
400
>>> ux = np.array(uxuy[:200]).reshape((20,10)).T
>>> uy = np.array(uxuy[200:]).reshape((20,10)).T
>>> p = f.readReals('f').reshape((20,10)).T
>>> ux

The initial stage of the NumPy community survey project in partnership with
the students and faculty from the Master’s program in Survey Methodology at
the University of Michigan and the University of Maryland has been
successfully completed.
Currently, we are looking for a volunteer to help with the back translation
of the Hindi version of the survey questionnaire (Hindi into English). If
you are available, or you know someone who would be interested to help,
please leave a comment here: https://github.com/numpy/numpysurveys/issues/1

Hi All,
On behalf of the NumPy team I am pleased to announce that
NumPy 1.19.0rc2 has been released. This NumPy release supports Python
3.63.8 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/1.19.0rc2/>, source archives and release
notes are available from Github
<https://github.com/numpy/numpy/releases/tag/v1.19.0rc2>.

Reminder: June 01 Deadline for the 2020 John Hunter Excellence in Plotting contest!
by Madicken Munk 31 May '20

Dear numpy community,
My apologies for repeated inlist and crosslist posts!
I'd like to remind everybody that the 2020 John Hunter Excellence in
Plotting Contest submission deadline is June 01  only a few days away. We
welcome and look forward to your submissions!
In memory of John Hunter, we are pleased to announce the John Hunter
Excellence in Plotting Contest for 2020. This open competition aims to
highlight the importance of data visualization to scientific progress and
showcase the capabilities of open source software.
Participants are invited to submit scientific plots to be judged by a
panel. The winning entries will be announced and displayed at SciPy 2020 or
announced in the John Hunter Excellence in Plotting Contest website and
youtube channel.
John Hunter’s family are graciously sponsoring cash prizes for the winners
in the following amounts:

1st prize: $1000

2nd prize: $750

3rd prize: $500

Entries must be submitted by June 1st to the form at
https://forms.gle/SrexmkDwiAmDc7ej7

Winners will be announced at Scipy 2020 or publicly on the John Hunter
Excellence in Plotting Contest website and youtube channel

Participants do not need to attend the Scipy conference.

Entries may take the definition of “visualization” rather broadly.
Entries may be, for example, a traditional printed plot, an interactive
visualization for the web, a dashboard, or an animation.

Source code for the plot must be provided, in the form of Python code
and/or a Jupyter notebook, along with a rendering of the plot in a widely
used format. The rendering may be, for example, PDF for print, standalone
HTML and Javascript for an interactive plot, or MPEG4 for a video. If the
original data can not be shared for reasons of size or licensing, "fake"
data may be substituted, along with an image of the plot using real data.

Each entry must include a 300500 word abstract describing the plot and
its importance for a general scientific audience.

Entries will be judged on their clarity, innovation and aesthetics, but
most importantly for their effectiveness in communicating a realworld
problem. Entrants are encouraged to submit plots that were used during the
course of research or work, rather than merely being hypothetical.

SciPy and the John Hunter Excellence in Plotting Contest organizers
reserves the right to display any and all entries, whether prizewinning or
not, at the conference, use in any materials or on its website, with
attribution to the original author(s).

Past entries can be found at https://jhepc.github.io/

Questions regarding the contest can be sent to jhepc.organizers(a)gmail.com

Greetings,
This is Ryan Cooper (ME professor at University of Connecticut). I've been using Numpy in my mechanical engineering courses for years now, and I'd like to build resources for newcomers to Numpy.
Here is my proposed contribution:
Advise engineering students here at UConn to build Howto notebooks for Numpy applications. This would give the students some great experience communicating concepts and procedures to a broader community and it would help future users see how to use Numpy in different applications.
Some Howto's that I had in mind would be:
* Saving and loading Numpy arrays
* Doing fast fourier transform (FFT) on timeseries data to find natural frequencies
* Solving linear sets of equations for circuits or another linear system with linear algebra
* using eigenvalues for natural frequency calculations
I'm open to other suggestions. These are some of the applications that I have current students doing in engineering work.
My question is: Would these Howto's be appopriate for the "Numpy Tutorials" (https://github.com/numpy/numpytutorials) repo?
My personal opinion is that Howto's are easier to organize and curate (for Numpy) and easier to write (for students).
Best Regards,
Ryan

SciPy 1.5.0 Release Notes
==========================
Note: Scipy 1.5.0 is not released yet!
SciPy 1.5.0 is the culmination of 6 months of hard work. It contains
many new features, numerous bugfixes, 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 bugfixes 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 bugfix 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 64bit integer size from linear algebra
backends
 addition of the probability distribution for twosided onesample
KolmogorovSmirnov 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 quasilinear complexity.
`scipy.cluster.hierarchy.dendrogram` now respects the ``matplotlib`` color
palette
`scipy.fft` improvements

A new keywordonly 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 ``mklfft``), and it is
currently not used in SciPy.
`scipy.integrate` improvements

`scipy.interpolate` improvements

`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
nonnegative 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 KhatriRao
product,
was added.
The new function `scipy.linalg.convolution_matrix` constructs the Toeplitz
matrix representing onedimensional convolution.
`scipy.ndimage` improvements

`scipy.optimize` improvements

The finite difference numerical differentiation used in various ``minimize``
methods that use gradients has several new features:
 2point, 3point, or complex step finite differences can be used.
Previously
only a 2step 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 pivotbased redundancy removal routine and sparse
presolve are faster
 When ``scikitsparse`` is available, solving sparse problems with
``method='interiorpoint'`` 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 nsphere
`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 kdtrees.
`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 gh11069).
`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 oneway ANOVA tests for data stored in ndimensional
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.
3rdparty distributions may need to modify the signature of the ``_rvs()``
method to conform to ``_rvs(self, ..., size=None, random_state=None)``. (A
onetime VisibleDeprecationWarning is emitted when using nonconformant
distributions.)
The KolmogorovSmirnov twosided test statistic distribution
(`scipy.stats.kstwo`) was added. Calculates the distribution of the KS
twosided 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 pvalue 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 pvalue 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 Cythonbased 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 onesample and
twosample testing. The onesample variation uses `scipy.stats.ksone`
(or `scipy.stats.kstwo` with back off to `scipy.stats.kstwobign`) to
calculate
the pvalue. The twosample 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 pvalues, especially for twosample 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
nonnegative
nonintegral ``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.
`scipy.stats` changes

Other changes
=============
Improved support for leveraging 64bit 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.
Early stage adoption of type annotations in a few parts of the codebase

Hi all,
just curious, has anyone reservations about extending the ndarray
struct (and the void scalar one)?
The reason is that, I am starting to dislike the way we handle the
buffer interface.
Due to issues with backward compatibility, we cannot use the "right"
way to free the buffer information. Because of that, the way we solve
it is by storing lists of pointers in a dictionary...
To me this seems a bit complicating, and is annoying since it adds a
dictionary lookup overhead to every single array deletion (and
inserting for every buffer creation). Also, it looks a bit like a
memory leak in some cases (although that probably only annoys me and
only when running valgrind).
It seems that it would be much simpler to tag the bufferinfo on to the
array object itself. Which, however, would require extending the array
object by a single pointer [1].
Extending is in theory an ABI break if anyone subclasses ndarray from C
(extending the struct) and does not very carefully anticipate the
possibility. I am not even sure we support that, but its hard to be
sure...
Cheers,
Sebastian
[1] The size difference should not matter IMO, and with cythons
memoryviews buffers are not an uncommon feature in any case, for the
void scalar it is a bit bigger, but they are also very rare.
(I thought of using weak references, but the CPython API seems not very
fleshed out, or at least not documented, so not sure about that).

The NumPy web team is excited to announce the launch of the newly
redesigned numpy.org. To transform the website into a comprehensive, yet
usercentric, resource of all things NumPy was a primary focus of this
monthslong effort. We thank Joe LaChance, Ralf Gommers, Shaloo Shalini,
Shekhar Prasad Rajak, Ross Barnowski, and Mars Lee for their extensive
contributions to the project.
The new site features a curated collection of NumPy related educational
resources for every user level, an overview of the entire Python scientific
computing ecosystem, and several case studies highlighting the importance
of the library to the many advances in scientific research as well as the
industry in recent years. The “Install” and “Get Help” pages offer advice
on how to find answers to installation and usage questions, while those who
are looking to connect with others within our large and diverse community
will find the “Community” page very helpful.
The new website will be updated on a regular basis with news about the
NumPy project development milestones, community initiatives and events.
Visitors are encouraged to explore the website and sign up for the
newsletter.
Next, the NumPy web team will focus on updating graphics and project
identity (a new logo is coming!), adding an installation widget and
translations, better integrating the project documentation via the new
Sphinx theme, and improving the interactive terminal experience. Also, we
are looking to expand our portfolio of case studies and would appreciate
any assistance in this matter.
Best regards,
Inessa Pawson
NumPy web team
