Description ----------- SfePy (simple finite elements in Python) is a software for solving systems of coupled partial differential equations by the finite element method or by the isogeometric analysis (limited support). It is distributed under the new BSD license.

Date: Tue, 9 Jul 2019 18:32:05 +0200 Subject: [SciPy-User] Issues building scipy Message-ID: I am creating this thread to discuss issues i encounter while trying to build scipy Python is a 3.5.2 built from sources Numpy is 1.16.4 built from sources. With MKL 2019 link Scipy is 1.3.0 gfortran is the MINGW64 version 8.1 C compiler is VS2015 First tried platform is win64 / VS2015 First issue i encountered was that gfortran was in a path with spaces, leading to incorrect command lines because the path to gfortran is not quoted. I did junbctions to get a path to the same place without spaces. I still see some paths with spaces inb /LIBPATH: arguments of cl, but strangely that does not seem to bring issues. Next issue seems to be about undefined symbol _dgtsv. Which seems to be a lapack symbol. scipy seems to have found site.cfg of numpy build with mkl config, but the gfortran command line that fails does not have link to mkl libs references in site.cfg. Am i right to think i need to pass extra link flags to mkl to gfortran? How can i do this from setup.py command line or modification of numpy's site.cfg? An other strange thing i see is that prior to launching my build script, i am in a console with environment to find x64 verion of VS2015 build tools. However, the cl command lines use the x86 version of the compiler to cross compile for x64 (...\VC\BIN\x86_amd64\cl.exe). Where does that come from? Numpy distutils?

The 1.17 release contains a number of new features that should substantially improve its performance and usefulness. The Python versions supported are 3.5-3.7, note that Python 2.7 has been dropped. Python 3.8b2 should work with the released source packages, but there are no guarantees about future releases. Highlights of this release are: - A new extensible random module along with four selectable random number generators and improved seeding designed for use in parallel processes has been added. The currently available bit generators are MT19937, PCG64, Philox, and SFC64. - NumPy's FFT implementation was changed from fftpack to pocketfft, resulting in faster, more accurate transforms and better handling of datasets of prime length. - New radix sort and timsort sorting methods. It is currently not possible to choose which will be used, but they are hardwired to the datatype and used when either ``stable`` or ``mergesort`` is passed as the method. - Overriding numpy functions is now possible by default Downstream developers should use Cython >= 0.29.10 for Python 3.8 support and OpenBLAS >= 3.7 (not currently out) to avoid problems on the Skylake architecture. The NumPy wheels on PyPI are built from the OpenBLAS development branch in order to avoid those problems. Wheels for this release can be downloaded from PyPI , source archives and release notes are available from Github . *Contributors* A total of 146 people contributed to this release.
