• Blue Waters Notice: Updates to bwpy Python module

  Created by: gbauer 2018-03-30 17:25:09 (Channels: softwareupdate)

  The Blue Waters Python module, bwpy, has just received a major update.

  • The default python has been changed from python2 to python3. All scripts which are not compatible with both major versions should explicitly use python2 or python3. See https://python3statement.org/ for information on major package developer support timelines.
  • The pypy and pypy3 interpreters are now able to support numpy, scipy, and mpi4py. Some codes may benefit from the jit compilation these interpreters provide.
  • Tensorflow has been updated from 1.3.0 to 1.4.1
  • Python3.6 has been added as the non-default python3 compiler. As not all modules supported by 3.5 are installed for it, Python3.5 remains the default.
  • Numpy, scipy, and other modules which use BLAS routines now use Intel MKL rather than Cray libsci. DO NOT LET PIP INSTALL UPDATES TO THESE MODULES. The OpenBLAS versions installed by pip are significantly slower. Check your ~/.local/lib/*/site-packages and your virtualenvs and delete any versions pip installed. When using pip `install`, it is recommended to use `--upgrade-strategy only-if-needed`
  • A note on virtualenvs: When a virtualenv is created, the version is written into the wrapper script according to the BWPY_VERSION environment variable. If created using bwpy/latest-stable, the virtualenv will always use the "default" image. If created using bwpy/1.1.0, it will always load the 1.1.0 image. This value can be manually changed by editing the wrapper script [virtualenv]/bin/python.
