python crash on load of certain packages

Starting today I realized that the py3_std.yml that comes with this script does not work anymore, and leads to the following crash when doing a fresh install from scratch:

(py3_std) [swahl@science01 swahl]$ python
Python 3.6.7 | packaged by conda-forge | (default, Feb 28 2019, 09:07:38)
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
Ungültiger Maschinenbefehl (Speicherabzug geschrieben)

Installing openblas=0.3.4 cures the problem. The root cause seems to be related to the CPU feature detection not working properly anymore on virtual machines such as science0x.geomar.de. For more info see https://github.com/conda-forge/openblas-feedstock/issues/60

I'll modify remote_jupyter_manager.sh and add a special .yml for the science0x machines.
