Comment (by Gabriele Bozzola):

Hi Roland, I didn’t act quickly enough and the invitation expired. Can you send another one?

> Having said that: the commit seems to indicate that “numpy” fails, so you are using numpy in your rpar files?

Yes, that is correct.

> The pull request also adds a line

```
OPENBLAS_DIR = /cm/shared/apps/spack/cpu/opt/spack/linux-centos8-zen2/gcc-10.2.0/openblas-0.3.10-3lzjcwjsyu3qmott7k3k52mtzljioax3/
```

> to the option list which seems to go beyond the stated goal of fixing some issue with Python, at least at first glance. Adding it \(assuming that this is the correct path for the loaded module\) is the correct thing to do, but ideally should be done in a separate commit \(no stealth changes with subject lines “[whiterabbit.](http://whiterabbit.com/)exe” please\).

NumPy is compiled against OpenBlas, which has to be loaded to correctly use the package. The line ensures that OpenBlas is consistent within the environment \(ie, NumPy and Einstein Toolkit use the same OpenBlas, as it is provided by the module\). I agree that this a little bit beyond the scope of the commit, also because there is no need for NumPy and Einstein Toolkit to use the same OpenBlas. 

‌

In general, following the discussion in the mailing list \([http://lists.einsteintoolkit.org/pipermail/users/2021-August/008179.html](http://lists.einsteintoolkit.org/pipermail/users/2021-August/008179.html)\), it is likely that this entry for Expanse is not the best one. I am waiting to see if the admins do anything about their ucx/verbs stack.
