Hey,

with the environment specified above I cannot reproduce the error.

But I did notice, that h5py is missing in your environment.

So apparently there was some problem with the installation of h5py.

I would suggest you join us at the next [office hours](https://forum.cadet-web.de/t/introducing-office-hours/), next week wednesday.
