Error running Callback.ipynb in CI
Locally the examples/Callback.ipynb works, but when running in CI it seems that some samples are missing for the final check:
ValueError: could not broadcast input array from shape (334,) into shape (500,)
see also https://jugit.fz-juelich.de/IBG-1/ModSim/hopsy/-/jobs/407949#L1749 and https://jugit.fz-juelich.de/IBG-1/ModSim/hopsy/-/jobs/407950#L1770.
The input array seems to be randomly missing samples, which means they might not have been completely commited to the databse.
For now we exclude this notebook from the examples-CI because fixing such issues is not part of the issue related to !43 (merged).
@a.stratmann any ideas?
