Not yet.

I removed the compiled \_hermes.so api, and use the Python class SerafinFile instead.

hi [name removed],

did you apply changes to all python scripts?

if so, can you share, please? I’m dealing the same problem.

Up to v8p4, I use Python class SerafinFile, rather than hermes.

The changes that I applied are issues of numpy dtype “np.int” in “data\_manip.formats.serafin\_file” and “data\_manip.extraction.telemac\_file”, which raise errors because it’s been not supported by Numpy.
