Hi,

error occurs as using hermes for analyzing serafin file:

_hermes.error is related to b’SERAFIN ’

Hi,

Has this question already been solved ?

This error also occured on my computer :S . My system is Ubuntu 20.04, intel fortran compiler and mpich2 is used.

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.

It should be fixed in V8P5
