/home/cenvinzf@coria.fr/Desktop/code_saturne_coria-HuuTri_dev/code_saturne/src/mesh/cs_partition.c:2934: Fatal error.
Partitioning with METIS required but neither
ParMETIS nor METIS is available.
Yet, the code has been installed including ParMETIS library, so i can't really figure out what might be causing this issue. Does anybody have a guess?
Looking at your install_saturne.log file, it seems that METIS/ParMetis support was not detected correctly, so you may have an issue in the provided path or a compatibility issue (you would need to check the config.log file in the code_saturne build directory to determine the details).
In any case, you should probably be fine without ParMETIS, using either PT-Scotch or the built-in space-filling curve-based partitioner (with best results usually obtained with PT-Scotch, but this depends on the mesh).
Actually i noticed that this error appears only when i try to run a case which involves the C++ implementation of PyTorch (i'm trying to run an ANN inference inside the code). To test it, i tried to run a case without implementing PyTorch and with the same code configuration, and the error doesn't seem to appear.
Is there a possible conflict between PyTorch and some of Metis dependencies?
I posted the cs_user_script.py file as well to give context.
