Installation des dépendances

gmsh et matplotlib :

pour éviter les problèmes : matplotlib 3.0 et gmsh-sdk (4.2.2.post1)

meshio :

Afin d'éviter des problèmes de compatibilité avec h5, h5py installé avec la commande : HDF5_VERSION=1.10.0 pip install --no-binary=h5py h5py.

Puis installation de meshio : pip install meshio[all].

Remember that pip installs wheels by default. To perform a custom installation with pip, you should use: $ pip install --no-binary=h5py h5py

You can also configure h5py using environment variables. This is handy when installing via pip, as you don’t have direct access to setup.py:

$ HDF5_DIR=/path/to/hdf5 pip install --no-binary=h5py h5py
$ HDF5_VERSION=X.Y.Z pip install --no-binary=h5py h5py
$ CC="mpicc" HDF5_MPI="ON" HDF5_DIR=/path/to/parallel-hdf5 pip install --no-binary=h5py h5py

Pour déterminer la version de h5 installée : dpkg -s libhdf5-dev

Sinon, avec h5py (2.9.0) sans la version adapté à l'installation HDF5 :
