Hi Magali,

This error indicates that your PYTHONPATH is not set up correctly.

It's possible that your MPI implementation doesn't pass the current 
environment variable to the remote mpi processes. As a result, the 
correct PYTHONPATH is only defined on the host, but not on the compute 
node. You might need to add the above line in your .cshrc.
