Users may encounter under-performing MPI jobs or failures of compiling MPI applications if you are using Conda from system. We found pre-installed mpich2 package in some Conda environments overrides default MPI path. The affected Conda packages are
python/3.6-conda5.2. If users experience these issues, please re-load MPI module, e.g.
module load mvapich2/2.3.2 after setting up your Conda environment.
