Trouble installing mpi4py

[Donghan Wang]

Hi George,

I have good experience using Conda to handle dependencies. In this case,
you can do:

. /opt/miniconda3/etc/profile.d/conda.s # enable conda
 conda create --name mpi4py python=3.6 # create a new env, namely mpi4py
 conda activate mpi4py
 conda install mpi4py
 pip install tensorflow # or pip install tensorflow-gpu
 git clone https://github.com/openai/baselines.git
 cd baselines
 pip install -e .

 # optionally test the installation
 pip install pytest pandas matplotlib gym[atari]
 pytest

Hope it helps.

Thanks,
Jarod
