not able to run PPO in the LunarLander-v2 env

[jramak]

I followed all the instructions here: https://spinningup.openai.com/en/latest/user/installation.html#check-your-install , but I have a problem with mpi4py. I tried the suggestion in stackoverflow (https://stackoverflow.com/questions/35370396/mpi4py-library-not-loaded-usr-local-lib-libmpi-1-dylib), but it does not work for me. Below is the error I'm seeing:

Have you solved it ? I have the similar Error .

Try running this on the command line first:

module load mpi/openmpi-x86_64

I have a macOS. I'm getting module command not found.

If you are out of other options, could you try installing both pip and mpi4py through anaconda?
