During robustification I get an MPI error.

[HampusAstrom]

I am running the code from https://github.com/uber-research/atari-reset, but since you have not enabled issues there I write here instead.

When I try to run your robustification code with the default parameters from https://github.com/uber-research/go-explore i get the following error:

*** The MPI_Comm_test_inter() function was called before MPI_INIT was invoked.
*** This is disallowed by the MPI standard.
*** Your MPI job will now abort.
[hampusa:2940] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!

I am trying to run it on a single machine, and I have tried if setting --nenvs=1 would help but there is no difference.

I also got the same error in policy_based one. Did you (@HampusAstrom ) find any solutions to this?
