This is definitely an MPI issue, and probably unrelated to pyoptsparse. As you say you are not using MPI, you could try to run pyoptsparse without MPI support. This should be possible by removing the mpi4py package from your environment (see https://mdolab-pyoptsparse.readthedocs-hosted.com/en/latest/advancedFeatures.html#mpi-handling)
from pyoptsparse.

Hello @alicebain, I agree with Phil, this looks related to MPI and I bet you will have the same issues if you directly import mpi4py. Setting the PYOPTSPARSE_REQUIRE_MPI flag as suggested in the linked documentation above (e.g. export PYOPTSPARSE_REQUIRE_MPI="no" ) is the recommended approach to deal with this.
Let us know if you are still encountering issues.
