@steven-murray The hera_sim errors are happening on this PR too, which just updates documentation.

[mkolopanis]

The error looks like there is no mpi installed, is hera_sim trying to call part of pyuvsim that needs mpi? maybe we need to update our herasim environment?

[bhazelton]

oh, maybe! I think there were other errors besides that on the other PR, but I didn't check this one closely.

[steven-murray]

Yup, looks like it's the MPI requirement. I wonder if it's possible to use hera_sim's own testing env instead of maintaining your own?

[mkolopanis]

just to be safe I rebased after the herasim update.
