RCALL_LOGDIR
What is RCALL_LOGDIR supposed to be? I literally cannot find any documentation stating what it's related to anywhere. It's only used in one place, and to print to the terminal, but I'm worried I've screwed up some mpi config (even though I can't find it in the mpi documentation either).
I happened to be looking at the same problem now. Looking at the code and running some experiment, I think you can just supply a random value to that environment variable:
$ RCALL_LOGDIR=/tmp/my_log_dir python -m phasic_policy_gradient.train
Or you can just delete the line in the code. I'm worried that something else (in some C backing a library somewhere) relies on this, and not having it be meaningful is ruining something.
