5 years ago Update: Assuming that the issues was with the Ubuntu update, I deployed on GCP with a 16.04 Ubuntu VM. The problem persisted, so this is not an OS issue.
I then commented out the single weather epw (Chicago) file and un-commented the the comma separated set of weather files in the .bashrc.
Run appears to be working - but this root cause is puzzling. The IDF has Chicago noted, the README notes the San Francisco, and in practice this only works with the the set of weather files. I am doing this right?
I am running the program without any modifications. I had a successful run right after install, but then undated to Ubuntu 18.0.02 from 18.04.01 and the behavior of the program changed. I have cloned the repo in another directory by following the installation instruction, but the problem persists.
I am running the program with
time python3 -m baselines_energyplus.trpo_mpi.run_energyplus --num-timesteps 10The error file also does not contain much information neither.

I am not certain if the problem is the Ubuntu update or something else.
