How to produce deterministic episode?

[jmkim0309]

How can I produce fixed, deterministic episode?
Is there any control parameters like random seed to be fixed?

This should already be the case -- the idea behind https://github.com/deepmind/lab/blob/47cd06cd9fb9fe7ce19030ba2a97878356420088/third_party/rl_api/env_c_api.h#L252-L259 is that the provided seed allows reproducing a run, and I think DeepMind Lab tries to be deterministic. Have you found a situation where that doesn't work? Does it involve bots?
