The error is shown in the screenshot. I'm new for the hydra and I just want to run a sample demo (metaworld and dm_control env are ok)

Hey @emigmo ! Thanks for raising this issue. It seems some config files were missing. I have added them here. Could you please try from this branch. Once you confirm that this works, I will merge the PR.

Thank you for adding the config files. And this solves part of the problem of running experiments.
But run the same script to raise the new question:

It look like the pymongo package problem?
And in my conda env, pymongo==3.11.2

Could you try again and pull from https://github.com/facebookresearch/mtrl/tree/fix-iss-1 . I updated the configs.

[emigmo]

Great, it works.
