From what I've been able to determine Monitor was removed from gym 0.23.0:

https://github.com/openai/gym/releases/tag/0.23.0

When I pip3 install ./tensorforce it seems to have retrieved gym 0.23.1

Hi @hpcpony, thanks for reporting, that seems to be a recent Gym change and the framework needs to be updated correspondingly. Will do so.

Will do so.

Any way I could help? I would like to try tensorforce, but my environment is fully developed in the 0.25.2 gym version.
