Unexpected error while running parlai_chat_task_demo python3 parlai_test_script.py

Question

I receive an error while running an example code from https://github.com/facebookresearch/Mephisto/blob/main/examples/parlai_chat_task_demo/README.md python3 parlai_test_script.py

I try to run an example script. The error:

hydra.errors.ConfigCompositionException: Error merging mephisto/blueprint=parlai_chat

May be someone have already faced the same problem and fixed it? Thank you!

I find an answer! When you install parlai with pip, hydra-core-1.0.7 is a dependency and this old version of package is the reason of my error. You need to install hydra-core-1.1.1.

I hope that it will be useful for somebody.
