Alright, I’ll try to switch our pre-commit environment to use python 3.7 as well. Thanks a lot!

@jnissin this behavior (but not the incorrect error message) is expected if you are mixing python3.8 and 3.7 usage within the same repo. See the docs linked by @daavoo, you will need to remove .dvc/tmp/index before running in python 3.7 in this case.
