• What did you expect to happen?

When I had installed pytext in the past, I did not get the error portion about PathManager. It has not caused me any issues in training but it might in the future so I wanted to bring this to the developers' attention.

Relevant Code

!pip install --quiet git+https://github.com/facebookresearch/[email protected]
import pytext
