Why are these changes needed?
Pytorch Lightning released 2.0 a few weeks ago, and they have changed the import path of
ProgressBarBase
, which could cause an import error if we do not take care of it.Given that PTL has removed all the documentations in 1.x, and many of our users are trying out PTL 2.0, it'd be necessary to ensure compatibility with the latest PTL version in release 2.4. This PR added version check and import
ProgressBarBase
with different paths accordingly.Related issue number
