Folder names inconsistent if version is string and using `TensorBoardLogger`
A) According to TensorBoardLogger, if version is a string then it is used as the run-specific subdirectory name, otherwise 'version_${version}' is used.
B) However,  in the callback 'version_${version}' is always used.

Edit: This issue comes up as I generally use git commit IDs as version numbers.
