@noise-field, @sgugger, I think you two are the best set up to review this PR

This looks okay to me, though I'm not an expert in MlFlow.
If the change helps, it would be great to upstream it into the main Transformers repo! :-)

@wamartin-aml this change looks good but if you plan to upstream to transformers repo, I would suggest you make the PR there. We sync with transformers master periodically. So your change will be taken from there anyways.

Ok, will do!
