@amyeroberts i have changed the inline-documentation in the following files:

1. modeling_vision_encoder_decoder.py
2. modeling_trocr.py

I am not sure if the change in modeling_git.py would be helpful or not, so please do look into that, and if there are other files that require the same change, if i am correct, most of the files that start with "modeling_" have the documentation, should i apply the changes to those too ? I have not changed other files, since it seems that might caues some functionalities to break

[amyeroberts]

Thanks for working on this!

No need to make changes in other modeling files - this fix is specific to TrOCR
