T5 Model Cards
Author: sshleifer
Pull request: yes
Labels: name: model card

All are identical.
Happy to update w more info!
I didn't have task tags because they seem to already work.

Comments:
The file paths aren't correct. (we have a "legacy" format for non-namespaced models – model pages link to the correct paths)

In fact if you look at the model pages, e.g. https://huggingface.co/t5-base – they already have (non-textual) model cards. Can you update those? Thanks=)

Up, @sshleifer
