@sguggerI think it's done! :smiley: , If there is something else,tell me

@osanseviero  I have read and accept the suggestions you make, only few small mistakes that i commented.Thanks a lot for answering so fast!

Hey there! I fixed the 2 suggestions you mentioned :) feel free to commit them now :D 

@osanseviero  @sgugger  everything clear and ok now. Have a nice day! :smile_cat: 

Can you just run `make fix-copies` on your branch to fix the CLI issue? There is probably one or two models out of sync between the READMEs.

I hope now everything is right, sorry for the mistakes :smiling_face_with_tear: 

No worries, looking good now. Thanks again!
