Our translation and summarization examples use
None
as a default value fornum_beams
, but this is no longer valid now that we useGenerationConfig
. This PR fixes the examples, and also adds a guard inGenerationConfig
so thatNone
values there are replaced with1
(and a warning is thrown).Also, while I'm fixing example issues, some of our TF examples use
main_process_first
- this is a Torch function, and is not necessary because TF handles distributed training very differently. Since it looks like it could cause problems depending on whether Torch is also present, I'm removing it from all of the TF examples.Fixes #27505
