* nits

* fix t5 too

* use assert equal

* fix llama decoding

* nits on t5

* fixup

* only remove the prefix space, not other spaces

* more deconding tests and more todos

* fix CI as well

* fixup

* skip failing test on CI (its tf its ok)

* skip test_subword_regularization_tokenizer that is also crashing on the CI for TF

* update llama

* revert good fixes

* fixup

* empty

* explain why we need to encode with an additional token

* better warning?

* nits
