The prompt tuning example (prompt-tuning-sst2) don't work

Hi, I have tried to run the notebook example you have published (without editing) in colab but it doesn't work... I get the following error:

RuntimeError                              Traceback (most recent call last)

It is probably about the transformers version out of date but petals 1.1.1 requires transformers==4.25.1
