Hi, recently all my pre-trained models undergo this error while loading their tokenizer:
Couldn't instantiate the backend tokenizer from one of: (1) a tokenizers library serialization file, (2) a slow tokenizer instance to convert or (3) an equivalent slow tokenizer class to instantiate and convert. You need to have sentencepiece installed to convert a slow tokenizer to a fast one.
I tried to pip install sentencepiece but this does not solve the problem. Do you know any solution? (I am working on Google Colab)
Note: In my humble opinion, changing so important things so fast can generate very dangerous problems. All my students (I teach DL stuff) and clients are stuck on my notebooks. I can understand that after a year a code can become outdated, but not just after two months. This requires a lot of maintenance work from my side!
