Hello there! I have a question regarding the fine-tuning of mbart. I did the training like the example here transformers/examples/pytorch/translation at v4.6.1 · huggingface/transformers · GitHub and obtained a model pytorch_model.bin
However when trying to use the model to translate I get an UnicodeDecodeError UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 64: invalid start byte
The complete error is the following. As far as I can see it produces when loading the model I obtained from fine-tuning.
Traceback (most recent call last):
  File "mbart/predict.py", line 41, in <module>
    main()
  File "mbart/predict.py", line 21, in main
    model = MBartForConditionalGeneration.from_pretrained(opt.model)

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 64: invalid start byte

Any ideas on how to solve this?
Thanks in advance
