Hey @kopyl, I'm having trouble with the notebook -- getting this error when running the last cell:

---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)

      3         input_ids=input_ids,
      4         images=image_tensor,
      5         do_sample=True,

   2771 
   2772             # finished sentences should have their next token be a padding token

RuntimeError: probability tensor contains either `inf`, `nan` or element < 0

Any ideas as to how this can be fixed?

@mshumer try Runpod. Google Colab sometimes has issues.
