Error in QA

[whoafridi]

Gives an error in your code that I've tried in recent days! can you give me solution for this ???
Screenshot & error status available below .::

convert the start_token_scores,end_token_scores line of code into two lines as per below

getting start and end scores for answer. Converting input arrays to torch tensors before passing to the model

start_token_scores = model(torch.tensor([input_ids]), token_type_ids=torch.tensor([segment_ids]) )[0]
end_token_scores = model(torch.tensor([input_ids]), token_type_ids=torch.tensor([segment_ids]) )[1]

and run the same will give expected output

Yes it works. Is the error for the new transformers updated package?

[Degananda264]

yeah might be
