Hi, I just ran this code:
""from transformers import BertTokenizer, BertForQuestionAnswering
modelname = ‘deepset/bert-base-cased-squad2’
tokenizer = BertTokenizer.from_pretrained(modelname)
model = BertForQuestionAnswering.from_pretrained(modelname)""
but I got an error like this:
""OSError: Can’t load weights for ‘deepset/bert-base-cased-squad2’. Make sure that:


‘deepset/bert-base-cased-squad2’ is a correct model identifier listed on ‘Models - Hugging Face’


or ‘deepset/bert-base-cased-squad2’ is the correct path to a directory containing a file named one of pytorch_model.bin, tf_model.h5, model.ckpt.""


I have ensured that those bert-base-cased-squad2 is available, but it still got an error.
Any one know the solution for this problem? Thanks
