When I use "BertForQuestionAnswering.from_pretrained" to import my pytorch_model.bin, there having a error "tarfile.ReadError: not a gzip file".So, what should I do to use my pytorch_model.bin? Thanks.

Just like these:
Model_path = "../chinese_roberta_wwm_large_ext_pytorch/pytorch_model.bin"
bert_config = BertConfig.from_pretrained(args.config_path, output_hidden_states=False)
tokenizer = BertTokenizer.from_pretrained(args.vocab_path, config=bert_config)
model = BertForQuestionAnswering.from_pretrained(Model_path , config=bert_config)
