【记录】pytorch_transformer使用的一个错误

记录一个错误：
pytorch_transformer使用过程中报错：

Model name '..\chinese_roberta_wwm_ext_pytorch' was not found in model name list (bert-base-uncased, bert-large-uncased, bert-base-cased, bert-large-cased, bert-base-multilingual-uncased, bert-base-multilingual-cased, bert-base-chinese, bert-base-german-cased, bert-large-uncased-whole-word-masking, bert-large-cased-whole-word-masking, bert-large-uncased-whole-word-masking-finetuned-squad, bert-large-cased-whole-word-masking-finetuned-squad, bert-base-cased-finetuned-mrpc). We assumed '..\chinese_roberta_wwm_ext_pytorch' was a path or url but couldn't find any file associated to this path or url.

测试发现，这个预训练模型在window下可以导入，在linux下会报如上的错误；
这是因为你的路径不对，linux下为左斜杠，所以程序把它认作字符串，而非路径；
修改为 ‘…/chinese_roberta_wwm_ext_pytorch’ 就ok了！
