Analysis: Do not use the new version of transformers, generally use 3.4.0 or 3.0.2, because of the combination of online comments and my trial , There is no problem with these two.

2. Error loading model:

Remember, after downloading the pre-trained model, you must first change the file name. Otherwise, there will be an error.

3. General routines for model loading:

• When loading the token and model, if it is the tf storage file ckpt, declare from_tf=True.
