AttributeError: type object 'BertConfig' has no attribute 'pretrained_config_archive_map'
Hi,

After changing from `BERT_PRETRAINED_MODEL_ARCHIVE_MAP` to `BERT_PRETRAINED_MODEL_ARCHIVE_LIST` in #5842 , I encountered another issue:

>   File "main.py", line 24, in <genexpr>
>     ALL_MODELS = sum((tuple(conf.pretrained_config_archive_map.keys()) for conf in (BertConfig, XLNetConfig)), ())
> AttributeError: type object 'BertConfig' has no attribute 'pretrained_config_archive_map'

Is it also a breaking change ?
What is the replacing name for `pretrained_config_archive_map` now ?

Thank you,
it'd better to downgrade the version: pip install transformer==2.0.0 (which solves the compatible issue).<|||||>`$ pip install transformers==2.0.0`

works<|||||>Hi, is there any other approach other than downgrading?<|||||>try

or 
`$from transformers import BERT_PRETRAINED_CONFIG_ARCHIVE_MAP`<|||||>Hi! Could you let us know the use cases of using the archive maps?<|||||>
Hi,

I used it to provide the hint of cmd args configuration.<|||||>I see, thank you! The issue is that these archive maps are outdated and don't mean much since the model hub.

In that case, it would be better to have a way to see all checkpoints on the hub corresponding to that model architecture, right?<|||||>If anyone has already solved the issue please let me know. I am having same issue.
