where can I find document about BertPreTrainedModel?
hello,

I am trying to find document about BertPreTrainedModel which is used on colbertv1
I only found the source code below site ( 4.11.3 bert_modeling )
https://huggingface.co/transformers/v3.5.1/_modules/transformers/modeling_bert.html

but I didn't find any document for this in the official site for latest version
https://huggingface.co/

So, My question is **where can I find document about BertPreTrainedModel? is this removed?**
What are you trying to do with `BertPreTrainedModel`? This is an abstract class that isn't really public facing.<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.
