BertForSequenceClassification uses [CLS] token's representation to feed a linear classifier. I want to leverage another token (say [X] in the input sequence) rather than [CLS]. What's the most straightforward way to implement that in Transformers?
How to initialize BertForSequenceClassification for different input rather than [CLS] token?

You can define the special tokens when creating the tokenizer.
This is an example of how to modify an special token of a pretrained tokenizer:
Please check the BertTokenizer documentation to see which other special tokens you can modify (
unk_token
,sep_token
,pad_token
,cls_token
,mask_token
, etc.).
