**A link to original question on Stack Overflow**: 
I am currently trying to figure out how to add an additional classification head to the BertForQA model. I am not sure which is the best / most efficient way to do that. Should I rewrite the source code for BertForQA and inherit from BertPretrainedModel, or should I rather inherit from BertForQA and change the forward pass? The forward pass needs to be fairly similar though... Any help is appreciated!<|||||>This is a matter of taste. I would write my own class which inherits from BertModel but this is completely up to you.<|||||>This issue has been automatically marked as stale because it has not had recent activity.
