Hi @b.niranjanrao

Are you posting this question in a correct category? Because there is no transformers in NLP Specialization for that week. You posted in:

- Natural Language Processing → NLP with Sequence Models → Week 3 NLP with Sequence Models

Please make sure you post in the right category to get the right people’s attention.

Cheers
