I see that as of now, some layers useful for NLP models such as embedding, bidrectional, and others are unsupported by TVM’s frontend. I notice that some of them are commented out in _convert_map in frontend files (like in https://github.com/dmlc/tvm/blob/master/python/tvm/relay/frontend/keras.py).
- Is there a reason why these layers are currently unsupported?
- Are there plans or development efforts already underway?
- I was planning to develop these layers anyway. Could anyone briefly explain how those layers could be incorporated into TVM?
Thanks!
