Hi @tiandiao123, you can check [https://github.com/apache/incubator-tvm/blob/main/python/tvm/driver/tvmc/frontends.py](https://github.com/apache/incubator-tvm/blob/main/python/tvm/driver/tvmc/frontends.py), where all the input formats are dealt with. This is where we discover input shapes - each framework will have it’s own way.
