NotImplementedError when running inference with pretrained checkpoints

Thank you for open-sourcing this project!

I attempted to run inference using the pretrained checkpoints, but encountered the following error:

Traceback (most recent call last):

NotImplementedError

Do I need to modify any configurations or provide additional arguments to enable inference? Any guidance would be greatly appreciated.
