Hello,
Thank you very much for sharing your precious work with us.
I had two questions regarding the code.

In gma.py, line 60, the query tensor is scaled by self.scale = dim_head ** -0.5. Why is that necessary? I would also be thankful if you explain why you set the value to dim_head ** -0.5.
In the same file, line 113, motion features are added to the attention output tensor. Could you please give some insights on that as well?

Thanks a lot.
Azin
