Questions on I3D Two Steam (RGB+Flow) implementation

Hi Team,

Thanks for sharing the great work.

I have the following questions regarding the implementation:

- Have you considered two-stream I3D networks with the flow in your comparison with SlowFast? I can only see that we can use only rgb images with no 2nd steam implementation for Flow images.
- If FLAIR has compared with flow, what was the flow algorithm you used? Plus, how can we integrate the same in the current repository?
- If we haven't compared the results with two-stream I3d due to some reasons. how will the results look like if I integrate two steam I3D + NLN?

Thanks!
