Are tubelets actually predicted for AVA?

[AlexeyG]

Hello,

Thank you for your excellent work on TubeR. And also for open sourcing the code and the main results.

Looking through the code, it appears that there is a lot of specialisation of the model happening for specific datasets (for example 1, 2, 3).

Most importantly, Figure 5 of the paper suggests that the model predicts tubelets on AVA. But based on the released code, I don't see where this happens.

Specifially, from code it looks like when training on AVA the TubeR model does not actually use tubelet queries (i.e. the query_embed tensor does not have a temporal axis or the temporal_length multiplier). How can TubeR be used to output tubletlet predictions on AVA in this case?

Thank you!
