Should `track_prev_frame_range` be equal to 1 to reproduce paper's results? #80

Hi. Thank you for sharing your work. I was going through the configuration files, and it seems that track_prev_frame_range is by default set to 5. However, in the paper (as far as I understood) you state that you are only feeding the previous immediate frame (or a few frames further back, in case of augmentation) to the model. Does this mean this value should be set to 1 (or 2) to reproduce your work?

You are mixing up two different concepts. track_prev_frame_range specifies the range from which we sample. but we only sample 1 (or 2 if multi_frame_attention=true) frames. See the track augmentations section for infos regarding the frame range.

Got it! Thanks for the help.
