Not able to train sequence

[linab8]

Hello! @jbohnslav
I'm just starting to use DeepEthogram, and I was able to train FlowGenerator as well as FeatureExtractor and run inference, but I can't choose the button to train Sequence. I've only imported 5 videos because I want to try out the program before importing all my data. Is there another step to Training Sequence? I've labelled all 5 videos. Also, only these two weights in the picture are shown in the drop down menu although I extracted all 6 of them in the pretrained folder.
Another question - is DeepEthogram suitable for when multiple animals are in the frame? For example, I'll be watching aggression and I need to be able to detect which animal initiated aggression.

Thank you,
Lina
