where should i locate video

[yuyonod]

Hello, I'm very naive to computer science(also english) but can i ask you to where (which directory) should I locate to video to annotate???
I got an error below with run example.py
RuntimeError: Given input size: (1536x5x5). Calculated output size: (1536x0x0). Output size is too small

It is probably coming because I did'nt edit comments you meant that

# raw_targets contains the detections for each video of the batch
# raw_targets = [[[class, t_start, t_end] for (class, t_start, t_end) in video.metadata] for video in batch]
# where t_start, t_end are in [0, 1] (normalized by the sample_duration)

Could you tell me how should I add video and how should I edits comments those. Thank you for your kind and nice work in anyway!
