change number of videos in dataset class

[YoniSchirris]

self.number_of_videos = self.sample_data['sample_id'].max()

gives number_of_videos-1

instead, use len(sample_data.index) as given in here

[MalcolmMielle]

Len gives the length of the column right? Since there are multiple lines (one per frame) for each sample number, what we want is the maximum number in the column 'sample_id' hence max(). Maybe add 1 since it's the index and it starts at 0 instead of one. Thus

self.number_of_videos = self.sample_data['sample_id'].max() + 1

[YoniSchirris]

len(self.meta.index) works. but max+1 could also be used

[MalcolmMielle]

Either work :)
