NoneType error occurred when I trained．In my opinion, ｔhe problem lies in the 'train_VID_gt_db.pkl' file. How can I get the 'train_VID_gt_db.pkl' file? Thank ａｎｄ hope for your reply.

Replace root in line 190 with root dataset folder path i.e. 'data'

You can provide a cache path with argument --cache_path
