Thank you for the great work. May I ask you to please describe a bit about how to organise the video frames before running the python gen_dataset_lists.py . I have organised in the following order but it seems not working.

->rawframes(dir)
------>baseball(dir)
---------------->baseball_v1(dir)
-------------------------->img_0001.jpeg(file)
-------------------------->img_0002.jpeg(file)
-------------------------->img_0003.jpeg(file)
-------------------------->img_0004.jpeg(file)
-------------------------->img_0002.jpeg(file)
---------------->baseball_v2(dir)
-------------------------->img_0001.jpeg(file)
-------------------------->img_0002.jpeg(file)
-------------------------->img_0003.jpeg(file)
-------------------------->img_0004.jpeg(file)
------>pushup(dir)
---------------->pushup_v1(dir)
-------------------------->img_0001.jpeg(file)
-------------------------->img_0002.jpeg(file)
-------------------------->img_0003.jpeg(file)
---------------->pushup_v2(dir)
-------------------------->img_0001.jpeg(file)
-------------------------->img_0002.jpeg(file)
-------------------------->img_0003.jpeg(file)

I am passing the following arguments:
"!python gen_dataset_lists.py ucf101 ./rawframes/"

It seems not working. Please help.
