Assertion error

[Tortoise17]

HI Zhong.

I have seen your this very nice project.
I am facing one issue.

File "src/scripts/generate_dataview.py", line 251, in
main(sys.argv)
File "src/scripts/generate_dataview.py", line 248, in main
generate_dataview(**varsArgs)
File "src/scripts/generate_dataview.py", line 185, in generate_dataview
assert len(vid_paths) == len(cap_paths) > 0
AssertionError

Can you help me to handle or resolve?
