FileNotFoundError: [Errno 2] No such file or directory: 'data/output/pywork/example/tracks.pckl'

hi guys

I tried to test pipelines when I followed the instructions in the readme.md file but faced with this error.

Traceback (most recent call last):
  File "run_pipeline.py", line 298, in <module>
    scene = scene_detect(opt)
  File "run_pipeline.py", line 235, in scene_detect

    curr_hsv[i] = curr_hsv[i].astype(numpy.int32)
TypeError: 'tuple' object does not support item assignment

FileNotFoundError: [Errno 2] No such file or directory: 'data/output/pywork/clip1/tracks.pckl'

when I checked content_detector.py file (line 92), I realized that the code is like below:

# line 92 content_detector.py
curr_hsv = cv2.split(cv2.cvtColor(frame_img, cv2.COLOR_BGR2HSV))

the cv2.split function takes an image as input and returns its color channels as a tuple. and then:

# line 100 content_detector.py
curr_hsv[i] = curr_hsv[i].astype(numpy.int32)

but as the error said, tuple object is immutable and does not support item assignment. when I cast the first line to list, the problem was fixed.

# fixed
# line 92 content_detector.py
curr_hsv = list(cv2.split(cv2.cvtColor(frame_img, cv2.COLOR_BGR2HSV)))

scenedetecor version that I used, was scenedetect==0.5.1. Is this bug fixed in the new version of scenedetect module? if so, I think requirements.txt needs to be updated.

this can be fixed thorough installing scenedetect from source: https://github.com/Breakthrough/PySceneDetect/archive/refs/tags/v0.5.6.1.tar.gz
