  • I do not see a specific error message
  • Stop opening a new thread for the same problem over and over again
  1. yeah . that is the problem for me . how i can find it ?
  2. sorry for that .
  • there must be a clear error message in the log
  • the suggestions I made in the other thread were not implemented

Thanks for your prompt response. i tried your other suggestions .

removing OpenCV-python
Delete the environment.yml file.
Delete the requirements.txt file and write it from scratch manually and include only those python libraries you actually use in your python code.

after some random errors, finally it worked .

but the new problem is, my streamlit camera not open properly and after some seconds . i got this below error

During handling of the above exception, another exception occurred:
