Hey @AmeenBarech
Welcome to the Streamlit Community 
Since you haven’t listed your requirements.txt file so I am not certain about it but the most common fix for this error is replacing opencv-python with opencv-python-headless in the requirements file.
Do let me know if that fixes this issue or please attach some more details about the error.
Best,
Kanak
