Remove opencv-python from the req file, you only need the opencv-python-headless package.

I encounter another problem in this application. I opened it today and it asked for reboot, I did the same but I am getting below error. I tried re-deployment as well but it is giving same error. I have not made any changes in my file.

File "/app/all-in-one/elements/selfie_AI/selfie.py", line 2, in <module>

    import cv2

  File "/home/appuser/venv/lib/python3.9/site-packages/cv2/__init__.py", line 181, in <module>

    bootstrap()

  File "/home/appuser/venv/lib/python3.9/site-packages/cv2/__init__.py", line 153, in bootstrap

    native_module = importlib.import_module("cv2")

  File "/usr/local/lib/python3.9/importlib/__init__.py", line 127, in import_module

    return _bootstrap._gcd_import(name[level:], package, level)
