I got below error message when I run model_main_tf2.py on Object Detection API:

The weird thing is I run the same code before, it worked well but now it gives me an error.
The same thing occurred to me yesterday when I used Colab. A possible reason may be that the version of opencv-python(4.1.2.30) does not match opencv-python-headless(4.5.5.62). Or the latest version 4.5.5 may have something wrong...
I uninstalled opencv-python-headless==4.5.5.62 and installed 4.1.2.30 and it fixed.
The same thing occurred to me. My status:
C:\Windows\system32>pip list |findstr opencv
opencv-python 4.5.2.52
opencv-python-headless 4.5.5.62
The version isn't same. So I first uninstall headless:
pip uninstall opencv-python-headless==4.5.5.62
Then reinstall headless 4.5.2.52 with opencv-python package.
pip install opencv-python-headless==4.5.2.52
The problem is the resolved.
Try uninstall and install(version 4.1.2.30) Headless main modules package
!pip uninstall opencv-python-headless
!pip install opencv-python-headless==4.1.2.30
