cv2 import error in docker image projectmonai/monailabel:0.4.0

See original GitHub issue

Describe the bug MONAI-Label Server cannot be executed in the current version of the monailabel docker container, because of an opencv import error.

To Reproduce

Run docker container, tag 0.4.0, e.g. via: docker run -it --gpus all --network=host projectmonai/monailabel:0.4.0 bash
Run: python -c "import cv2"

Error message This throws the following error message:

root@workstation:/opt/monai# python -c "import cv2"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/opt/conda/lib/python3.8/site-packages/cv2/__init__.py", line 181, in <module>
    bootstrap()

    if __load_extra_py_code_for_module("cv2", submodule, DEBUG):

    py_module = importlib.import_module(module_name)
  File "/opt/conda/lib/python3.8/importlib/__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "/opt/conda/lib/python3.8/site-packages/cv2/mat_wrapper/__init__.py", line 33, in <module>
    cv._registerMatType(Mat)
AttributeError: partially initialized module 'cv2' has no attribute '_registerMatType' (most likely due to a circular import)

Environment As described above, I am using OOTB docker container projectmonai/monailabel:0.4.0.

Additional information For context, this error does not occur in the current monai-core docker image: projectmonai/monai:0.9.0.

4.6.0.66 has some issue and conflicts with conda (not with regular python) so the current solution is

downgrade opencv-python-headless to previous 4.5.5.64 pip install opencv-python-headless==4.5.5.64

docker run --gpus all --rm -ti --ipc=host --net=host -v ~:/workspace projectmonai/monai:latest bash
python -c "import cv2" # OK

pip install opencv-python-headless
python -c "import cv2" # NOT OK
