opencv版本 不更新一下？ 可以4.5不

[ted8201]

according to official dockerfile, python should use 3.7 version. if you want to use opencv-python==4.5, you can just modify docker/requirements.txt. change opencv-python==3.4.5.20 to opencv-python>=3.4.5.20 like this. however other 3rdparty libraries would still complain, change the requirements.txt accordingly. My suggestion would change python version, that would save you a lot of troubles.
