My python version is 3.6. When I need to install opencv, pip install opencv-pythonwhen I use the command to install it, an error occurs, as shown below:

ERROR: Failed building wheel for opencv-python
Failed to build opencv-python
ERROR: Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly
At first I thought it was a network problem, but I tried several times without success.
The first solution is to use the conda command to install successfully, conda install py-opencv.
Test it, the installation is successful.
After checking the information for a long time, I found that the python version is relatively low. If you install it directly, it is difficult to match the high version of opencv and the low version of python.
Therefore, there is also a solution
Install lower version of opencv:
pip install opencv-python==3.4.9.31
Include opencv-contrib-python:
pip install opencv-contrib-python==3.4.9.31
This can also be installed successfully.
