How to install CV2 smoothly in Anaconda

I have tried several commands and none of them work. I have installed Anaconda and want to install this cv2.The conda install opencv command can also be used, but it will upgrade packages such as numpy, pandas, etc. I don't want to upgrade these packages.

Finally searched for a method and found a suitable method:

First, enter conda activate your environment name (except base) in the command line interface

Enter the environment you need to install, and then enter the following command:

conda install -c conda-forge opencv

Finally follow the requirements to install successfully!
