Collecting opencv-python Downloading opencv_python-4.7.0.72-cp37-abi3-win_amd64.whl (38.2 MB)

It looks like you are trying to install OpenCV-Python library in Python 3.7 on a Windows machine. The version you are downloading is 4.7.0.72 which is the latest stable version of the library.

You can use the following command to install the library:

pip install opencv-python

This will download and install the library along with its dependencies. Make sure that you have the latest version of pip installed on your system before running this command.

conda install opencv-python Collecting package metadata (current_repodata.json): done

根据提供的引用内容，当使用conda安装包时，可能会出现"Collecting package metadata (current_repodata.json): failed"的错误。这个错误通常是由于conda无法获取到正确的包元数据导致的。为了解决这个问题，可以尝试更换conda源。

以下是更换conda源的方法：

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes

这些命令将会将conda源更换为清华大学镜像源，这通常可以解决"Collecting package metadata (current_repodata.json): failed"的问题。

现在回答你的问题，当你运行"conda install opencv-python"时，如果之前更换了conda源并且成功配置，那么conda将会尝试从清华大学镜像源中获取并安装"opencv-python"包。

It seems like your conda environment is having trouble installing the `opencv-python` package. One possible solution is to try updating conda and then retry the installation using the following commands:

conda update conda
conda install -c conda-forge opencv

Alternatively, you can also try creating a new conda environment and installing `opencv-python` there. To create a new environment, run:

conda create -n myenv python=3.8

This will create a new environment named `myenv` with Python 3.8 installed. You can activate the environment using:

conda activate myenv

Then, try installing `opencv-python` again using `conda install -c conda-forge opencv`.
