求助opencv安装问题

opencv_python-4.5.3.56-cp37-cp37m-win_amd64.whl这是我下的版本

我直接在anacodna prompt上输入pip install D:\anaconda3\Scripts\opencv_python-4.5.3.56-cp37-cp37m-win_amd64.whl报错：
ERROR: opencv_python-4.5.3.56-cp37-cp37m-win_amd64.whl is not a supported wheel on this platform.

网上面说的查看自己python支持的版本方法：
import pip._internal
>>> print(pip._internal.pep425tags.get_supported())

import pip
>>> print(pip.pep425tags.get_supported())

都没用，全报错AttributeError: module 'pip' has no attribute 'pep425tags'  或者AttributeError: module 'pip._internal' has no attribute 'pep425tags'

我又试了pip3 install opencv-python报错SyntaxError: invalid syntax

求助 怎么查看python支持的版本以及怎么安装成功

电脑不能联网吗？可以联网的话：

pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple

叶夜还

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-python==3.7

在后面限制一下版本号试一试或者直接在pycharm设置——项目——python解释器里边安装包，pycharm不用管那么多，点一下就按好了
