解决torchvision下载报错的方法：OSError: HTTPSConnectionPool(host=‘files.python’错误处理

报错如下:Could not install packages due to an OSError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Max retries exceeded with url: /packages/c0/8f/dfa473f3a6241bff91ae8bb90
5bd0afceb827f37de2917a94b5c4b1112bf/Pillow-9.3.0-cp39-cp39-win_amd64.whl (Caused by ConnectTimeoutError(<pip._vendor.urllib3.connection.HTTPSConnection object at 0x00000259CB4C0760>, 'Con
nection to files.pythonhosted.org timed out. (connect timeout=15)'))

解决办法：命令换成pip install torchvision -i http://pypi.douban.com/simple –trusted-host pypi.douban.com

亲测有效！！！
