Common errors of pytorch installation package (use it yourself, keep recording ~)

1.解决pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool：

Approach: specifying a specific source directly

• Designate Tsinghua source (it seems to be faster, but in the end it still didn't work)

pip --default-timeout=100 install torch -i https://pypi.tuna.tsinghua.edu.cn/simple 

• Specify Douban source (soon, Successfully)

pip --default-timeout=100 install torch -i https://pypi.douban.com/simple
