python3 quick install pytorch

     Need to install pytorch, but failed after several attempts. At the same time, due to the relatively large size of pytorch, the download speed is also relatively slow. Here is a summary of the quick installation steps of pytorch for future reference and peer reference.

One install Tsinghua mirror

Under the path of your C drive (C:\Users\1112\AppData\Roaming), mainly in AppData\Roaming, the user (1112) may be different for each computer (mine is win10). Then create a new folder pip, as shown below:

 

 

Then create a new text document pip.ini in the pip folder, with the content inside:

[global]
timeout = 6000
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
trusted-host = pypi.tuna.tsinghua.edu.cn

Then save it as a file pip.ini (the format is all formats, not text types, it's easy to make mistakes here)

After success, it will become the configuration file. When installing the package with pip in the future, the Tsinghua mirror is used by default, which is very fast

 

Two install pytouch

Successful practices:

pip install torch==1.2.0+cpu torchvision==0.4.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

 The installation is successful in less than 30 seconds (the benefits of using mirroring)

 

Failure prompt situation:
