Pytorch selection
The official portal
chooses the installation platform Windows
Package. Generally, those who have installed python know Pip
Language. Life is short. I choose
the version of Python Cuda to view. It is easy to check. Look at the picture below to know from top to bottom, such as my CUDA selection. 10.2
Pip install
pip3 paused. .
When I opened the cmd console and inputted it with great interest, the
pip command alone reported an error. . So I chose to add a 3 after pip, and it did start downloading. . But the download was suspended at 10%. . . . .
At this time, I usually choose to uninstall python and then reinstall it. . . In fact, I did the same. After downloading Python 3.7.9, running pip directly in cmd did not report an error.
Where is the file downloaded? Just curious, you can skip here
This time I am particularly curious about where to download these packages, so a lot of searching, found by this
last conclusion is downloaded to install py Lib's site-packages directory of the file folder below, as shown in Figure
if I do not know Where is py installed? You can run it in the consolewhere python
have a test
from __future__ import print_function
import torch
x = torch.empty(5, 3)
print(x)
If the following things appear after running, it means that everything went well and the installation was successful
tensor([[-5.0307e-28, 5.2549e-43, -5.0307e-28],
[ 5.2549e-43, -5.0302e-28, 5.2549e-43],
