Can't install pytorch with pip on Windows

Try installing via .whl file from Christoph Gohlke’s repo at this link: https://www.lfd.uci.edu/~gohlke/pythonlibs/

Make sure you get the right one for your python version (cp37 at the bottom).

Navigate to the file or save it to your working directory, then use

pip3 install path-to-file.whl

Link to .whl file on page

So you have Cuda 10 installed? If you do, try this:

pip3 install https://download.pytorch.org/whl/cu100/torch-1.2.0-cp37-cp37m-win_amd64.whl

followed by:

pip3 install torchvision

To check if it was installed properly, type this into your command line:

python

followed by:

from __future__ import print_function
import torch
x = torch.rand(5, 3)
print(x)

If you get this output:

tensor([[0.3380, 0.3845, 0.3217],
        [0.8337, 0.9050, 0.2650],
        [0.2979, 0.7141, 0.9069],
        [0.1449, 0.1132, 0.1375],
        [0.4675, 0.3947, 0.1426]])

PyTorch was installed correctly!

I had the same issue, and what I noticed is that I was using Python 3.8.1 and the latest PyTorch was for Python 3.7.

I uninstalled Python 3.8.1 and installed 3.7.6 and voila, it worked!

Not sure if this is your case, but it helped me.

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

Please use this, worked out for me.

I tried multiple solutions and it wasn’t working on Windows 10 until I tried this:

pip install torch==1.5.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

If you want your GPU enabled then remove the "+CPU":

pip install torch==1.5.0 -f https://download.pytorch.org/whl/torch_stable.html

PyTorch is now torch.

import torch
print(help("torch"))

try the following in your IDE command prompt then restart the IDE:

conda install pytorch -c pytorch

Go here https://pytorch.org/get-started/previous-versions/ and find the appropriate command for the version you want.

But first it is best to create an virtual environment with the right version of python

conda create -n you_env_name python=?.?.?

Then activate the environment

conda activate your_env_name

it’s because your python version is 32bit while you’re trying to download a 64bit version of Pytorch, navigate to pytorch_whl_page and choose an appreciate version of Pytorch
or reinstall python from the official Python page to a 64bit version

You will find the correct code to run on the PyTorch website.

There, you can choose your OS, platform, pip, conda and other customisation.
For example, the code to install the PyTorch package on Windows using pip and the CUDA 10.2 platform is (without the quotes:

"pip3 install torch==1.9.0+cu102 torchvision==0.10.0+cu102 torchaudio===0.9.0 -f https://download.pytorch.org/whl/torch_stable.html"

Just downgrade your python version. I was using Python 3.10 then I uninstalled that and reinstalled python 3.7. It started working for me

As a fresh try, i ran into the same problem and it took me a long time but i solved at the end of efforts. After I saw this note "Currently, PyTorch on Windows only supports Python 3.8-3.11; Python 2.x is not supported." on https://pytorch.org/get-started/locally the lights flashed. I found 3.10.11 version and downloaded. In Cmd i typed "pip3 install torch torchvision torchaudio –index-url https://download.pytorch.org/whl/cu118" that command which stated on the website. After these steps my problem solved.
I hope it can be useful to those who encounter the same problem.
