Question

I am trying to install pytorch with pip using

pip install torch

or

pip3 install torch===1.3.1 torchvision===0.4.2 -f https://download.pytorch.org/whl/torch_stable.html

with python 3.7.4

and with python 3.8 (latest stable release)

both on 32 and 64 bit.

and getting

I had the same problem. Now the problem is fixed. (2020-05-31)

Visited the site pytorch.org
and find "QUICK START LOCALLY" on homepage of pytorch.org. ( it' can find by scroll down little )
Checking the environment form of your system (ex: Windows, pip, python, ,,) then, you can see the install command. "pip install torch===.... "
Copy the install command
and Execute the command at your system.

Good Luck !!

Use the below commands if you have no GPU (only for CPU):

version 1.2: conda install pytorch==1.2.0 torchvision==0.4.0 cpuonly -c pytorch
for new version: conda install pytorch torchvision cpuonly -c pytorch

or

Use the below commands if you have GPU(use your own CUDA version):

version 1.2: conda install pytorch==1.2.0 torchvision==0.4.0 cudatoolkit=10.0 -c pytorch
for new version: conda install pytorch torchvision cudatoolkit=10.1 -c pytorch

it might be better to use anaconda command prompt for install pytorch and if possible use python 3.6. its more suitable. python 3.6 is more stable for using open source libraries. Also you can find installing process in below link if needed, https://medium.com/@bryant.kou/how-to-install-pytorch-on-windows-step-by-step-cc4d004adb2a

if you need to setup these with pip only, you may try it

for python 3.6:

pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp36-cp36m- win_amd64.whl
pip install torchvision

for python 3.7:

pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp37-cp37m-win_amd64.whl
pip install torchvision

i think Conda is better option instead of pip in open source libraries installation

If you are using Anaconda (3.7) in windows then you need to install via .whl file.

Download .whl file from here:- https://download.pytorch.org/whl/torch_stable.html

then put in the working directory and install it using pip, for my system I have renamed anaconda's pip to pip37

pip37 install torch-1.5.1+cpu-cp37-cp37m-win_amd64.whl
pip37 install torchvision-0.6.1+cpu-cp37-cp37m-win_amd64.whl

It will install Torch 1.5 & Torchvision 0.6.1 in your anaconda environment
