Answer 1

Warning: Unless you have a very specific reason not to, just follow the official installation instructions from https://pytorch.org. They are far more likely to be accurate and up-to-date.

Here is how to install the PyTorch package from the official channel, on Windows using Anaconda, as of the time of writing this comment (31/03/2020):

PyTorch without CUDA:

conda install pytorch torchvision cpuonly -c pytorch

PyTorch with CUDA 10.1:

conda install pytorch torchvision cudatoolkit=10.1 -c pytorch

Answer 2

go to the official website: http://pytorch.org/

1. Select Windows as your operating system
2. Select your Package Manager such as pip or conda
3. Select you python version
4. Select CUDA or choose none You will get the command that will install pytorch on your system based on your selection.

For example, if you choose Windows, pip, python 3.6 and none in the listed steps, you will get the following commands:

pip3 install http://download.pytorch.org/whl/cpu/torch-0.4.0-cp36-cp36m-win_amd64.whl 
pip3 install torchvision

Answer 3

If you are trying to install on windows 10 and you are not having the anaconda installation than the best options are below:

Python 2.7

pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp27-cp27mu-linux_x86_64.whl
pip install torchvision

If the above command does not work, then you have python 2.7 UCS2, use this command

pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp27-cp27m-linux_x86_64.whl

Python 3.5

pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp35-cp35m-win_amd64.whl
pip3 install torchvision

Python 3.6

pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp36-cp36m-win_amd64.whl
pip3 install torchvision

Python 3.7

pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp37-cp37m-win_amd64.whl
pip3 install torchvision

Best way is to check on the official website for up-to-date options. Here are the ones working as of 2020-03:

# for windows 10, CUDA 10.1
conda install pytorch torchvision cudatoolkit=10.1 -c pytorch

#for windows 10, CUDA 9
conda install pytorch torchvision cudatoolkit=9.2 -c pytorch -c defaults -c numba/label/dev

It seems that the author (peterjc123) released 2 days ago conda packages to install PyTorch 0.3.0 on windows. Here is a copy:

# for Windows 10 and Windows Server 2016, CUDA 8
conda install -c peterjc123 pytorch cuda80

# for Windows 10 and Windows Server 2016, CUDA 9
conda install -c peterjc123 pytorch cuda90

# for Windows 7/8/8.1 and Windows Server 2008/2012, CUDA 8
conda install -c peterjc123 pytorch_legacy cuda80
