error installing pytorch using pip on windows 10

I am trying to install pytorch with pip using

with python 3.7.4

and with python 3.8 (latest stable release)

both on 32 and 64 bit.

clearly, I am doing something wrong.

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

1. Visited the site pytorch.org
2. 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.

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

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:

for python 3.7:

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

Transferred this issue to pytorch/vision since it has to do with pytorch/vision

seemethere commented Oct 27, 2020

Currently working on this, will have to issue a v0.8.1 to resolve this though.

rsdmse commented Oct 27, 2020 •

Thanks for your help. Just wanted to check — would it be ok to install the default torchvision 0.8.0 with torch 1.7.0+cu110?
And is there a way to install http://download.pytorch.org/whl/cu110/torchvision-0.8.0-cp37-cp37m-linux_x86_64.whl which seems to be 0.8.0 with CUDA 11?

seemethere commented Oct 27, 2020

Yes you can install with pip install -f https://download.pytorch.org/whl/cu110/torch_stable.html torch==1.7.0+cu110 torchvision==0.8.0

This should be resolved now, you can use:

@seemethere , has this problem reappeared??

It worked for me in the past, but today, no luck.

(I do get a permission denied when I try to go to the download link https://download.pytorch.org/ directly:)

Context:
Working on Windows with Visual Studio Code, Jupyter Notebook, on a Python 3.9.0 based virtualenv.
I import numpy 1.19.3 first (because of fmod bug in Windows), and then try both versions you mention:

I also tried from a terminal inside the virtualenv.

(Related question, I’m on CUDA 11.1, is that OK/backward compatible?)

Can’t install pytorch with pip on Windows

I’m trying to install Pytorch with Windows and I’m using the commands of the official site https://pytorch.org/get-started/locally/

This is the command if I choose Windows, Cuda 10.0, and Python 3.7 But if I run this I get the error message:

So why does this happen? My pip is version 19.2 and I am in a newly installed python 3.7 environment

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

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

The most likely reason for Your issue is a 32-bit installation of python, while the torch libraries rely on having a 64-bit version. I had exactly the same issue.

Just start python from command line and observe

My installation now shows 64 bits. If Yours shows 32, then install 64-bit python. I used this link: Official python 64-bit Windows installer

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

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

If you get this output:

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.

Please use this, worked out for me.

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

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

How to install pytorch in windows?

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:

PyTorch with CUDA 10.1:

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:

Actual answer:

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

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

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

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

Python 3.5

Python 3.6

Python 3.7

Update June 2019: pytorch has a dedicated conda channel now and can be installed easily with anaconda. The command generated at pytorch will require dependencies before it can be executed successfully. For example I chose stable pytorch 1.1 build with python 3.6 and Cuda 10.0. The command generated by pytorch page was as follows:

conda install pytorch torchvision cudatoolkit=10.0 -c pytorch

But it will not work if you have created a new conda environment like me. The step by step process for setting up pytorch is as follows:

• First install the cudatoolkit as follows:

conda install -c anaconda cudatoolkit=10.0

• Then install the mkl_fft as follows:

conda install -c anaconda mkl_fft

• Assuming you will face no more dependency issues. Use the following command to setup pytorch:

conda install -c pytorch pytorch

This worked for me. But I had setup my new conda environment with scikit-learn and jupyter notebook before starting the pytorch setup. So if any dependency problem arise, it would be a good idea to install both scikit-learn and jupyter notebook as well.

vandbt / how to install PyTorch in windows 10

1. Install Python

https://www.python.org/downloads/

2. update pip

python -m pip install —upgrade pip

3. install numpy first

according to PyTorch official guide recommand that install numpy first.

pip install numpy

4. no cuda PyTorch 0.4.1

pip install https://download.pytorch.org/whl/cpu/torch-0.4.1-cp37-cp37m-win_amd64.whl

5. Torchvision

pip install https://download.pytorch.org/whl/torchvision-0.1.6-py3-none-any.whl

I have tried several solutions but still, I cannot install PyTorch locally. I do not want to use Anaconda because it disturbs my existing structure.

I got this error when I tried this solution:

ERROR: torch-0.4.1-cp37-cp37m-win_amd64.whl is not a supported wheel on this platform.

I tried different versions but with the same results, «it is not a supported wheel on this platform».

My environment:
Windows 10 64bit
Python 3.8.2
pip 20.3.1

I suggest you to first degrade your python 3.8.2 to python 3.6.x. (or you can install Anaconda3 version 5.2.0 as python3.6 comes with it).
and then run this command :
pip install https://download.pytorch.org/whl/cpu/torch-0.4.1-cp36-cp36m-win_amd64.whl

(notice that it should be cp36 not cp37 since you’ll be using python3.6.x)

(this worked for me).

You can’t perform that action at this time.
