使用 conda 或 pip 在 Windows 上安装 conda

Question

I am trying to install pytorch on my window.

First, I get command conda install pytorch torchvision cpuonly -c pytorch from here

(PyTorch Build:Stable(1.3);Your OS:Windows;Package:Conda;Language:Python3.6;CUDA:None), there are some problems described as followings:
**(python36) C:\Users\li_dan0109>conda install pytorch torchvision cpuonly -c pytorch
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

To search for alternate channels that may provide the conda package you're
looking for, navigate to
    https://anaconda.org
and use the search bar at the top of the page.**

Then I also switch pip install by the command pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html Then I met this error:

**(python36) C:\Users\li_dan0109>pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html
Looking in links: https://download.pytorch.org/whl/torch_stable.html
ERROR: Could not find a version that satisfies the requirement torch==1.3.1+cpu (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch==1.3.1+cpu**

I really don't know how to fix it, please help me and thank you very much!

To install pytorch follow these two steps.

Answer 2

It looks as though you may have the 32-bit installation of Python, in which case you're issue is this: #16633 .

Just be aware, that pyTorch doesn't work on 32-bit systems .

Please use Windows and Python 64-bit version.
