Question

我正在尝试在窗口上安装pytorch。

首先，我从here获得命令conda install pytorch torchvision cpuonly -c pytorch

(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.

looking for, navigate to
    https://anaconda.org
and use the search bar at the top of the page.**

然后我还通过命令pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html切换pip安装，然后遇到此错误：

**(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**

我真的不知道如何解决它，请帮助我，非常感谢！

Answer 1

要安装pytorch，请遵循以下两个步骤。

首先运行此命令

C:\Users\User>conda install PyTorch -c PyTorch

然后运行此代码

C:\Users\User>pip3 install torchvision

Answer 2

似乎您可能已经安装了32位Python，在这种情况下，您遇到的问题是：#16633。测试也在该问题上。

请注意，pyTorch doesn't work on 32-bit systems。

请使用Windows和Python 64位版本。

使用conda或pip在Windows上安装conda
