【问题描述】：

我正在尝试在我的窗口上安装 pytorch。

首先，我从here得到命令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.

and use the search bar at the top of the page.**

然后我也通过命令pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html切换pip install 然后遇到这个错误：

**(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**

我真的不知道怎么解决，请帮帮我，非常感谢！

【解决方案2】：

看起来您可能安装了 32 位 Python，在这种情况下，您的问题是：#16633。

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

请使用 Windows 和 Python 64 位版本。
