python如何安装torch_如何在python2.7中安装pytorch？

我在虚拟环境中使用python2.7。我试图在python2.7中安装Pythorch&＃xff0c;但出现以下错误&＃xff1a;

UnsatisfiableError: The following specifications were found

to be incompatible with the existing python installation in your environment:

- pytorch-cpu -> python[version&＃61;&＃39;3.5.*|3.6.*&＃39;]

- pytorch-cpu -> python[version&＃61;&＃39;>&＃61;3.5,<3.6.0a0|>&＃61;3.6,<3.7.0a0|>&＃61;3.7,<3.8.0a0&＃39;]

If python is on the left-most side of the chain, that&＃39;s the version you&＃39;ve asked for.

When python appears to the right, that indicates that the thing on the left is somehow

not available for the python version you are constrained to. Your current python version

is (python&＃61;2.7). Note that conda will not change your python version to a different minor version

unless you explicitly specify that.

The following specifications were found to be incompatible with each other:
