我在虚拟环境中使用python2.7。我尝试在 python2.7 中安装 pytorch 但出现以下错误:
UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
- pytorch-cpu -> python[version='3.5.*|3.6.*']
- pytorch-cpu -> python[version='>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']
If python is on the left-most side of the chain, that's the version you'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=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:

请帮忙:)
最佳答案
这是 PyTorch official download page 的链接
从这里，您可以根据您的环境和操作系统选择 python 版本(2.7)和 CUDA(无)以及其他相关详细信息。
