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