Anaconda安装pytorch,torchvision和 cython

在Anaconda Prompt输入conda install pytorch cuda91 -c pytorch

(注意:python2.7 不支持pytorch, 需升级到python3.5以上。

需激活python3.6 环境,输入conda activate 3point6

还需要安装CUDA,这里cuda版本为9.1,这里是window系统)

显示如下:

(3point6) C:\Users\jinlong>conda install pytorch cuda91 -c pytorch

Solving environment: done

==> WARNING: A newer version of conda exists. <==

current version: 4.4.10

latest version: 4.5.4

Please update conda by running

$ conda update -n base conda
