Win10快速离线安装PyTorch(CPU)版

(1)下载安装包：

pytorch-1.4.0-py3.7_cpu_0.tar.bz2

torchvision-0.5.0-py37_cpu.tar.bz2

(2)anaconda安装PyTorch

conda install pytorch-1.4.0-py3.7_cpu_0.tar.bz2

在安装时，可能会报如下错误，可能存在的问题是用户权限不够，本人解决方法为anacoda prompt 采用管理员身份打开，然后再执行上述步骤即可安装成功。

InvalidArchiveError(
"Error with archive C:\\Users\\Ad\\.conda\\pkgs\\paddlepaddle-1.6.1-py37_cpu_windows.tar.bz2.  You probably need to delete and re-download or re-create this file.  Message from libarchive was:\n\nFailed to open 'C:\\Users\\ Ad\\.conda\\pkgs\\paddlepaddle-1.6.1-py37_cpu_windows.tar.bz2'")

(3)anaconda 安装torchvision

conda install torchvision-0.5.0-py37_cpu.tar.bz2

执行过程和存在的问题与(2)相同。

(4)查看是否安装成功，如果能够正常导入，则表示安装成功。
