MAC安装pytorch

在机器学习常用的python包anconda下，安装pytorch的步骤非常简答

安装命令：

conda install pytorch torchvision -c pytorch -y

直接一步到位！

 

如果安装过程中，出现下面的连接http时获取URL内容方面的错误时，没关系，再重新运行安装命令，多试几次，相信你总能成功的！

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

验证安装是否成功：

import torch
print(torch.rand(2, 3))

执行后输出类似于：

tensor([[0.6122, 0.4238, 0.0422],
        [0.8809, 0.5974, 0.5142]])

恭喜你安装成功！
