anaconda3安装，为什么pytorch安装失败

anaconda3安装成功后输入” conda create -n pytorch python=3.6 “就开始报错了

(base) C:\Users\DELL>conda create -n pytorch python=3.6

哪位能帮助在下一下

使用语句 “pip install -i https://mirrors.aliyun.com/pypi/simple/ https://mirrors.aliyun.com/pypi/simple/ 包名”，参考 https://blog.csdn.net/lusing/article/details/104437843 https://blog.csdn.net/lusing/article/details/104437843
