        用conda create -n name python=3.x语句创建新的项目环境时，发现python包不仅下载的慢，还容易报错如上，可以尝试用清华镜像源下载。

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro/

        再重新执行

conda create -n name python=3.x

        这时候会发现不仅下载迅速，而且不会报错。
