添加清华源之后仍然提示：HTTP 000 CONNECTION FAILED for url-马春杰杰

有时候按照添加清华源之后，可能仍然会提示：

Solving environment: failed

这主要是因为我们没有把默认的channels删除，按照下面步骤删除即可~

vi ~/.condarc

把defaults这一行删除即可~删除后的.condarc长这样：

channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
