背景

ProxyError: Conda cannot proceed due to an error in your proxy configuration.

使用的是組里的服務器，主要是在創(chuàng)建虛擬環(huán)境以及在已創(chuàng)建的虛擬環(huán)境中使用運行時都出現(xiàn)了同樣的ProxyError，主要是因為conda沒法處理代理，因此得要用戶手動修改**.condarc**文件。一共分為兩步

ProxyError: Conda cannot proceed due to an error in your proxy configuration.
Check for typos and other configuration errors in any '.netrc' file in your home directory,
any environment variables ending in '_PROXY', and any other system-wide proxy configuration settings.

1: 創(chuàng)建環(huán)境時出現(xiàn)ProxyError

~$ conda create -n nn
Collecting package metadata (current_repodata.json): failed

ProxyError: Conda cannot proceed due to an error in your proxy configuration.
Check for typos and other configuration errors in any '.netrc' file in your home directory,
any environment variables ending in '_PROXY', and any other system-wide proxy
configuration settings.

解決方案

首先進入**.condarc**文件，通常為空

~$ vim .condarc

這里對**.condarc**的修改如下:

channels:
  - defaults
show_channel_urls: true
default_channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:
  conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  msys2: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  bioconda: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  menpo: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  pytorch: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  pytorch-lts: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

之后conda可以創(chuàng)建虛擬環(huán)境，本以為一切ok準備安裝一些依賴包的時候，ProxyError再次出現(xiàn)。

2：安裝依賴時出現(xiàn)ProxyError

安裝pytorch時錯誤再次出現(xiàn)

~$ conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch
Collecting package metadata (current_repodata.json): failed

ProxyError: Conda cannot proceed due to an error in your proxy configuration.
Check for typos and other configuration errors in any '.netrc' file in your home directory,
any environment variables ending in '_PROXY', and any other system-wide proxy
configuration settings.

解決方案：

同樣是對**.condarc**文件進行修改，首先查看自己的代理ip

~$ echo $http_proxy
http://...

復制打印出的代理ip地址并添加到**.condarc**配置文件中。(地址都是http，不是https)

proxy_servers:
  http: http://...
  https: http://...
ssl_verify: False

以上就是服務器安裝conda環(huán)境遇到代理PROXY問題及解決方案的詳細內(nèi)容，更多關于服務器安裝conda PROXY的資料請關注腳本之家其它相關文章！
