更改conda源

conda官方示例清华镜像源

 

 

出现CondaHTTPError: HTTP 000 CONNECTION FAILED for url这个错误，直接重新配置源地址即可

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/linux-64/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/linux-64/
conda config --set show_channel_urls yes

 

查看已添加的源

conda config --show-sources 

==> /home/lhw/.condarc <==

ssl_verify: true

channels:
  - defaults
show_channel_urls: true
default_channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main

添加pytorch

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/msys2/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/menpo/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
 
# 设置搜索时显示通道地址
conda config --set show_channel_urls yes

 

 python更改镜像源

python更改镜像源win10

C:\Users\xx\pip，并新建文件pip.ini文件，pip文件内容如下：
[global]
timeout = 100
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = pypi.tuna.tsinghua.edu.cn

 

cd ~/.pip
如果不存在.pip则创建目录
mkdir ~/.pip
cd ~/.pip


sudo gedit ~/.pip/pip.conf

[global]

timeout = 100
index-url = https://pypi.tuna.tsinghua.edu.cn/simple/ 
[install]
trusted-host = pypi.tuna.tsinghua.edu.cn

 

 

 安装python3.6以下版本时，pip install 出现

ValueError: Unable to determine SOCKS version from socks://127.0.0.1:1089/

解决方案：
printenv | grep all_proxy

    显示：all_proxy=socks://127.0.0.1:1089/

export all_proxy="socks5://127.0.0.1:1089"
