导出虚拟环境安装文件并在另一台电脑安装

1. 导出Conda虚拟环境

   Linux: conda env export -n my-environment -f my-environment.yml

   my-environment为要导出的虚拟环境的名字，
   并拷贝此安装文件到其他要创建虚拟环境的电脑。

2. 根据Environment.yml安装新的虚拟环境

   Linux: conda env create -f my-environment.yml

   my-environment为从其他电脑导出的虚拟环境包

分享虚拟环境到Anaconda Cloud.

1. 安装Anaconda 客户端

   Linux: conda install anaconda-client

2. 登陆 Cloud 账户

   Linux: anaconda login

   需要首先在 https://anaconda.org/ 创建个人账户。

3. 导出虚拟环境包

   Linux: conda env export -n my-environment -f my-environment.yml

   my-environment为虚拟环境的名字.

4. 上次虚拟环境安装文件到Cloud

   Linux: anaconda upload my-environment.yml

    (cv) frank@gpu-server:~/work$ anaconda upload torch-re-id.yml
    Using Anaconda API: https://api.anaconda.org
    Using "zjcao" as upload username
    Processing 'torch-re-id.yml'
    Detecting file type...
    File type is "env"
    Extracting environment attributes for upload
    Creating package "torch-test"
    Creating release "2019.07.31.105612"
    Uploading file "zjcao/torch-test/2019.07.31.105612/torch-re-id.yml"
    uploaded 7 of 7Kb: 100.00% ETA: 0.0 minutes
    Upload complete
   
    environment located at:
    https://anaconda.org/zjcao/torch-test
   

   Cloud查看: http://envs.anaconda.org/<USERNAME>

5. 其他用户根据云端的虚拟环境安装文件创建新的虚拟环境

   Linux: conda env create user/my-environment

    (cv) frank@gpu-server:~/work$ conda env create zjcao/torch-test
    Collecting package metadata (repodata.json): done
    Solving environment: done
    Preparing transaction: done
    Verifying transaction: done
    Executing transaction: done
    #
    # To activate this environment, use
    #
    #     $ conda activate torch-test
    #
    # To deactivate an active environment, use
    #
    #     $ conda deactivate
   
    (cv) frank@gpu-server:~/work$ conda env list
    # conda environments:
    #
    base                     /home/frank/anaconda3
    cv                    *  /home/frank/anaconda3/envs/cv
    tf                       /home/frank/anaconda3/envs/tf
    torch                    /home/frank/anaconda3/envs/torch
    torch-test               /home/frank/anaconda3/envs/torch-test
   

   注意：没有.yml

6. 激活虚拟环境

   Linux: source activate my-environment
