Conda的环境管理

# 创建一个名为ptorch 的环境，指定Python版本是3.6（不用管是3.6.x，conda会为我们自动寻找3.6.x中的最新版本）
conda create --name ptorch python=3.6

# 安装好后，使用activate激活某个环境
#activate ptorch # for Windows

source activate ptorch

# 此时，再次输入
python --version
(ptorch) [root@bhs ~]# python --version
Python 3.6.10 :: Anaconda, Inc.

退出虚拟环境
# deactivate ptorch# for Windows
source deactivate ptorch  # for Linux 

# 删除一个已有的环境
conda remove --name ptorch  --all

Conda的包管理

# 安装pandas
conda install pandas
# conda会从从远程搜索pandas的相关信息和依赖项目，

# 查看已经安装的packages
conda list

conda的一些常用操作

# conda 查看已有环境

[root@bhs ~]# conda info -e

#
base                  *  /root/anaconda3
ptorch                   /root/anaconda3/envs/ptorch
tensorf                  /root/anaconda3/envs/tensorf

# 查看某
个指定环境的已安装包
conda list -n ptorch

# 查找package信息
conda search numpy

# 安装package
conda install -n ptorch numpy


# 更新package
conda update -n ptorch numpy

# 删除package
conda remove -n ptorch numpy
