很多小白通过pip安装python包之后，不知道包的位置等详细信息，本文将着手于解决这些问题。

一、切换到指定的python环境

C:\Users\****1>conda info --envs
C:\Users\****1>activate pytorch3.7

C:\Users\****1>conda info --envs
# conda environments:
#
base                  *  D:\ProgramData\Anaconda3
pytorch3.7               D:\ProgramData\Anaconda3\envs\pytorch3.7

C:\Users\****1>activate pytorch3.7

二、列出当前环境下所安装的所有包并对特定包查找
