1、问题描述：

书籍上的代码例子，执行环境依赖库安装。

pip install -r requirements.txt

发现这句指令有错，pip install git+https://github.com/pytorch/tnt.git@master
安装依赖包torchnet：tnt。遇到如下错误：

PS D:\PycharmProjects\classic> pip install git+https://github.com/pytorch/tnt.git@master

Collecting git+https://github.com/pytorch/tnt.git@master
  Cloning https://github.com/pytorch/tnt.git (to revision master) to c:\users\administrator\appdata\local\temp\pip-req-build-j0h97qgi
  Running command git clone -q https://github.com/pytorch/tnt.git 'C:\Users\Administrator\AppData\Local\Temp\pip-req-build-j0h97qgi'
  ERROR: Error [WinError 2] 系统找不到指定的文件。 while executing command git clone -q https://github.com/pytorch/tnt.git 'C:\Users\Administrator\AppData\Local\Temp\pip-req-build-j0h97qgi'
ERROR: Cannot find command 'git' - do you have 'git' installed and in your PATH?
 

2、解决办法：

1）主要是没有安装git包，执行命令： 

conda install git

2）完成安装git后，再次执行requirements中的指令，完成torchnet包的安装：

pip install git+https://github.com/pytorch/tnt.git@master
