raise ImportError(err)
ImportError: Bad git executable.
The git executable must be specified in one of the following ways:
- be included in your $PATH
- be set via $GIT_PYTHON_GIT_EXECUTABLE
- explicitly set via git.refresh(<full-path-to-git-executable>)
All git commands will error until this is rectified.
This initial message can be silenced or aggravated in the future by setting the
$GIT_PYTHON_REFRESH environment variable. Use one of the following values:
- quiet|q|silence|s|silent|none|n|0: for no message or exception
- warn|w|warning|log|l|1: for a warning message (logging level CRITICAL, displayed by default)
- error|e|exception|raise|r|2: for a raised exception
Example:
export GIT_PYTHON_REFRESH=quiet

下载并安装 Git：
下面是其官网：https://git-scm.com/download/win
点击画圈圈的Click here download，进行下载git
安装完git后，重启终端（CMD / PowerShell）再运行：输入git --version出现相应的版本号说明安装成功。
git --version
# 应输出：git version 2.x.x出现下面情况就是安装成功。
然后输入指令：
python train.py就不会报错了。
