在利用深度学习服务器，利用Xshell进入端口，想要运行深度学习项目时碰到了以下错误：

Traceback (most recent call last):
  File "/opt/conda/envs/[yolov5_SE]/lib/python3.9/site-packages/git/__init__.py", line 166, in <module>
    refresh()
  File "/opt/conda/envs/[yolov5_SE]/lib/python3.9/site-packages/git/__init__.py", line 153, in refresh
    if not Git.refresh(path=path):
  File "/opt/conda/envs/[yolov5_SE]/lib/python3.9/site-packages/git/cmd.py", line 391, in refresh
    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()

All git commands will error until this is rectified.

This initial warning 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|none|n|0: for no warning or exception
    - warn|w|warning|1: for a printed warning
    - error|e|raise|r|2: for a raised exception

Example:
    export GIT_PYTHON_REFRESH=quiet
The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/root/yolov5-master/yolov5-master/train.py", line 73, in <module>

这个错误表明你的环境中存在与git可执行文件相关的问题。错误提示你需要通过以下方式之一指定git可执行文件的位置：

1. 包含在你的PATH中
2. 通过GIT_PYTHON_GIT_EXECUTABLE设置
3. 通过git.refresh()显式设置

你可以通过以下方法解决这个问题：

1. 确保git可执行文件在系统的PATH中。你可以在终端中运行 git --version 来检查git是否安装。如果没有安装，你需要先安装git。

2. 将GIT_PYTHON_GIT_EXECUTABLE环境变量设置为git可执行文件的路径。

3. 通过代码使用git.refresh()来显式设置git可执行文件的路径。

最终我通过输入以下命令即可完美解决。

export GIT_PYTHON_REFRESH=quiet
