如何在yolov5 python中修复此错误？

问：

我想用数据集训练我的 yolov5，但是当我在 windows 10 命令提示符下运行此命令时，出现此错误：

我运行以下命令（windows 10）：

python train.py --img 415 --batch 16 --epochs 30 --data dataset.yaml --weights yolov5s.pt --cache

命令提示符下出错：

Traceback (most recent call last):
  File "C:\Users\arian\AppData\Local\Programs\Python\Python311\Lib\site-packages\git\__init__.py", line 166, in <module>
    refresh()

    if not Git.refresh(path=path):
           ^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Users\arian\AppData\Local\Programs\Python\Python311\Lib\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:
