YOLOv5实战训练自己的数据集(Windows和Ubuntu演示)

老师，我这里报错，是怎么回事呢Traceback (most recent call last):
File "D:\Anaconda\lib\site-packages\git_init.py", line 89, in

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):

老师，这个github上的标注工具找不到了，请问您能发一个在群里面吗？

电脑上视频播放时，屏幕左上可看到“下载课件”的链接。先下载课件，项目流程的课件中有课程网盘链接，可下载其它课程资料。

按着你的步骤一步步来的，还是出错了，这些问题该怎么解决**

老师您好，我看到您在模型性能统计这里用的是验证集做统计而不是用测试集，请问这个统计结果可以用于论文上吗？验证集在YOLOv5训练的过程中会参与训练吗？
