YOLOv5运行错误：ImportError: Failed to initialize: Bad git executable.

问题���述：我们在跑YOLOv5官方数据集时，出现这个错误，ImportError: Failed to initialize: Bad git executable.

具体错误如下

ImportError: Failed to initialize: 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 exceptionExample:    export GIT_PYTHON_REFRESH=quiet

具体原因：未知

解决办法：

在train.py文件中的import os后面加上

os.environ["GIT_PYTHON_REFRESH"] = "quiet"

具体位置

import argparseimport mathimport osos.environ["GIT_PYTHON_REFRESH"] = "quiet"import randomimport subprocessimport sysimport timefrom copy import deepcopyfrom datetime import datetimefrom pathlib import Path
