训练YOLOv5模型遇到的问题及解决办法_all git commands will error until this is rectifie

问题一

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 exception

Example:
export GIT_PYTHON_REFRESH=quiet

解决办法

在train.py文件中的import os后面加上os.environ["GIT_PYTHON_REFRESH"] = "quiet"
如下图：
