发生异常: ImportError attempted relative import with no known parent package

在Python中，当你使用相对引用方式（例如import ...module）去引用包时，如果没有已知的父包，就会出现ImportError: attempted relative import with no known parent package异常。这个异常的原因是Python解释器无法解析相关模块的相对路径导入。具体来说，当你的脚本中使用了相对导入方法，并且没有明确指定父包，就会触发这个异常。这个异常通常会显示出错的行数，提示你在代码的第几行出现了相对导入问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
