列出包和 vbox 警告

我遇到了这么多（见下文）未完全警告，这些警告是由于使用 listing 包和创建代码\begin{lstlisting}\end{}来使代码看起来美观而导致的。有没有什么方法可以修复这些警告？

我正在使用 IEEETran 文档类和lstlisting设置（见下文）。可以调整它来修复问题吗？

\lstset
{
  breaklines=true,
  tabsize=3,
  showstringspaces=false
}


\lstdefinestyle{Common}
{
  extendedchars = \true,
  language = {Python},
  frame = single,
  % ===========================================================                      
  framesep = 3pt,%expand outward.                                                    
  framerule = 0.4pt,%expand outward.                                                 
  xleftmargin = 3.7pt,%make the frame fits in the text area.                         
  xrightmargin = 3.5pt,%make the frame fits in the text area.                        
  % ===========================================================                      
  rulecolor=\color{Red}
}

\lstdefinestyle{B}
{
  style = Common,
  backgroundcolor = \color{Black},
  basicstyle = \scriptsize\color{White}\ttfamily,
  keywordstyle = \color{Orange},
  identifierstyle = \color{Cyan},
  stringstyle = \color{Red},
  commentstyle = \color{Green}
}

列表行之间没有垂直灵活性，因此如果文本高度不是行高的精确倍数（考虑到\topskip第一行使用的高度），那么您将收到此警告（如果您有一整页没有段落分隔符，您也会在普通文本中收到此警告）。

如果您无法更改，您可以在列表之前\textheight使用每个页面底部的选项来增加灵活性。\raggedbottom
