tkz-graph 和 beamer 中标记顶点的问题

请确保下面的代码在文章 Latex 类中完美运行，但是当我尝试将其放入 Beamer 的 IAStheme 中时，标签很奇怪。

代码

    \documentclass[11pt]{beamer}

\usepackage[english,french]{babel}
% or whatever
\usepackage[utf8]{inputenc}
% or whatever

\usepackage{graphicx}
\usepackage{pgf}
\usepackage{pifont}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{xcolor}
\usepackage{colortbl}
\usepackage{tikz}
\usepackage{tkz-graph}
\setbeamertemplate{itemize item}[triangle]
\usetikzlibrary{shapes,topaths,fit,arrows.meta,backgrounds,calc,trees,hobby}
\usetikzlibrary{graphs,graphs.standard}
%\title[Identification In Digraph] % (optional, use only with long paper titles)

\definecolor{myblue}{RGB}{122,163,204}
\begin{document}

\begin{frame}
 \frametitle{Locally transitive}
         
    \begin{tikzpicture}[scale=0.8]
      \SetGraphUnit{2}
      \renewcommand*{\VertexLineColor}{black}
      \renewcommand*{\VertexLightFillColor}{white}
      \renewcommand*{\VertexSmallMinSize}{6pt}
      \renewcommand*{\VertexLineWidth}{1pt}
      %\SetVertexNoLabel
      \GraphInit[vstyle=Welsh]
      \Vertices{circle}{1,2,3,4,5,6,7} % the ... syntax doesn't work here
      \AddVertexColor{myblue}{1,5}
     
      \SetUpEdge[style={->,thick},color=black]
      \foreach \i in {1,...,7}
      { 
        \foreach
        [evaluate=\j as \k using {ifthenelse(Mod(\i+\j,7)==0,int(\i+\j),int(Mod(\i+\j,7)))}]
        \j in {1,2,3}
        { 
        \Edge(\i)(\k)
          }
        }
    
    \end{tikzpicture}
\end{frame}
\end{document}

我不知道如何设置正确的标签（即 1 2 ... 7）

尝试不使用以下内容进行编译babel：

\documentclass[11pt]{beamer}

%\usepackage[english,french]{babel}
% or whatever
\usepackage[utf8]{inputenc}
% or whatever

%\usepackage{graphicx}
\usepackage{pgf}
\usepackage{pifont}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsthm}
%\usepackage{xcolor}
\usepackage{colortbl}
\usepackage{tikz}
\usepackage{tkz-graph}
\setbeamertemplate{itemize item}[triangle]
\usetikzlibrary{shapes,topaths,fit,arrows.meta,backgrounds,calc,trees,hobby}
\usetikzlibrary{graphs,graphs.standard}
%\title[Identification In Digraph] % (optional, use only with long paper titles)

\definecolor{myblue}{RGB}{122,163,204}
\begin{document}

\begin{frame}
 \frametitle{Locally transitive}

    \begin{tikzpicture}[scale=0.8]
      \SetGraphUnit{2}
      \renewcommand*{\VertexLineColor}{black}
      \renewcommand*{\VertexLightFillColor}{white}
      \renewcommand*{\VertexSmallMinSize}{6pt}
      \renewcommand*{\VertexLineWidth}{1pt}
      %\SetVertexNoLabel
      \GraphInit[vstyle=Welsh]
      \Vertices{circle}{1,2,3,4,5,6,7} % the ... syntax doesn't work here
      \AddVertexColor{myblue}{1,5}

      \SetUpEdge[style={->,thick},color=black]
      \foreach \i in {1,...,7}
      { 
        \foreach
        [evaluate=\j as \k using {ifthenelse(Mod(\i+\j,7)==0,int(\i+\j),int(Mod(\i+\j,7)))}]
        \j in {1,2,3}
        { 
        \Edge(\i)(\k)
          }
        }

    \end{tikzpicture}
\end{frame}
\end{document}

编辑： 萨姆卡特找到问题的原因：包babel。更具体地说，原因是french使用选项。它覆盖了一些tikz代码。为了解决这个问题，可以克服这个问题（对于大多数非英语 babel 选项）定义tikzlibrarybabel`。只需将其添加到使用的库中，问题就会解决：

\documentclass{beamer}
\usepackage[english,french]{babel}% <-- this MWE also work with babel

\usepackage{tkz-graph}
\usetikzlibrary{arrows.meta, babel}% <-- added babel library

\usepackage{pifont}
\usepackage{amsmath, amssymb, amsthm}
\usepackage{caption}

\begin{document}
\begin{frame}
\small
    \begin{columns}
\begin{column}{0.45\linewidth}
    \[
\forall~v\in V(T),~deg^-(v)=deg^+(v)
\]
\end{column}
\begin{column}{0.55\linewidth}
    \begin{tikzpicture}
    \SetGraphUnit{2}
    \renewcommand*{\VertexLineColor}{white}
    \renewcommand*{\VertexLightFillColor}{red}
    \renewcommand*{\VertexLineWidth}{1pt}
    \GraphInit[vstyle=Welsh]
    \Vertices{circle}{1,2,3,4,5,6}
    \AddVertexColor{blue}{5,1}
    \SetUpEdge[style={-{Straight Barb[length=1mm,width=1.2mm]}, thick},color=red]
     \foreach \v [count=\vi from 2] in {1,...,5}{
     \foreach \vv in {\vi,...,6}{\Edge(\v)(\vv)};
     };
    \end{tikzpicture}
\end{column}
    \end{columns}
\end{frame}
\end{document}

笔记：不加载已经加载的包beamer（详情请查看beamer文档）。尽可能简化序言。使用 LaTeX 语法来编写方程式。

由于特定beamer主题不（公开）可用，我无法使用您的序言在 MWE 上进行测试。
