我正在使用 LaTeX 撰写一些论文，其模板工作正常，但 pdf 输出的每个章节中没有章节编号标签。问题出在哪里？
部分标题如下：
%% ----------------------------------------------------------------
%% Thesis.tex -- MAIN FILE (the one that you compile with LaTeX)
%% ----------------------------------------------------------------
% Set up the document
\documentclass[a4paper, 12pt, oneside]{uet_thesis} % Use the "Thesis" style, based on the ECS Thesis style by Steve Gunn
%\graphicspath{{Figures/}} % Location of the graphics files (set up for graphics to be in PDF format)
% Include any extra LaTeX packages required
\usepackage[square, numbers, comma, sort&compress]{natbib} % Use the "Natbib" style for the references in the Bibliography
\usepackage{verbatim} % Needed for the "comment" environment to make LaTeX comments
%\usepackage{vector} % Allows "\bvec{}" and "\buvec{}" for "blackboard" style bold vectors in maths
\usepackage{url}
%\usepackage{natbib}
\hypersetup{urlcolor=blue, colorlinks=true} % Colours hyperlinks in blue, but this can be distracting if there are many links.
% remove the unnecessary spacing before and after the headings/subheadings
\usepackage[compact]{titlesec}
\titlespacing{\section}{0pt}{*0}{*0}
\titlespacing{\subsection}{0pt}{*0}{*0}
\titlespacing{\subsubsection}{0pt}{*0}{*0}
\setlength{\parskip}{6pt}
%\setlength{\parsep}{0pt}
%\setlength{\headsep}{0pt}
%\setlength{\topskip}{0pt}
%% ----------------------------------------------------------------
\begin{document}
\frontmatter % Begin Roman style (i, ii, iii, iv...) page numbering
% Set up the Title Page
