我尝试使用fancyhdr，但不起作用（没有错误，但没有显示标题），可能是因为我使用的模板thesiskiv
\documentclass[czech,BP]{thesiskiv}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\fancyhead[RE]{\leftmark}
\fancyhead[LO]{\rightmark}
\fancyfoot[RO,LE]{\thepage}
\declarationmale
\title{Využítí neuronových sítí\\ v sémantice slov}
\abstracttexten{The text of the abstract (in English). It contains the English translation of the thesis title and a short description of the thesis.}
\usepackage[pdftex]{hyperref}
\hypersetup{colorlinks=true,
unicode=true,
linkcolor=black,
citecolor=black,
urlcolor=black,

\usepackage[numbers,sort&compress]{natbib}
