TikZ 图片未出现在海报中

我正在使用此处提供的模板用 LaTeX 制作海报http://www.damtp.cam.ac.uk/user/eglen/damtp/cuposter/。

由于某种原因，使用 TikZ 创建的图像未出现在海报中。它编译得很好，并且使用添加的其他图像也\includegraphics{}出现了。以下是我认为相关的代码部分。同一段代码以及初始 TikZ 包含和定义在 LNCS 模板中运行良好。如果我可以添加更多信息，请告诉我。

\documentclass[noback]{cuposter}

\usepackage{mathptmx}
\usepackage{xspace}
\usepackage{amsmath}
\usepackage{pifont}
\usepackage{psfrag}
\usepackage{graphicx}
\usepackage{wrapfig}

% Tikz stuff
\usepackage{tikz}
\usetikzlibrary{arrows}
\usetikzlibrary{positioning}
\usetikzlibrary{fit,chains}

\tikzset{latent/.style={circle,fill=white,draw=black,inner sep=1pt, 
minimum size=20pt, font=\fontsize{10}{10}\selectfont},
obs/.style={latent,fill=gray!25},
const/.style={rectangle, inner sep=0pt},
factor/.style={rectangle, fill=black,minimum size=5pt, inner sep=0pt},
>={triangle 45}}

\pgfdeclarelayer{b}
\pgfdeclarelayer{f}
\pgfsetlayers{b,main,f}

% shapename, fitlist, caption, pos
\newcommand{\plate}[4]{
\begin{pgfonlayer}{b}
    \node (invis#1) [draw, color=white, inner sep=2pt,rectangle, fit=#2] {};
\end{pgfonlayer}

\begin{pgfonlayer}{f}
    \node (#1) [draw,inner sep=0pt, rectangle,fit=(invis#1),#3,#4] {};
\end{pgfonlayer}
}

该类cuposter不允许使用诸如figure或 之类的浮动环境table。

删除figure环境后你的图片就会出现。
