tikz画的图放大后本该重合的线段出现了少量偏移，是否是因为tikz精度的问题，未测试添加对`fpu`的支持后能否解决该问题。   `tikz.tex` ```tex \documentclass[tikz, border=4mm]{standalone} \usepackage{dnnplot} \usetikzlibrary{positioning} \tikzset{ base/.style n args={5}{block={scale=.5, x=#2cm, y=#3cm, z=#4cm, #5}, fill=#1, fill opacity=.5}, Input/.style={base={teal}{.2}{5}{5}{grid={(1,5,5)},#1}}, Kernel/.style={base={cyan}{.2}{3}{3}{grid={(1,3,3)},#1}, fill opacity=1}, Output/.style={base={teal}{.2}{3}{3}{grid={(1,3,3)},#1}}, Cell/.style={base={teal}{.2}{1}{1}{#1}}, } \begin{document} \begin{tikzpicture} \pgfdeclarelayer{background block} \pgfsetlayers{background block, main} \newcommand{\back}[1]{\begin{pgfonlayer}{background block}#1\end{pgfonlayer}} \newlength\xsep \xsep=3.5cm \newlength\ysep \ysep=3.5cm \foreach \i in {0, 1, 2}{ \foreach \j [evaluate=\j as \yin using 5-\j, evaluate=\j as \yout using 3-\j] in {0, 1, 2}{ \begin{scope}[shift={(\i\xsep, -\j\ysep)}] \node[Input] (input) {}; \back{\node[Kernel, anchor=front north west] (k-\i-\j) at (input-x-\i-\yin) {};} \node[Output, right=2cm of input] (output) {}; \back{\node[Cell, anchor=front north west] (o-\i-\j) at (output-x-\i-\yout) {};} \foreach \a/\b in {front south east/front south west, front north east/front north west, back north east/back north west}{ \draw[densely dashed, line width=.2pt] (k-\i-\j.\a) -- (o-\i-\j.\b); } \end{scope} } } \end{tikzpicture} \end{document} ``` 下面是我自己写的包，帮助文档在[https://github.com/ZhiyuanLck/dnnplot](https://github.com/ZhiyuanLck/dnnplot "https://github.com/ZhiyuanLck/dnnplot") dnnplot.zip
