我试图以这样的图片展示卷积神经网络的各层：
我设法画出了基本的矩形，但是我如何添加像这样的细节呢？
\documentclass[border=5pt, multi, tikz]{standalone}
\usetikzlibrary{quotes,arrows.meta}
\begin{document}
\begin{tikzpicture}[every edge quotes/.append style={auto, text=blue}]
\pgfmathsetmacro{\cubex}{10}
\pgfmathsetmacro{\cubey}{1}
\pgfmathsetmacro{\cubez}{1}
\draw [draw=blue, every edge/.append style={draw=blue, densely dashed, opacity=.5}, fill=none]
(0,0,0) coordinate (o) -- ++(-\cubex,0,0) coordinate (a) -- ++(0,-\cubey,0) coordinate (b) edge coordinate [pos=1] (g) ++(0,0,-\cubez) -- ++(\cubex,0,0) coordinate (c) -- cycle
(o) -- ++(0,0,-\cubez) coordinate (d) -- ++(0,-\cubey,0) coordinate (e) edge (g) -- (c) -- cycle
(o) -- (a) -- ++(0,0,-\cubez) coordinate (f) edge (g) -- (d) -- cycle;
\path [every edge/.append style={draw=blue, |-|}]
(b) +(0,-5pt) coordinate (b1) edge ["500"'] (b1 -| c)
(b) +(-5pt,0) coordinate (b2) (b2 |- a)
(c) +(3.5pt,-3.5pt) coordinate (c2) edge ["1"'] ([xshift=3.5pt,yshift=-3.5pt]e)
;
\end{tikzpicture}

答案1
这是为了给你一个开始。这个答案展示了如何在 3D 中堆叠盒子，以及如何在角落之间绘制连接等等。但是，它不会尝试重现屏幕截图的所有细节。但是，如果您有概念问题，即要求超越重复的功能，我很乐意更新我的答案。
