如何在 keras 中绘制类似 plot_model 的模型

Question

如何绘制如下图所示的模型：

Answer 1

您可以使用matrix或chains。这是使用 的版本matrix of nodes。显然，我没有从您的屏幕截图中输入文本。

\documentclass[tikz,border=3mm]{standalone}
\usepackage{multirow}
\usetikzlibrary{arrows.meta,bending,matrix}
\begin{document}
\begin{tikzpicture}[font=\sffamily,>={Latex[bend]}]
 \matrix[matrix of nodes,nodes={anchor=center,inner sep=0pt,outer sep=0pt},
     ampersand replacement=\&,column sep=3em,row sep=1.5em](mat){
