TikZ：如何绘制以下缺失的部分？

我开始学习 TikZ，我的目标是绘制下面的图像。

目标

到目前为止我使用以下代码得到的结果：

\usepackage{tikz}
\usetikzlibrary{shapes.geometric}
\usetikzlibrary{shapes.arrows}

    fill=emb_color, text width=10em, text centered,
    rounded corners, minimum height=2em },

您能帮我理解如何添加缺失的“N x”以及如何插入缺失的 Word、Position 和 Type 框吗？另外，如果您有关于如何改进代码等的建议，我将不胜感激。谢谢。

因此，为了不是为了重写所有内容，我决定保留您的原始结构，即使我认为节点矩阵不是最合适的方法。
我使用了fit，backgrounds当然还有positionning库。

不管你怎么称呼它

有很多事情可以改进，但你肯定走在学习 Ti 的正确道路上钾Z.欢迎加入俱乐部！

答案2

  • 循环起始点必须定义为坐标或具有零的节点inner sep。
  • 您的流程图结构简单：所有节点和坐标都在单链中，因此您可以考虑使用 Ti钾Z 库backgrounds，chains，fit并positioning在绘制它时：
\documentclass[border=3.141592]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,
                backgrounds,
                chains,
                fit,
                positioning,
                shapes.geometric}
\makeatletter
\tikzset{suppress join/.code={\def\tikz@after@path{}}}
\makeatother

\begin{document}
    \begin{tikzpicture}[
node distance = 4mm and 8mm,
  start chain = A going below,
   arr/.style = {Straight Barb-}, 
   box/.style = {draw, rounded corners, semithick, fill=#1,
                 text width=10em, text depth=0.5ex, align=center,
                 inner sep=1ex},
   FIT/.style = {box=gray!10, inner xsep=2em, fit=#1}
                       ]     
% nodes
    \begin{scope}[nodes={on chain=A, join=by arr}]      
\node   {Output};                                   % A-1
\node [box=olive!30]        {Output Projection};    
\node [box=gray!15!blue!15] {Dense}; 
\node [box=yellow!30]       {Add \& Normalize};     % A-4
\node [box=cyan!30]         {Feed Forward};         % A-5
\coordinate (aux1);                                 %  A-6
\node [box=yellow!30,
       suppress join]       {Add \& Normalize};     % A-7
\node [box=orange=30, 
       inner ysep=3ex]      {Fourier};              % A-8

    \end{scope}
% background node
\scoped[on background layer]
    \node[FIT=(A-4) (A-9)] {};
% connections not considered in join macro
\draw   (A-10) -- (aux2)
        (A-7)  -- (aux1);
\draw[arr] (A-4) -|  ([xshift=-1em] A-5.west) |- (aux1);
\draw[arr] (A-7) -|  ([xshift=-1em] A-8.west) |- (aux2);
