![TIKZ 图片命名和引用](https://linux22.com/image/456364/TIKZ%20%E5%9B%BE%E7%89%87%E5%91%BD%E5%90%8D%E5%92%8C%E5%BC%95%E7%94%A8.png)
使用 tikz3.0 时pic
,引用图片的名称时出现错误。编译器显示:
Package pgf Error: No shape named `A1' is known.
Package pgf Error: No shape named `A2' is known.
最小工作代码可以在这里看到:
\documentclass[tikz, border=2mm]{standalone}
\usetikzlibrary{positioning, calc}
\begin{document}
\tikzset{
relu/.pic={
\node [draw,rectangle,
color=green,
text=black,
%inner sep=5pt,
%outer sep=-2pt,
minimum width=.7cm,
minimum height=.7cm,
] (relunode) {};
% Coordinate Y-axis
\draw [very thin,color=gray!70] ([yshift=-2pt] relunode.north) -- ([yshift=+2pt] relunode.south);
% Coordinate X-axis
\draw [very thin,color=gray!70] ([yshift=-7pt, xshift=2pt] relunode.west) -- ([yshift=-7pt, xshift=-2pt] relunode.east);
% Relu function
\draw [thin,color=black] ([yshift=-6pt, xshift=2pt] relunode.west) -- ([yshift=-6pt] relunode.center) -- ([yshift=-2pt, xshift=-2pt] relunode.north east);
}
}
\begin{tikzpicture}
\pic (A1) at (0,0) {relu=A1};
\pic (A2) [right of=A1] {relu=A2};
\draw [thin,color=red] (A1) -- (A2);
\end{tikzpicture}
\end{document}
这里的想法是能够使用这些图表,用最少的代码重写来在文档中设计神经网络架构。
答案1
- @Qrrbrbirlbel 在他的评论中说,图片不是一个节点。
- 使用节点代替
pic
。 path picture bounding box
该节点的使用方式relu
为:
\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{arrows.meta,
positioning}
\newcommand\ppbb{path picture bounding box} % for shorter code
\begin{document}
\begin{tikzpicture}[
node distance = 10mm,
arr/.style = {-{Straight Barb[scale=0.33]}, very thin, gray,
shorten <=2pt, shorten >=2pt},
relu/.style = {draw=green, minimum size=7mm,
path picture={
% Y-axis
\draw[arr] (\ppbb.south) edge (\ppbb.north);
% X-axis
\draw[arr] ([yshift=-7pt] \ppbb.west) -- ([yshift=-7pt] \ppbb.east);
% function
\draw[black] ([shift={(2pt,-6pt)}] \ppbb.west) -- ([yshift=-6pt] \ppbb.center)
-- ([shift={(-2pt,6pt)}] \ppbb.east);
}, % end of path picture /node content/
node contents={}}
]
\node (A1) [relu];
\node (A2) [relu, right=of A1];
\path [draw=red] (A1) -- (A2);
\end{tikzpicture}
\end{document}
