如何使用 TikZ 绘制这样的张量网络？
或许可以添加一些文字。
我对 LaTeX 非常熟悉，但对 TikZ 还是个菜鸟。我会广泛地绘制这些形状，并希望知道它们的模板。谢谢！

这是我目前所做的。我不确定如何在指定边界处连接线，放置节点的正确方法（相对位置还是坐标？），以及如何将标记放在指定位置。
\documentclass[tikz,multi,border=10pt]{standalone}
\usetikzlibrary{shapes.geometric,positioning}
\begin{document}
\begin{tikzpicture}
[
triangle/.style = {regular polygon, regular polygon sides=3, draw=black, fill=green!60!black, inner sep=0pt, minimum size=2cm},
border rotated/.style = {shape border rotate=180},
rectangular/.style={fill=brown!80!black, rectangle, rounded corners = 5pt, draw=black, inner sep=0pt, minimum width=4.5cm, minimum height=1cm},
square/.style={fill=blue!60!black, rectangle, draw=black, inner sep=0pt, minimum size = 1cm}
]
\node[square] (1) {};
\node[triangle, border rotated] (2) [below left = 1cm of 1] {};
\node[triangle, border rotated] (3) [below right = 1cm of 1] {};
\node[rectangular] (4) [below=3cm of 1] {};
\node[square] (7) [below = 7cm of 1]{};
\node[triangle] (5) [above left = 1cm of 7] {};
\node[triangle] (6) [above right = 1cm of 7]{};
\draw (2.35) -- +(0,0.2) -- (1);
\draw (2.145) to [bend right=45] (5.215);
\draw (3.145) -- +(0,0.2) -- (1);
\end{tikzpicture}
\end{document}

我不太确定我是否理解了您问到的所有 3 点。例如，我不确定“token”指的是什么，但我猜是实心的黑色圆圈。
一般来说，相对定位使以后修改代码更加容易。例如，更容易将新内容添加到图表中并让其他内容自动调整。但这实际上是一个在特定情况下哪种方法最有效的问题。通常，绝对定位对于一次性操作来说速度更快，例如，尽管它会使代码的灵活性降低。
我已将其重命名triangle以triangular避免覆盖triangle形状。
下面的代码展示了一种方法：
- 从适当的点连接三角形；
- 将三角形与矩形从适当的点连接起来；
- 在矩形中添加黑色圆圈；
- 添加带有标签的弯曲箭头
s'。
希望这能让您在现有的基础上进一步发展。
