我正在尝试导出晶体的 sagemath 图表（参见以下命令）。
sage: crystals.Tableaux("A3", shape=[2,1]).latex_file("/tmp/a3-21.tex")
我得到如下输出：

但有一个错误，就像
ABD: EveryShipout initializing macros Preview: Fontsize 10pt ! Illegal parameter number in definition of \cmdGR@vertex@L. <to be read again> 1 1.55 }$},x=1.792cm,y-0.0cm}{v0} ?
事实上，当我第一次尝试编译时，控制台显示：
Undefined control sequence
1.50 \Vertex
因此在搜索此评论后，我添加了代码
\usepackage{tkz-graph}.
但它仍然不起作用。我怎样才能获得晶体图？
答案1
一种可能性是安装可选的 Sagemath 包dot2tex，可以在 shell 提示符下执行以下操作：
sage -i dot2tex
此包安装在 SageMathCloud（最近更名为 CoCalc）上。另请参阅最近的讨论这里- 简而言之，这是一个 Sagemath 错误。
