Esta es una pregunta muy específica sobre dos objetos de dibujos tikz. El primero muestra esto:
El segundo es de esta discusión:ERM pata de gallo en una forma agradable
Tengo que cambiar la configuración tikset{o tikzpicture{para que ambos funcionen.
este es un MWE:
\documentclass{article}
\usepackage{array}
\renewcommand{\arraystretch}{1.1}
\usepackage{tikz}
\usetikzlibrary{shapes.multipart}

¿Cómo puedo cambiar la primera parte para que ambas funcionen?
Editar: Parece que hay otro problema que no puedo reproducir con el MWE. Esta es una captura de pantalla del código de error. No tengo idea de dónde está Thinspce (U+2009)... El manual de entrada tampoco muestra más información útil en la página 4. (o no veo el significado...) Se agradece cualquier ayuda...
Respuesta1
La primera parte da un error, con o sin la segunda parte, porque la clave arrowno está definida.
Añade la línea
\tikzset{arrow/.style={-stealth})
al preámbulo.
