I am trying to visualize the crystal graph associated to the tensor product of symmetric representations of a Kac-Moody algebra. An example of the code I am trying to run is the following.

sage: c=crystals.Tableaux('A2',shape=[2,1])                                                               
sage: G=c.digraph()                                                                                       
sage: view(G)                                                                                             
An error occurred.

...

Latex error

When called, the function view(G) gives a latex error, which I have not reported in its entirety. This seems to occur only in case the graph G has tableaux for vertices. In other instances, the function view seems to work fine. Is there a remedy to this issue? Should I install additional packages?

Welcome to Ask Sage! Thank you for your question.

This works for me after installing dot2tex.

If Sage was installed from source, one way to install dot2tex is:

sage -i dot2tex

On the Sage-macOS app, dot2tex should be installed using pip, the package installer for Python.

Two ways to do that (choose one).

From the terminal, run
```
sage --pip install dot2tex
```
Launch Sage and, from within Sage, run
```
%pip install dot2tex
```

Thanks for your answer. When inserting the command on the terminal I get the following message.

$ sage -i dot2tex
Sorry, this binary distribution does not support installing sage packages.

I am currently using a MacBook M1 with operating system Big Sur 11.1. I am not sure this helps, but just in case.

I opened an issue at Sage_macOS to add dot2tex:

For now you might try building from source or using Conda.

Edit. In the case of dot2tex, installing with pip works. I added that to the answer.
