As per README.md instructions I got the error upon running the suggested unit test:

Hi @jabowery,

It sounds like you are having problems with the functions producing latex versions of the expressions generated by physo.

I am unable to reproduce this error on my ubuntu system.

  1. Can you check that your version is:

    matplotlib >= 3.5.1

  2. Can you test that this snippet works correctly in the environment you are using to run physo ?

    
import sympy
import matplotlib.pyplot as plt

expr_str = "(sin(((ft)+phi))exp((alpha*-(t))))+1-1"

Getting a sympy expression

expr_sympy = sympy.parsing.sympy_parser.parse_expr(expr_str, evaluate=False)

If you want the simplified version

expr_sympy = sympy.simplify(expr_sympy, rational=True)

Getting a latex expression

expr_latex = sympy.latex (expr_sympy)

Getting a figure containing expression

fig, ax = plt.subplots(1, 1, figsize=(10, 2)) ax.axis('off') text_pos = (0.0, 0.5) ax.text(text_pos[0], text_pos[1], f'${expr_latex}$', size = 16)

plt.show()



3. It looks like you are not the only one having this problem with matplotlib + latex, maybe this is useful ?

jabowery commented 1 year ago

I corrected my situation by performing:

$ sudo apt install cm-super It's rather strange that this font isn't installable under at least conda if not pip if there are going to be such dependencies.

WassimTenachi commented 1 year ago

Yes it is strange. If a lot of users end up encountering this issue, I might change the plot font to avoid such issues.

ale-munozarancibia commented 1 year ago

In Fedora 35, I kept having the "not found" error for type1ec.sty and type1cm.sty in matplotlib although both were installed. I was able to solve it installing texlive-psutils with dnf.
