AttributeError: module 'sympy' has no attribute 'numbers'

Calling latexify(Fraction(3,8)) throws this error:

A call to Math(latexify(3/8)) avoids this line and this error.

Hi Adam,

For me the following code

from latexifier import latexify
from fractions import Fraction
latexify(Fraction(3,8))

returns '\\frac{3}{8}' as expected, so I cannot reproduce your error. I see two possible explanations:

1. You are using another Fraction module. If so could you provide a minimal working example?
2. Dependency/module version issues. This one would be more tricky to detect.

try change sympy.numbers.Integer to sympy.core.Integer
