Unable to handle sympy Integral class latex

[Ritesh17]

When parsing back the obtained latex on a sympy Integral object to process_sympy(), it throws an exception. Adding code snippet and error log. Occurs on python 2.7 and 3.

The error occurs due to the extra "," being generated and if I add this line
latex_expr = latex_expr.replace("\,", "")
before passing latex_expr back to process_sympy() it seems to be working fine.

---

from sympy import *
from sympy.abc import *
from process_latex import process_sympy

expr = Integral((x+1)**2, x)
latex_expr = latex(expr)
back_to_expr = process_sympy(latex_expr)

---

Exception: I don't understand this
\int \left(x + 1\right)^{2}, dx
