pymodpde.py symbol.Symbol not recognised with latest sympy version

[ross1234]

I am pymodpde in google corroboratory, with the latest version of sympy (v1.10.1).

In pymodpde.py, the sympy module is importing ok (line 14: from sympy import * ), however line 32 symbol.Symbol is not recognised.

I have found that rolling back to sympy version (v1.5.1), by running:
!pip install --user sympy==1.5.1

allows all references to "symbol.Symbol" in the pymodpde.py script to be recognised.

Looks like the pymodpde.py needs to be updated for the latest sympy version, or hard-code in a !pip install --user sympy==1.5.1 as an interpm fix.

thanks

Thank you for submitting this issue!
With the PyModPDE v1.1.0, I upgraded the version of all the dependencies and allowed for the installation of pymodpde using pip.
