SymPy Gamma currently works against a rather old version of SymPy. It needs to be updated to work with the latest version.

Hi,
so can you tell me which version sympy& python is good for SymPy Gamma

Use the previous version (from 2014) of manualintegrate.py and it will work fine

Yeas @manish182 ,
I have changed version to '0.7.5'
pip install sympy==0.7.5

Now it is working.
