I believe I face with this error due to Solidity compiler's default gas limit that is 3,000,000.
[Q] How could I increase my solidity compiler's gas limit due to this error, or another gas limit that populus reads from?
in estimate_gas
-> does it exceed gas limit? When I remove some function inside my contract the error gets fixed. I guess there is a gas limit for populus to deploy the contract, is it possible to extend it? If yes how?

Based on @mafrasi2 answer when I tried:
