antlr3 python ANTLR version mismatch

[XiaoshanLin9701]

I installed antlr 3.1.3 python-runtime library for python 2.7 by running the setup.py file. But when I run my code, it throws an error: RuntimeError: ANTLR version mismatch: The recognizer has been generated by V3.0.1, but this runtime is V3.1.3. Please use the V3.0.1 runtime.

The recognizer comes with 3.1.3 library. I don't know why it is wrong. I try to change the recognizer version to 3.1.3 and it's still not working.

Could you help me with that issue?
