any suggestions on this problem, i have looked the doc more than 10 tens, but still get stuck here.

it must run this command python bin/iepy_rules_runner.py PER_BIRTH_DATE, the PER_BIRTH_DATE is the relation defined in the rules.py, namely the "was born", at the same time, you must build the relation PER_BIRTH_DATE on the web( I do it first).
