configparser.NoSectionError: No section: 'config'

[wentinghome]

Hi,
I'm wondering if you have this problem? I set up the following environment, and run with python experiment.py config.conf.
python (3.5.2)
numpy 1.14.0)
tensorflow (1.4.1)

The program stopped here and the err is in the following. Any thoughts or suggestions on this? Thank you.
