AttributeError: 'dict' object has no attribute 'has_key'

[tamio96]

I got this error when run:
python SentenceMatchTrainer.py --config_path /home/tamiomusic/BiMPM/con
figs/quora.sample.config

I only change quora.sample.config to fix with files' directory:
"train_path": "/home/tamiomusic/BiMPM/quora/train.tsv",
"dev_path": "/home/tamiomusic/BiMPM/quora/dev.tsv",
"word_vec_path": "/home/tamiomusic/BiMPM/quora/wordvec.txt",
"model_dir": "/home/tamiomusic/BiMPM/quora/logs"

Full log:
Loading the configuration from /home/tamiomusic/BiMPM/configs/snli.sample.config
Traceback (most recent call last):
