No file config.json in dataset

[jiuweifox]

I met a problem when I try to run visualize_gqcnn_dataset.py to show the dataset like adv_synth. It failed at line439 tensor_dataset.py because there has no file "config.json", where I can find it? Thanks very much.

line439 tensor_dataset.py config_filename = os.path.join(dataset_dir, 'config.json')
