Thanks for your inspiring work!
we follow your provided step: first create the hdf5 files with make_dataset.py, and then use create_json.py to generate the json file. However, when we python train.py train.json val.json, there is an issue--------
train_data/22/._069.jpg occurs and index = int(float(img_name.split('.')[0]))
ValueError: could not convert string to float: ''
