Data Conversion has issues

[zzs95]

Data conversion description and code do not match.
Should uncomment this line for the first time running in train.py

data_generator.build_dataset(val_index, test_index, opt.test_mode) # uncomment for online data generation

Thanks for pointing it out. This line of code should indeed be uncommented for the first time of training. Once the dataset has been generated, we can comment this line to skip the data generation process. I've uncommented this line in the train.py.
