How to generate images?

[Yili-Zhang]

Hi,

I am new to neural network, so my question might be dumb.

After setting the correct environment and imported the correct library, I started to run the training.py file, but I constantly get a error:

ValueError: validation_steps=None is only valid for a generator based on the keras.utils.Sequence class. Please specify validation_steps or use the keras.utils.Sequence class.

And here is the whole output in the console:

With mu friends' help, the conclusion was the training pictures are not enough. But I looked at your code, the "training.py" would ran the "Image_Generator.py" inside, so I guess the program would automatically generate images for the users? Otherwise what should I do to generate enough amount of images as I need?

In addition, what database did you use for massive actual Korean license plates?

Thanks,
