WebNaturally what you want if to 1 epoch your generator pass through all of your training data one time. To achieve this you should provide steps per epoch equal to number of batches like this: steps_per_epoch = int( np.ceil(x_train.shape[0] / batch_size) ) as from above equation the largest the batch_size, the lower the steps_per_epoch.
