predict_classes() returning only 0 or 1 for multiclass image classification I am trying to build a multi class image classifier but the only returns 0 or 1 .

Why is it not returning "Rock" , "Paper" , "Scissor" ?
and why only 0 and 1 but not 2?

CODE:

from keras.preprocessing.image import ImageDataGenerator
from keras.models import Sequential
from keras.layers import Dense, Flatten
import numpy as np


train_directory = 'D:\D_data\Rock_Paper_Scissors\Train'
training_datgagen = ImageDataGenerator(rescale = 1./255)
training_generator = training_datgagen.flow_from_directory(
    train_directory,
    target_size = (28,28),
    class_mode = 'categorical', classes = ["Rock", "Paper" , "Scissor"])

validation_directory = 'D:\D_data\Rock_Paper_Scissors\Train'
validation_datagen = ImageDataGenerator(rescale= 1./255)
validation_generator = validation_datagen.flow_from_directory(
    validation_directory,
    target_size = (28,28),
    class_mode = 'categorical',
    classes = ["Rock", "Paper" , "Scissor"]
    )


model = Sequential()
model.add(Flatten(input_shape = (28,28,3)))
model.add(Dense(128,activation = 'relu'))
model.add(Dense(64, activation = 'relu'))
model.add(Dense(16, activation = 'relu'))
model.add(Dense(3, activation = 'softmax'))

model.compile(optimizer = 'adam', loss = 'categorical_crossentropy',metrics = ['accuracy'],)
filenames = validation_generator.filenames
nb_samples = len(filenames)
desired_batch_size = 1

model.fit_generator(training_generator,epochs=20,validation_data = validation_generator)
predict = model.predict_classes(validation_generator, batch_size = None)

print(predict)


Output:

[0 1 1 ... 1 0 1]
I got the answer so I'm posting it for future reference for others:

The 3 classes defined in 

train_directory = 'D:\D_data\Rock_Paper_Scissors\Train'
training_datgagen = ImageDataGenerator(rescale = 1./255)
training_generator = training_datgagen.flow_from_directory(
    train_directory,
    target_size = (28,28),
    class_mode = 'categorical', classes = ["Rock", "Paper" , "Scissor"])


in class_mode should be Rock , Paper , "Scissors"
those were the names of the folders i create but i made a mistake and spelled "Scissors" wrong in the code.

Thanks a lot to everyone who commented!
