Keras: “must compile model before using it” despite compile() is used

Question

I want to create and train a CNN model in Keras for classification of banknotes. Creating models works fine with simple tutorials but not with the architecture I adopt from

Answer 1

Try This:

from keras.optimizers import Adam
opt = keras.optimizers.Adam(use your own learning rate)
model.compile(optimizer=opt, loss="categorical_crossentropy", metrics=model.compile(optimizer=opt, loss="categorical_crossentropy", metrics=['accuracy']))
