model.predict() returns classes and not probabilities

Question

Hello!

I am using Keras for first time. I trained and saved a model. (as a json file and its weights too) The model it is intended to classify an image among 3 classes. My compile method :

model.compile(loss='categorical_crossentropy',
              optimizer='adam',
              metrics=['accuracy'])

After that, I load the model and its weights and i try to make a prediction for a random image

# Predicting images
img =image.load_img('/path/to/image/index.jpeg', target_size=(224, 224))
x = image.img_to_array(img)
#normilize the array output
x *= (255.0/x.max())
image = np.expand_dims(x, axis = 0)
image = preprocess(image)
preds = loaded_model.predict(image,)
pred_classes = np.argmax(preds)
print(preds)
print(pred_classes)

How to i get a list with the probabilities? For example [75% 15% 10%] Currently i get as an output

[[5.571262e-21 0.000000e+00 1.000000e+00]]

This is the model summary print(loaded_model.summary()) Model successfully loaded from disk!

You already have the probabilities :)

Look at your list:

[[5.571262e-21 0.000000e+00 1.000000e+00]]

and the probabilities are:

0, 0, 1

Btw, it looks like the overfitting . Check this page: https://www.kdnuggets.com/2015/04/preventing-overfitting-neural-networks.html
