ValueError: CorrMM images and kernel must have the same stack size while running the example script

Hi,

I have been trying to follow the example script of

model = ResNet50(weights='imagenet')
img_path = '/data/dsp_emerging/ugwz/elephants.jpg'
img = image.load_img(img_path, target_size=(224, 224))
x = image.img_to_array(img)
x = np.expand_dims(x, axis=0)
x = preprocess_input(x)
preds = model.predict(x)
print('Predicted:', decode_predictions(preds))

However, I got the following error message of ValueError: CorrMM images and kernel must have the same stack size. I did not change anything in the code. Keras is of version2.0.3 and Theano is of version0.9.0

The complete traceback is
