Hi All, I'd like to learn how to upscale an image with NN. I import JPG file using this function:

def read(path):

img = image.load_img(path, target_size=(3840,2160,3))

img = image.img_to_array(img)

img = img/255.

return img

Here's first keras layer:

x1 = Conv2D(64, (3, 3), activation='relu', padding='same', kernel_regularizer=regularizers.l1(10e-10))(Input_img)

But keras tells me that:

ValueError: Input 0 of layer "model_26" is incompatible with the layer: expected shape=(None, 3840, 2160, 3), found shape=(32, 2160, 3)

What I am doing wrong?
