WebSep 11, 2024 · images = np.vstack (images) This same prediction is being appended into images_data Assuming your prediction is not failing, it means every prediction is the prediction on all the images stacked in the images_data. So, for every iteration for i in range (len (images_data)): This images_data [i] [0] is returning you the 1st prediction only.
