CNN model for prediction

[19IT089-Shruti-S]

Hi, Can I to use your CNN model to detect numbers on a page by giving an image as input? the images are similar to the one below.

I tried using model.predict() and passed image as input. but am getting IndexError: tuple index out of range.
Any idea on how to resolve this. I am new to python and image processing and am greateful for any kind of help
