Can you generate the changes in .py file, it would be easier to make the code review.

Sure @sachinprasadhs - I'll do it and commit again.

Migration to Keras 3 should be the modified changes to the existing file here https://github.com/keras-team/keras-io/blob/master/examples/vision/handwriting_recognition.py and here https://github.com/keras-team/keras-io/blob/master/examples/vision/ipynb/handwriting_recognition.ipynb, no need to create a new file.

Okay. I'll replace my file with existing one.
