AttributeError: module 'tensorflow' has no attribute 'contrib'

Hello, I am using TFOD API for custom object detection.
While during last step of installation verification. After, Running following command -
!python object_detection/builders/model_builder_tf2_test.py

I faced following error. How to resolve this issue ?

I am currently using Google Colab.
Tensorflow version = 2.15.0 and I followed this documentation - https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/install.html
Pls help Thank You.
