This guide will shed light on the cause of this issue and provide actionable steps to resolve it.

Understanding the Error

This specific AttributeError typically arises when TensorFlow's integrated Keras version doesn't recognize the applications module. This can be due to a mismatch between Keras and TensorFlow versions or incorrect import statements.

Root Cause

The main reasons for this error include:

Version Incompatibility: Using mismatched versions of TensorFlow and Keras. It's critical to synchronize TensorFlow and Keras versions to ensure they work seamlessly together.

Incorrect Import Statement: The way you're importing the module might be incorrect. As TensorFlow evolves, the import paths also change, and older scripts might not reflect these changes.

Steps to Resolve the Issue

Step 1: Verify Your TensorFlow Version

Ensure you're using a version of TensorFlow that matches the version of Keras you're expecting to use. For instance, TensorFlow 2.x has Keras built-in, and importing standalone Keras might cause conflicts.

Run the following commands in your Python environment:

Step 2: Correct Import Statement

Since TensorFlow 2.x, Keras is integrated within TensorFlow. Make sure you use the appropriate import path:

This ensures that you are using the integrated version of Keras included in TensorFlow.

Step 3: Synchronize Updates

Updating your packages can resolve compatibility issues:
