TensorFlow 'Transformer' Layer Import Error: Troubleshooting Guide

The error message 'cannot import name 'Transformer' from 'tensorflow.keras.layers'' suggests a problem with importing the Transformer layer from tensorflow.keras.layers. This could be caused by several issues:

1. Unsupported TensorFlow/Keras Version: The Transformer layer might not be available in your current version. Ensure you have the latest version of TensorFlow and Keras installed. Refer to the official documentation to check if the Transformer layer is supported in your version.

2. Version Conflict: Conflicting versions of TensorFlow and Keras can cause import errors. Uninstall and reinstall both packages to guarantee compatibility.

3. Installation Issues: Problems with your TensorFlow or Keras installation might be the culprit. Reinstall the packages or create a new virtual environment to eliminate this possibility.

If these solutions fail, consider using a different deep learning framework or layer that offers similar functionality.
