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

Open sagemaker-python-sdk/tensorflow-eager-script-mode/tf-eager-sm-scriptmode.ipynb and inspect the first cell, especially the failing tf.enable_eager_execution() call. Reproduce the notebook CI failure, then verify that the notebook runs without the reported AttributeError and passes the relevant CI check.
