Research direction
Locate the get segments function in the YouTube 8M repository, likely in a data processing script. Review the current implementation to understand how it works. Identify opportunities to use TensorFlow operations (e.g., tf.map fn, tf.data) for performance gains. Implement the migration, ensuring correctness by comparing outputs. Consider adding tests to validate the changes.
