ModuleNotFoundError: No module named 'tflite_support.task'

tflite_support's task library is missing. I've install the tflite_support with pip install tflite-support. I've tried using help() function to get the pakage content with help(tflite_support) and got the output 'PACKAGE CONTENTS _pywrap_codegen _pywrap_flatbuffers codegen flatbuffers (package) metadata metadata_schema_py_generated schema_py_generated'. There is no task library inside like how the tflite website shows https://www.tensorflow.org/lite/inference_with_metadata/task_library/object_detector#run_inference_in_python. I get the same result doing it in my window pc. Am I doing anything wrong or the task library is just missing?
