Installing datasets[audio] leads to numba package also being installed. Because of this, tbb needs to be installed as well. This is because with numbda installed, but tbb not installed, the following error is raised inside INC:

ValueError: No threading layer could be loaded.
HINT:
Intel TBB is required, try:
$ conda/pip install tbb

After both numba and tbb are installed, INC starts to pack bits relying on these packages. For example: https://github.com/intel/neural-compressor/blob/master/neural_compressor/torch/algorithms/weight_only/modules.py#L456-L457

@IlyasMoutawwakil As we've agreed before, could you please invite somebody from INC side for a review?
