@willbattel installing packaging module resolve this. We will add this as a dependency

@srikris Can you add packaging module dependency to setup.py?
packaging module is used in https://github.com/apple/coremltools/blob/94737631ebef98fddd9351057bfc4f2f8f626349/coremltools/_deps/__init__.py#L15

what should I do before this gets fixed?

Is there a manual way too add the dependancy of packaging as an work around. I am running 4.0b3 and would like to be able to import coremltools.

You can install packaging yourself. For example, if using pip, simply pip install packaging.
