Missing module 'coremltools.libmilstoragepython'

Hello!

I'm following the Foundation Models adapter training guide (https://developer.apple.com/apple-intelligence/foundation-models-adapter/) on my NVIDIA DGX Spark box. I'm able to train on my own data but the example notebook fails when I try to export the artifact as an fmadapter. I get the following error for the code block I'm trying to run. I haven't touched any of the code in the export folder. I tried exporting it on my Mac too and got the same error as well (given below). Would appreciate some more clarity around this. Thank you.

Code Block:

from export.export_fmadapter import Metadata, export_fmadapter

metadata = Metadata(
    author="3P developer",
    description="An adapter that writes play scripts.",
)

export_fmadapter(
    output_dir="./",
    adapter_name="myPlaywritingAdapter",
    metadata=metadata,
    checkpoint="adapter-final.pt",
    draft_checkpoint="draft-model-final.pt",
)

Error:
