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:

Figured out the issue, turns out I needed to run this using Python 3.11.12. Version 3.12 and 3.13 would cause this missing module error. In the tutorial it says Python 3.11+ is required but clearly it has to be just some variant of 3.11. Also it only worked on my Mac, not on any other Linux system.
