Symbol not found error

[jsissom]

On Mac M5 Max.

Python and uv installed via brew

uv run scripts/generate.py "Your prompt" --pipeline distilled

Traceback (most recent call last):

This happens no matter what I pass to generate.py.

I tried this on an m4 mac pro and got the same error:

I figured out the cause. I have ollama installed via homebrew. It appears that the mlx required for ollama is not compatible with the one required for this script. Uninstalling ollama fixes the issue but it would be nice if this would coexist with ollama.

Thanks
