## iow error

fixed by insttalling iow independently
```

## sckit-bio uncompatiblity

ImportError: cannot import name '_vectorize_counts_and_tree' from 'skbio.diversity._util'

I have scikit-bio = ">=0.6.3,<0.7"

No source files, tests, or entry points are named. Start by reproducing both failures on macOS Apple Silicon with Python 3.12, then inspect the project's dependency declarations and package constraints. Done means the iow requirements build succeeds and the reported scikit-bio import error no longer occurs.
