Package: python3-pynndescent
Version: 0.5.7-1

Dear Debian Python Team,
in the python3 or ipython3 interpreter, the Python statement
import pynndescent.sparse as sparse
fails and the output in ipython3 is
```

```
I'm not sure if the failure is due to this package or the package
python3-numba.
Or is this just a Python 3.11 transition outfall?
Any help appreciated.

Jörg.
