Cannot import bnurbs from cpp_utils.

[MitchD42]

When trying to run the Hello World sample I hit an error where blender can't import bnurbs from the cpp_utils folder. I had a theory that it was because the bnurbs file was a .pyx file so I converted the file from Cython to Python and tried to run it again. Now I think I've really broke it. The new error is that numpy has no attribute 'bool'.

I am heavily relying on ChatGPT for any coding so bear in mind I am no programmer.

This happens every time I try to run: blender -noaudio --background --python generate.py -- --seed 0 --task coarse -g desert simple --output_folder outputs/helloworld/coarse

  `np.bool` was a deprecated alias for the builtin `bool`. To avoid this error in existing code, use `bool` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.bool_` here.
  The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
  https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations. Did you mean: 'bool_'?

Blender quit

** (If this is your first time running Infinigen) What are the full output logs of `install.sh` ?**

I'm not sure how to find these as I've opened and closed my WSL a couple times.

**Platform**
- OS & OS Version: Windows 11 - Version 10.0.22621 Build 22621
- GPU (?) : NVIDIA GeForce RTX 2080 Ti
- GPU Driver Version (?) : 31.0.15.2824
- RAM (GB): 12 GB

**Additional context**
I'm running:
- Windows Subsystem for Linux
- Python3

This was the original error before I tried to edit the bnurbs.pyx file:

Not yet, I'm swamped this weekend but I'll update if I find a solution.

[louis-fashion-ai]

You can cd "/opt/infinigen/worldgen/assets/creatures/geometry/cpp_utils", and "python setup_linux.py build_ext --inplace"

[araistrick]

Hello, I recommend @louis-fashion-ai 's solution, cd-ing into that folder and rerunning the relevant setup.py should re-attempt installation, and/or show some error message as to why it is not able to cythonize the bnurbs module. If this doesn't resolve the issue, then it may get fixed in 1.1 in a few weeks, as I have reworked installation quite a bit.
