Note that the CI before was using:

• llvmlite: 0.43.0
• numba: 0.60.0

Now it tries to use:

• llvmlite: 0.34.0
• numba: 0.51.2

[albertvillanova]

The issue is because numba-0.60.0 pins numpy<2.1 and uv tries to install latest numpy-2.1.0 with an old numba-0.51.0 version (and llvmlite-0.34.0). See discussion in their repo:

• NumPy 2.1 Support numba/numba#9708

Latest numpy-2.1.0 will be supported by the next numba-0.61.0 release in September.

Note that our CI requires numba with the "audio" extra:

• librosa > numba
