[Numpy-discussion] NumPy's BLAS library on macOS?

Would someone please answer installation questions about NumPy's BLAS on macOS? I'm not finding the answers in the release notes , the PR source, the docs , or Stack Overflow

Re: [Numpy-discussion] NumPy's BLAS library on macOS?

'accelerate' is in the default search order after 'openblas'. On macOS < 11.3, importing numpy that's linked to Accelerate will detect an Accelerate bug and raise a RuntimeError. On Wed, Jul 7, 2021 at 1:32 PM Ralf Gommers wrote: > > > On Wed, Jul 7, 2021 at 9

[Numpy-discussion] Re: Consider linking to Accelerate in Apple Silicon ARM64 wheels

This sounds terrific. Is there a technique to get such a performance improvement with Accelerate? We tried: pip install numpy==1.24.3 --no-binary numpy with and without a ~/.numpy-site.cfg file that sets [accelerate] libraries = Accelerate, vecLib on Intel and M2 Macs on macOS 13.3. While np
