I wanted to say thank you for posting this.
I could not for the life of me figure out how to install numpy<2.0 against Accelerate. Numpy 2.x would build correctly, but I needed <2.0 to use with a different package (spaCy). Adding the 'pip install' arguments in the developers' documentation seemed to do nothing (still openblas), but finally yours did!
I don't know if your solution is "right" or "wrong," but just know it certainly helped me! Thanks again.
