Yep, I think the issue with R is that they're using a customised version of BLAS/LAPACK – Python has been running these things on Raspberry Pis for ages now, I suspect using a more standard implementation.
- em500 6y agoNo, the issues are different, please read the article. R also runs fine on ARM64 linux. But macOS is not linux, as mentioned in the article it has a different ABI and no free Fortran 90 compiler is available yet. The other issue is that R distinguishes between NA values and NaN values (NumPy doesn't), which are propagated differently on ARM64.
- gh02t 6y agoBased on the article I don't think those are the problem. I think the new Apple silicon is distinct enough that it needs a bit of porting effort to get a Fortran compiler running, along with the issue of quirks in handling NaN payloads and some other (seemingly rather minor) differences.
