   Which openblas version are you using?
   Which cython version are you using?
   Did you build using meson or distutils?

   The cholesky error is most likely due to blas.

   The only changes in numpy/random were changing the cython binding directive (#24606) and a slight annotation improvement. The wheels we built did not error.

   I put the details in the issue text (under Runtime information:); it's openblas 0.3.24 and Cython 3.0.2.

   Did you build using meson or distutils?

   Meson on all platforms.

   The cholesky error is most likely due to blas.

   Yeah, 0.3.24 came out not too long ago, I can retest with 0.3.23.

   I think the previous 1.26.0b1 may have been using lapack-lite for nmpy.linalg by mistake instead of OpenBLAS

   Can confirm that aarch passes with openblas 0.3.23.

   @martin-frbg, this looks like a regression in 0.3.24. Do you want me to open an issue for OpenBLAS or perhaps you have a possible culprit in mind already based on the error in the cholesky test?

   Which flavor of aarch64 is this ? The only very recent change that made it into 0.3.24 was the ROTG rewrite to use the new "safe" scaling algorithm from the Reference BLAS, most everything else was specific to NeoverseV1.

   Since this is running in emulation through QEMU, I'm guessing it's the "most vanilla possible"? Numpy has some CPU feature detection on aarch as well, but doesn't find any CPU features (printed before the test suite run).

   NumPy version 1.26.0rc1
   NumPy relaxed strides checking option: True
   NumPy CPU features:  nothing enabled

    Since this is running in emulation through QEMU, I'm guessing it's the "most vanilla possible"? Numpy has some CPU feature detection on aarch as well, but doesn't find any CPU features (printed before the test suite run).

    According to the build log:

    Test features "NEON_FP16" : Unsupported due to Implied feature "NEON_VFPV4" is not supported

    The compile-time test for NEON_VFPV4 located at https://github.com/numpy/numpy/blob/main/numpy/distutils/checks/cpu_neon_vfpv4.c seems to have failed. Is there a way we can access the meson build log to pinpoint the problem? Perhaps by using something like cat build/meson-logs/meson-log.txt?

    I think these are always going to fail because we're cross-compiling on aarch. It sounds conceptually similar to #24414, which where we have to set an explicit value for cross-compilation to pass for osx-arm.

    gh-24698 should close the important part of this issue, which is the Linux aarch64 accuracy issues.

    The PyPy on Windows + memory allocator / Cython / f2py are all the same issue it looks like: sys.stdout not having an "encoding" attribute:

    AttributeError: 'NoneType' object has no attribute 'encoding
    

    I'm not sure why sys.stdout is weird under PyPy on Windows there, but it's a test issue only and shouldn't impact anything of interest. We have a PyPy on Windows CI job, but it's running the default (fast) test suite rather than the full test suite. @h-vetinari it should be fine to mark these as broken to get the conda-forge CI to pass I think. We may want to open a follow-up issue here, but it's too low-prio to look at now imho.

    and it should be fixed by the following patch:
    mesonbuild/meson@82d41db

    Thanks a lot @seiko2plus!

    Is this going to be upstreamed into meson? Because if I mark the openblas 0.3.24 builds unbroken again on aarch, this would also rebreak the CI on the scipy-feedstock (which, being built by meson, is probably affected by the same issue).

    In other words, we'd at least need to patch this into the meson-feedstock, but I'd prefer to do just a backport of an upstream PR, rather than original patches.

    Agreed, issues with pypy on windows would not have kept us from releasing (on the conda-forge side at least)

    This bug is in code that is not present in Meson and not relevant for SciPy because it doesn't use NEON SIMD.

    Interesting... That means we're still lacking an understanding of what's causing scipy/scipy#19210, and I cannot mark openblas 0.3.24 unbroken again.

    In any case, nothing that should be blocking 1.26

    The issues seem to stem from the compiler optimization being disabled by setting the optimize level to 0. Upon inspecting the provided meson log, I noticed that -O0 is specified after both -O3 and -O2, which is unusual.

    Check the following command line:

    Command line: `$BUILD_PREFIX/bin/aarch64-conda-linux-gnu-cc -L$PREFIX/lib $SRC_DIR/builddir/meson-private/tmp3f10l7c1/testfile.c -o $SRC_DIR/builddir/meson-private/tmp3f10l7c1/output.exe -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt \
    -O3 \ # optimization level 3

    -pipe -isystem $PREFIX/include -fdebug-prefix-map=$SRC_DIR=/usr/local/src/conda/numpy-1.26.0rc1 -fdebug-prefix-map=$PREFIX=/usr/local/src/conda-prefix -DNDEBUG -D_FORTIFY_SOURCE=2 \
    -O2 \ # optimization level 2 overrides the O3

    -isystem $PREFIX/include -D_FILE_OFFSET_BITS=64 \
    -O0 \ # And here the issue ? the compiler optimization is turned off?

    -std=c99 \ 
    -Wl,-O2 \ # passing O2 to linker? void it.
    -Wl,--sort-common -Wl,--as-needed -Wl,-z,relro -Wl,-z,now -Wl,--allow-shlib-undefined -Wl,-rpath,$PREFIX/lib -Wl,-rpath-link,$PREFIX/lib` -> 1

    It seems that the Meson build reverses the order of the CFLAGS for somehow and this may explains why we don't observe this issue in the distutils build.

    Conda manages to make things a little messy with a ton of build flags, but I think we can unravel this. We have the following components of the puzzle for a C target:

    1. The default_options in the top-level meson.build file: -std=c99 (other relevant flags there get overridden by meson-python, see (2):)
    2. The flags that meson-python adds when building a wheel: -Dbuildtype=release, -Db_ndebug=if_release`
    3. c_args set for a particular build target in the relevant meson.build file
    4. CFLAGS and LDFLAGS set in the environment (comes from compiler activation):

    $ echo $CFLAGS
    -ftree-vectorize -fPIC -fPIE -fstack-protector-strong -O2 -pipe -isystem /Users/rgommers/mambaforge/envs/numpy-dev/include
    $ echo $LDFLAGS
    -Wl,-pie -Wl,-headerpad_max_install_names -Wl,-dead_strip_dylibs -Wl,-rpath,/Users/rgommers/mambaforge/envs/numpy-dev/lib -L/Users/rgommers/mambaforge/envs/numpy-dev/lib
    

    It's unclear to me where -O0 comes from, or -Wl,-O2.

    To get the compile and link args for a target, you can use meson introspect build --targets -i > tmp.json. Example output in a numpy-dev conda env:

    Those do both contain -O0, so I think it's coming from Meson's compiler feature check support. Which I guess makes sense for cc.has_header and the like. But not so much for SIMD checks perhaps.

    @seiko2plus are those actual problems for feature detection? It's working fine in all CI and locally, with -O0 included.

    Thanks for clarifying. I was under the impression -O0 was applied to all sources, as I couldn't access the ninja debug log via CI.

    are those actual problems for feature detection? It's working fine in all CI and locally, with -O0 included.

    The presence of -O0 isn't a problem for feature detection. In fact, it's beneficial to include -O0 to prevent the optimization of any instructions pertinent to the test, allowing for direct assessment against the assembler.
