Oh, and do you see if this is producing a `cysignals_crash_logs/` directory anywhere?
To be clear this has nothing specifically to do with plotting. It is more likely a bug in OpenBLAS or some other linear algebra code used by numpy+matplotlib. It just...
@holgerurbanek Thanks for trying. I wasn't sure if a cysignals crash log would even be produced for this, but it was worth a look, so thanks for checking. Does it...
Possibly related, but I'm not sure: https://trac.sagemath.org/ticket/29537#comment:25
Perhaps also related: https://trac.sagemath.org/ticket/31007 and the corresponding OpenBLAS fix: https://github.com/xianyi/OpenBLAS/pull/2960 Though I'm not sure why since your CPU does have AVX2 support. (I previously wrote something along the lines of...
For what it's worth there have been several other reports of an issue like this, and it's also showing up on some of our CI builds. I suspect the issue...
@holgerurbanek By any chance does running ```python >>> import numpy >>> np.linalg.inv(np.random.rand(24, 24)) ``` crash?
@holgerurbanek Thanks for continuing to investigate. We're pretty sure the problem has to do with Numpy's new SIMD intrinsics, and that some of them are not disabled at compile-time making...
No, almost certainly nothing directly to do with matplotlib.
@woodringct Thank you for the detailed reports, but please save yourself from worrying about or overthinking this too much, as it's not actually a deep mystery what's going on here....
