Python code built around python3-numpy and python3-scipy (both linked
with openblas) began emitting warnings after the 0.3.19 update:
/usr/lib/python3.10/concurrent/futures/thread.py:58:
RuntimeWarning: overflow encountered in multiply
result = self.fn(*self.args, **self.kwargs)
that broke program behavior in an Azure VM environment using Intel Xeon
Platinum 8272CL CPUs; the problem was not seen on an AMD Ryzen 5 3600 or
an Intel Core i7-9750H. Downgrading openblas while leaving the rest of
the stack untouched eliminates the problem.
Unfortunately, I do not yet have a proof of concept that can be shared
publicly or more detail about the specific failure, but let's revert to
the last known good version until a specific cause can be identified.
This reverts commit 4f34f570ff.
