SciPy v1.11.0

[h-vetinari]

Let's try building 1.11.0!

Closes #241

[conda-forge-webservices]

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Windows tests are irrelevant, that's just because the tests changed parametrization (& thus serialization). I'll let the CI run to completion then push a fix for that (also numpy upper bound).

So I don't know how this happened between rc1 & rc2, but we have two new crashes for PyPy + win

__________________ stats/tests/test_sensitivity_analysis.py ___________________
[gw1] win32 -- Python 3.9.16 %PREFIX%\python.exe
worker 'gw1' crashed while running 'stats/tests/test_sensitivity_analysis.py::TestSobolIndices::test_raises'
__________________________ stats/tests/test_stats.py __________________________
[gw0] win32 -- Python 3.9.16 %PREFIX%\python.exe
worker 'gw0' crashed while running 'stats/tests/test_stats.py::TestMode::test_negative_axes_gh_15375[axis0]'

In the same test suite run there was another test failing due to lack of memory:

E   numpy.core._exceptions._ArrayMemoryError: Unable to allocate 12.0 MiB for an array with shape (3, 1, 524288) and data type float64

so memory pressure might have something to do with it. I'll restart the builds once CI finishes to double-check.

That's unfortunate, but not enough to hold up the release IMO. CC @mattip

I tried running the pypy windows build on a VM with 10GB memory and it passed.

I guess we can just chalk that one up to memory pressure then and skip it here...

Really no idea what change between rc2 & GA could cause PyPy to die on aarch/pcc...

And now the ppc one passed. Good enough for now, can still debug more later.

We are having a weird issue, when after updating to 1.11.0 in conda-forge, cvxpy fails to start:

@noamgat that seems like a SciPy bug, can you please open an issue at https://github.com/scipy/scipy/issues?

[h-vetinari]

I started taking a look and my findings became long enough that I ended up filing an issue directly: scipy/scipy#18749

[h-vetinari]

@noamgat, while we sort this out, the simplest (and essentially only) solution is to add a constraint scipy <1.11 to your environment.

PS. Thanks for the quick feedback!

[noamgat]

Thanks for opening the issue! I wasn't sure if it was related to the package or the feedstock
