I think that's pretty much the same thing as removing the test sources from default distribution completely, which I'm probably -1 on, but happy to lose that debate if the majority prefer it... I just don't see the bandwidth benefit as justified for non-data assets, but I realize others disagree.

I think the common ground might be using python "optional dependencies" [1] such that only interested parties install it and the rest can skip the extra network payload. You can then install "pip/conda install scipy[full]" or whatever the syntax might be.

FWIW, I'm in favor of moving large data assets out, but my preference would be to always have the sources of tests in the main repo. The debates about this
aren't super interesting/fun, but anyway that's where I land on it, even if the project goes in another direction.

Best wishes,

Hi all,

This is an FYI that in conda-forge, thanks to the hard work of @h-vetinari [1], the `scipy` package now no longer contains tests. Instead, those are split off into a new `scipy-tests` package which, when you install that, puts all the test files back inside the `scipy` package tree.

The gain of that exercise was a ~30% size reduction, which seems worth it. We already had plans to do something similar in SciPy itself, by putting the heavy data files from the test suite under `scipy.datasets`. The gain of that will be less, probably 15-20% of the total size of wheels (excluding vendored openblas et al.). The conda-forge packages are a nice test case - if we receive no complaints from that, it should be pretty safe to move forward with that plan.

Cheers,
Ralf
