[Numpy-discussion] Moving the meetings schedule to one hour earlier
Hi all, it's that time of the year again where daylight savings time starts (the US had it already and Europe will have it now). I suggest we "realign" our meeting to this time zone (since it is scheduled as UTC), I think for our typical crowd that is the nicer time slot. (I would slightly prefer to move it, but am OK either way.) - Sebastian ___ NumPy-Discussion mailing list -- numpy-discussion@python.org To unsubscribe send an email to numpy-discussion-le...@python.org https://mail.python.org/mailman3/lists/numpy-discussion.python.org/ Member address: arch...@mail-archive.com
[Numpy-discussion] Enforce array (no-scalar) return with out=... in ufuncs
Hi all, Since it is an API decision, I have an open PR: https://github.com/numpy/numpy/pull/28576 To allow `out=...` in ufuncs (yes, three dots, the Ellipsis). NumPy normally has the bad habit of always returning scalars rather than 0-D arrays. Passing `out=...` would be one way to ensure arrays are always returned. I have picked it because: 1. to me `out=np.ndarray` might indicate no subclasses or be weird if e.g. cupy supports it (via `__array_ufunc__`). 2. `...` allures to `arr1d[0, ...]` in indexing, where including `...` ensures an array return even if it does nothing else. This is useful in a few places in NumPy, the main reason is if you have `dtype=object`. IMO, this doesn't preclude a general transition towards returning scalars less aggressively (or never), but to me it is easy and useful enough to do, even if we might have a better solution in the future. If no-one has concerns, I think we'll merge this soon, but I am always happy to hear opinions! Cheers, Sebastian PS: This PR is about ufuncs, I suppose a few odd functions might "inherit" it. We may want to allow it for other functions that have an `out=`, but it is not the case yet. ___ NumPy-Discussion mailing list -- numpy-discussion@python.org To unsubscribe send an email to numpy-discussion-le...@python.org https://mail.python.org/mailman3/lists/numpy-discussion.python.org/ Member address: arch...@mail-archive.com
