[Numpy-discussion] Type annotation for Numpy arrays, accelerators and numpy.typing

Hi, When Numpy 1.20 was released, I discovered numpy.typing and its documentation https://numpy.org/doc/stable/reference/typing.html I know that it is very new but I'm a bit lost. A good API to describe Array type would be useful not only for type checkers but also for Python accelerators usin

Re: [Numpy-discussion] Unreliable crash when converting using numpy.asarray via C buffer interface

I've reproduced the error you've described and got rid of it without valgrind. Those two lines are enough to avoid the segfault. But feel free to find it yourself :) Best regards, Lev On Tue, Feb 16, 2021 at 5:02 PM Friedrich Romstedt < friedrichromst...@gmail.com> wrote: > Hello again, > > Am

Re: [Numpy-discussion] ENH: Proposal to add atleast_nd function

I'm getting a generally lukewarm not negative response. Should we put it to a vote? - Joe On Fri, Feb 12, 2021, 16:06 Robert Kern wrote: > On Fri, Feb 12, 2021 at 3:42 PM Ralf Gommers > wrote: > >> >> On Fri, Feb 12, 2021 at 9:21 PM Robert Kern >> wrote: >> >>> On Fri, Feb 12, 2021 at 1:47 PM

[Numpy-discussion] What to do about structured string dtype and string regression?

Hi all, In https://github.com/numpy/numpy/issues/18407 it was reported that there is a regression for `np.array()` and friends in NumPy 1.20 for code such as: np.array(["1234"], dtype=("U1", 4)) # NumPy 1.20: array(['1', '1', '1', '1'], dtype='>> np.array(["1234"], dtype="(4)U1,i") ar
