[Numpy-discussion] Behavior of np.random.uniform

Hi all, There is a PR (#7026 ) that documents the current behavior of np.random.uniform when the low and high parameters it takes do not conform to the expected low < high. Basically: - if low < high, random numbers are drawn from [low, high), - if

Re: [Numpy-discussion] Behavior of np.random.uniform

Are there other functions where this behavior may or may not be happening? If it isn't consistent across all np.random functions, it probably should be, one way or the other. Ben Root On Tue, Jan 19, 2016 at 5:10 AM, Jaime Fernández del Río < jaime.f...@gmail.com> wrote: > Hi all, > > There is a

Re: [Numpy-discussion] Behavior of np.random.uniform

Of the methods defined in *numpy/mtrand.pyx* (excluding helper functions and *random_integers*, as they are all related to *randint*), *randint* is the only other function with *low* and *high* parameters. However, it enforces *high* > *low*. Greg On Tue, Jan 19, 2016 at 1:36 PM, Benjamin Root

Re: [Numpy-discussion] Behavior of np.random.uniform

For what it is worth, the current behaviour seems the most logical to me, i.e., that the first limit is always the one that is included in the interval, and the second is not. -- Marten ​ ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org https:

Re: [Numpy-discussion] Behavior of np.random.uniform

In rand range, it raises an exception if low >= high. I should also add that AFAIK enforcing low >= high with floats is a lot trickier than it is for integers. I have been knee-deep in corner cases for some time with *randint* where numbers that are visually different are cast as the same number

Re: [Numpy-discussion] Behavior of np.random.uniform

What does the standard lib do for rand range? I see that randint Is closed on both ends, so order doesn't matter, though if it raises for b wrote: Of the methods defined in *numpy/mtrand.pyx* (excluding helper functions and *random_integers*, as they are all related to *randint*), *randint* is the

> Last month, numpy had ~740,000 downloads from PyPI, Hm, given that Windows and Linux wheels have not been available, then that's mostly source installs anyway. Or failed installs -- no shortage of folks trying to pip install numpy on Windows and then having questions about why it doesn't work.

In principle, if we are describing an *interval*, that is the right thing to do: https://en.wikipedia.org/wiki/Interval_(mathematics)#Including_or_excluding_endpoints Alan Isaac On 1/19/2016 9:21 AM, G Young wrote: Of the methods defined in *numpy/mtrand.pyx* (excluding helper functions and *

just to not prevent it from the black hole - what about integrating fromiter into array? (see the post by Benjamin Root) for me personally, taking the first element for deducing the dtype would be a perfect default way to read generators. If one wants a specific other dtype, one could specify it l

Hi All, I've branched 1.11.x. There is still work to be done, but the branch draws the line for PRs to be included in 1.11. Experience teaches that fixups will needed, but new work/enhancements will be in 1.12.0-dev0. Please run tests on this branch if you have the time. Travis CI has begun fail
