[Numpy-discussion] NumPy 1.11.0b3 released.

Hi All, I'm pleased to announce the release of NumPy 1.11.0b3. This beta contains additional bug fixes as well as limiting the number of FutureWarnings raised by assignment to masked array slices. One issue that remains to be decided is whether or not to postpone raising an error for floats used a

On Nix we also had trouble with OpenBLAS 0.2.15. Version 0.2.14 did not cause any segmentation faults so we reverted to that version. https://github.com/scipy/scipy/issues/5620 (hopefully this time the e-mail gets through) On Tue, Feb 9, 2016 at 10:21 AM, Daπid wrote: > On 8 February 2016 at 20

Re: [Numpy-discussion] resizeable arrays using shared memory?

Hi, If the base address and size of the anonymous memory map are 'shared', then one can protect them with a lock, grow the memmap with remap (or unmap and map, or other tricks), and release the lock. During the 'resize' call, any reference to the array from Python in other processes could just spi
