Message-ID: Hi All, On behalf of the NumPy team, I am pleased to announce the release of NumPy 1.14.4. This is a bugfix release for bugs reported following the 1.14.3 release. The most significant fixes are: * fixes for compiler instruction reordering that resulted in NaN's not being properly propagated in `np.max` and `np.min`, * fixes for bus faults on SPARC and older ARM due to incorrect alignment checks. There are also improvements to printing of long doubles on PPC platforms. All is not yet perfect on that platform, the whitespace padding is still incorrect and is to be fixed in numpy 1.15, consequently NumPy still fails some printing-related (and other) unit tests on ppc systems. However, the printed values are now correct. Note that NumPy will error on import if it detects incorrect float32 `dot` results. This problem has been seen on the Mac when working in the Anaconda enviroment and is due to a subtle interaction between MKL and PyQt5. It is not strictly a NumPy problem, but it is best that users be aware of it. See the gh-8577 NumPy issue for more information. The Python versions supported in this release are 2.7 and 3.4 - 3.6. Wheels for all supported versions are available from PIP and source releases are available on github . The source releases were cythonized with Cython 0.28.2 and should be compatible with the upcoming Python 3.7. Contributors ============ A total of 7 people contributed to this release. People with a "+" by their names contributed a patch for the first time. * Allan Haldane * Charles Harris * Marten van Kerkwijk * Matti Picus * Pauli Virtanen * Ryan Soklaski + * Sebastian Berg Pull requests merged ==================== A total of 11 pull requests were merged for this release. * #11104: BUG: str of DOUBLE_DOUBLE format wrong on ppc64 * #11170: TST: linalg: add regression test for gh-8577 * #11174: MAINT: add sanity-checks to be run at import time * #11181: BUG: void dtype setup checked offset not actual pointer for alignment * #11194: BUG: Python2 doubles don't print correctly in interactive shell. * #11198: BUG: optimizing compilers can reorder call to npy_get_floatstatus * #11199: BUG: reduce using SSE only warns if inside SSE loop * #11203: BUG: Bytes delimiter/comments in genfromtxt should be decoded Cheers, Chuck -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: When installing the default scipy via pip on MacOS, using Python 2.7 (running in 32 bit mode) I still only get a 64 bit install of SciPy. Now, I can definitely compile my own version that has both 64 bit and 32 bit in it, but ideally someone has already made a version that also has the 32bit version. Even if it's a slightly older SciPy. Can anyone point me to such a build? Thanks. Unfortunately I need the 32 bit version, and the why is a longer story.

Yes, sorry, we dropped 32-bit a little while ago, believing no-one cared any more :) Try scipy==0.18.0 - that seems to be a real dual-arch build.

This is a major new release which supports 3D plotting. Veusz 3.0 supports 3D point plots, line plots, surface plots, function plots and volume plots, in addition to the existing great number of supported 2D plot types. The 3D capabilities use the existing Veusz system of building plots out of a number of widgets in an object-oriented fashion, providing a great deal of flexibility. To download, please visit https://veusz.github.io/download/ For more information on 3D plotting and the examples: https://veusz.github.io/3d/ https://veusz.github.io/examples3d/ For the release notes, please see: https://veusz.github.io/news/2018/06/10/veusz-3.0 Thanks Jeremy Sanders From jslavin at cfa.harvard.edu Tue Jun 12 14:39:32 2018 From: jslavin at cfa.harvard.edu (Slavin, Jonathan) Date: Tue, 12 Jun 2018 14:39:32 -0400 Subject: [SciPy-User] scipy versions and conda Message-ID: Hi all, I asked about this on the anaconda_support list but so far have gotten no response. The problem is that when I go to install various packages recently, conda tells me that scipy needs to be downgraded from 1.0.1 to 0.19.1. This occurred with pyregion and with bokeh for my python 3.6.4 environment. Does anyone know why such a downgrade might be needed (or if it's really needed)? How different is 1.0.1 from 0.19.1? From the "what's new" it looks like a fair amount has changed, though I'm not sure if I'd notice the differences in my own usage.
