Including .f2py_f2cmap in numpy.distutils?
by Eric Hermes Sept. 28, 2015

Sept. 28, 2015

Hello, I am attempting to set up a numpy.distutils setup.py for a small python program that uses a Fortran module. Currently, the setup is able to compile and install the program seemingly successfully, but the f2py script erroneously maps the data types I am using to float, rather than double. I have the proper mapping set up in a .f2py_f2cmap in the source directory, but it does not seem to be copied to the build directory at compile time, and I cannot figure out how to make it get copied. … [View More]

Fixing the dtype of np.full's return value
by Antony Lee Sept. 27, 2015

Sept. 27, 2015

Hi all, The docstring of np.full indicates that the result of the dtype is `np.array(fill_value).dtype`, as long as the keyword argument `dtype` itself is not set. This is actually not the case: the current implementation always returns a float array when `dtype` is not set, see e.g. In [1]: np.full(1, 1) Out[1]: array([ 1.]) In [2]: np.full(1, None) Out[2]: array([ nan]) In [3]: np.full(1, None).dtype Out[3]: dtype('float64') In [4]: np.array(None) Out[4]: array(None, dtype=object) The … [View More]

ANN: Numpy 1.10.0rc1 released.
by Charles R Harris Sept. 24, 2015

Sept. 24, 2015

Hi all, I'm pleased to announce the availability of Numpy 1.10.0rc1. Sources and 32 bit binary packages for Windows may be found at Sourceforge <https://sourceforge.net/projects/numpy/files/NumPy/1.10.0rc1/?upload_just_c…>. Please test this out, as I would like to move to the final release as rapidly as possible and the lack of error reports from the beta has left me nervous. It's been quiet, too quiet. In the movies, we would all die in the next five minutes. Cheers Chuck

Re: [Numpy-discussion] "Become an Open Source Contributor" workshop
by Scott Collis Sept. 24, 2015

Sept. 24, 2015

Hey Jamie, List, Having just come back from a conference where our toolkit, Py-ART [1] has picked up a nice following of people keen to contribute I was wondering if you will be opening this up via a google hangout or similar? I would love to advertise this to our users. We all want more contributors and a big roadblock is understanding the fork and pull request system of GitHub We did run a course that had some GitGub etc here: https://github.com/scollis/SusSoPrac You are welcome to use … [View More]anything liberally!
