Re: [Numpy-discussion] How do I ensure numpy headers are present in setup.py?
Hmm, unfortunate. So the best approach then is probably just to tell people to install numpy first, then my package?

Not only does this make users more aware of their environment (ie, the distinction between your package and the major numerical package in Python), but its so much cleaner. With the combined approach, any NumPy installation problems would be (frequently) associated with your package. On the other hand, if there are any NumPy installation problems in the separated approach, at least your package is blameless. ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

Is it possible to kill an installation subprocess with CRTL-C ? Hmm, that's a good question. Just thinking about it, I don't think it would. From the docs: Popen.kill() Kills the child. On Posix OSs the function sends SIGKILL to the child. On Windows kill() is an alias for terminate(). But, I listed the check_call() function, which waits for the subprocess to end. You never actually get the handle to the subprocess object to issue the kill() command. So, I'm not sure how you could make it work.

[Numpy-discussion] How do I ensure numpy headers are present in setup.py?
I am writing a setup.py file for a package that will use cython with
numpy integration. This of course requires the numpy header files,
which I am including by using numpy.get_includes in the setup.py file
below. The problem is for users that have not installed numpy before
installing this package.If they have setuptools installed, the
behavior I would want would be for numpy to be downloaded and then the
setup script should be able to get at the headers even if it doesn't
install numpy until after this package is installed. But that doesn't
work - I have to import numpy in the setup script, which fails if it
is not yet installed. So How can I get the behavior I want?
setup.py
from distribute_setup import use_setuptools
use_setuptools()
from setuptools import setup
from setuptools.extension import Extension
from Cython.Distutils import build_ext
from numpy import get_include as numpy_includes
ext_modules = [Extension(myext,
[core.pyx,somecfile.c],include_dirs=[numpy_includes()])]
setup(
name = 'ext name',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules,
setup_requires=['numpy'],
install_requires=['numpy'],
)
