Configuration.add_subpackage fails on Python 3.4 #8147
Description
Using numpy 1.11.2 and Python 3.4, trying to run a setupy.py script which uses subpackage using numpy.distutil fails when importlib.machinery cannot be found in the npy_load_module function.
For example using the following setup.py and foo/setup.py scripts:
# setup.py
from numpy.distutils.misc_util import Configuration
from numpy.distutils.core import setup
def configuration():
config = Configuration(None, '', None)
config.add_subpackage('foo')
return config
setup(configuration=configuration)# foo/setup.py
def configuration(parent_package='', top_path=None):
from numpy.distutils.misc_util import Configuration
config = Configuration('foo', parent_package, top_path)
return configAttempting to build the package:
$ python setup.py build_ext -i
Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'machinery'
This works in Python 3.5 and 2.7 and with earlier versions of NumPy prior to the addition of npy_load_module.
This bug can likely be fixed by adding import importlib to the npy_load_module. I will submit a PR shortly.
A workaround is to import importlib.machinery somewhere in the root setup.py file.

BUG: import full module path in npy_load_module
Fix install with numpy 1.11 and Python 3.4

For some reason, python 3.6 does not initialize machinery module in init.py. However, you can import it by the following way. It is very weird.
from importlib.machinery import SourceFileLoader
config = SourceFileLoader('config', os.path.abspath('../config.py')).load_module()
