python 2.7 - How to properly install a NumPy ufunc? -

i trying install example ufunc scipy docs when run python setup.py build or python setup.py install few warnings deprecated numpy api.

when run python setup.py install output:

running python setup.py build produces:

if try import module get:

traceback (most recent call last):   file "<pyshell#0>", line 1, in <module>     import npufunc importerror: no module named npufunc 

does know how make work?

according documentation "the __init__.py files required make python treat directories containing packages". setup.py in numpy documentation not create file, python not import ignores directory.

solution: add empty __init__.py file in /usr/local/lib/python2.7/dist-packages/npufunc_directory directory, example sudo touch __init__.py try:

>>> npufunc_directory import npufunc >>> npufunc.logit(.5) 0.0 

alternatively, add import npufunc __init__.py , can do:

>>> import npufunc_directory >>> npufunc_directory.npufunc.logit(0.5) 0.0
