While trying to use hellinger-distance-criterion from github link https://github.com/EvgeniDubov/hellinger-distance-criterion

I am not able to find some error.

In the github link, it is given the following steps:

You will need a cython "header" file (.pxd) from sklearn.

In case you've installed sklearn from source code package, you've already got it.

In case you've installed sklearn using pip install sklearn then you need to get it.

Got to https://github.com/scikit-learn/scikit-learn/tree/master/sklearn/tree Download _criterion.pxd and place it your local sklearn installation folder Linux usually at /usr/local/lib/python3.5/dist-packages/sklearn/tree Windows usually at C:\Users[user name]\AppData\Local\Continuum\Anaconda3\Lib\site-packages\sklearn\tree\

I have already installed sklearn from source code package in my Jupyter notebook. I have checked in local system and virtual environment.

Then I copied hellinger_distance_criterion.pyx in my local system and checked it in my jupyter notebook.

After that I was running following code as suggested in the github link https://github.com/EvgeniDubov/hellinger-distance-criterion for setup

from distutils.core import setup
from setuptools import setup
from Cython.Build import cythonize
import numpy

setup(
    name='hellinger-distance-criterion',
    version=0.1,
    url='github.com/EvgeniDubov/hellinger-distance-criterion',
    author='Evgeni Dubov',
    author_email='evgeni.dubov@gmail.com',
    ext_modules=cythonize("hellinger_distance_criterion.pyd"),
    include_dirs=[numpy.get_include()]
)

I got following error

ValueError: 'hellinger_distance_criterion.pyd' doesn't match any files

Please help me out to solve this error

  • The instructions from GitHub continue and show `python setup.py build_ext --inplace` should be run. Did you do that step? – rickhg12hs Jun 27 '21 at 21:43
  • Where I need to run this step? – Soudip Karmakar Jun 29 '21 at 02:33
  • After cloning the repo (or downloading/expanding the ZIP file), I think all the steps in the [Build](https://github.com/EvgeniDubov/hellinger-distance-criterion#build) instructions need to be followed. The "following code as suggested" you mentioned should be run as the instructions show, `python setup.py build_ext --inplace`. – rickhg12hs Jun 29 '21 at 12:50
