kmodes dependency SciPy installation fails on Windows 7

[nicodv]

Looks like scipy is not installing. Could you try installing that first, to see if it's due to that package and not kmodes?

Hi,
I am having the same problem. It is indeed due to a problem with installation of scipy throughpip (I had to install scipy with conda).
But even installing scipy with conda it still fails. It anyway tries to build the wheel for scipy and it fails.
Any suggestion to skip the scipy build (which should exists somewhere) ?

[nicodv]

scipy is a necessary requirement for kmodes (and for scikit-learn, for that matter, which is another requirement of kmodes), so there's no way around that.

If you manage to have Conda install a new enough version of scipy, though, kmodes will likely skip scipy installation because it will see the requirement is already fulfilled.

The required version of scipy for kmodes is written in setup.py. I've just downgraded that version to match scikit-learn, so it might be easier to install kmodes from source now.

[francescodelorenzi]

the problem for me is that even if I have scipy installed through conda it doesn't skip it when installing kmodes

[nicodv]

What scipy version do you have installed in conda?

[francescodelorenzi]

scipy 0.19.1-np113py35_0

[nicodv]

That's new enough... I don't understand why scipy would get reinstalled.

[francescodelorenzi]

downgrading scipy to 0.19.0, it doesn't try to install it. And I can get a clean installation.
It looks explicitely for 0.19.0 and 0.19.1 doesn't work
Unfortunately running the example it gives an error
RuntimeError: module compiled against API version 0xb but this version of numpy is 0xa
[cut]
ImportError: numpy.core.multiarray failed to import
I guess that it also downgraded numpy

[francescodelorenzi]

I had to update numpy as well. These are the versions for which I can run the example in your main page:
1.13.1 numpy
0.19.0 scipy
0.18.1 sklearn

Dear nicodv, I am facing exactly the same problem while installing it on windows 10. I am installin using pip install kmodes.
Installation fails when building wheels for scikit-learn and scipy. The error output is huge and below is the last line as mentioned by KobaKhit commented on Jul 14

regards,

in continuation to my above comment, below is first few lines display, when installation fails.

Failed building wheel for scipy
Running setup.py clean for scipy
Complete output from command C:\Users\Musharif.ahmed\Anaconda3\python.exe -u -c "import setuptools, tokenize;file='C:\Users\MUSHAR~1.AHM\AppData\Local\Temp\pip-build-wutfd5yp\scipy\setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" clean --all:

setup.py clean is not supported, use one of the following instead:

- `git clean -xdf` (cleans all files)
- `git clean -Xdf` (cleans all versioned files, doesn't touch
                    files that aren't checked into the git repo)

Add --force to your command to use it anyway if you must (unsupported).

Thank you very much. Kind regards
