I am trying to do Kmeans with sklearn and I am getting weird error that says:

Traceback (most recent call last):
  File "kmean_test.py", line 2, in <module>
    from sklearn.cluster import KMeans
  File "C:\Python\lib\site-packages\sklearn\cluster\__init__.py", line 6, in <module>
    from .spectral import spectral_clustering, SpectralClustering
ModuleNotFoundError: No module named 'sklearn.cluster.spectral'

Working on Windows, I tried importing in Jupyter and just running a simple script from command.

I have tested my install of Scikit-Learn with the following imports and they work fine. 

from sklearn import datasets

from sklearn import naive_bayes

First bit of code that i get the traceback error looks like:

import cv2, numpy as np
from sklearn.cluster import KMeans

def visualize_colors(cluster, centroids):
...

I got this import code

from sklearn.cluster import KMeans

from two tutorial sources but perhaps it is the problem? I have made attempts to import otherways but been unsuccessful

Just in case it was the sklearn install and because of reading through other stackoverflow suggestions I have:

I have tried uninstall and reinstall of numpy (with and without mkl), pandas, scikit-learn, and scipy both from regular command and admin command.

I have tried update as well.

I have downloaded the wheels and run install as administrator.

I am new. Please be kind. I am new to Windows development as well, Ugh! So if it has something to do with some complicated Windows system setup and software install etc etc I may not follow. I have spent 2 days trying to solve this one on my own and finally decided to reach out.

Thanks for any help!

UPDATE:

As per suggested below I have confirmed I do have the most recent version of sklearn 0.21.3

import sklearn
print(sklearn.__version__)
0.21.3

For the record here are my versions of the others:

python --version
Python 3.7.3

import numpy
numpy.version.version
'1.17.2'

import scipy
scipy.version.version
'1.3.1'

import pandas as pd
pd.__version__
'0.24.2'

Finally I would like to mention that I have been able to successfully apply Kmeans to my project without sklearn, however, I am trying to access the % and RGB values of the means. I have found two people showing how to do it and BOTH use sklearn. See here end comment by nathancy on why I am trying to install sklearn to do this specific thing: How to find the average colour of an image in Python with OpenCV?

You have installed an older version of sklearn.

from sklearn.cluster import KMeans with work only if you have the latest sklearn version which is 0.21.3

To check the version use:

import sklearn

print(sklearn.__version__)

Finally install sklearn latest version:

pip install -U scikit-learn

  • I have confirmed i do have the latest version of sklearn. 0.21.3 – Sarah Plane Oct 04 '19 at 15:52
  • try this: `pip uninstall scikit-learn ; sudo pip install scikit-learn`. Youn sklearn installation is broken – seralouk Oct 04 '19 at 16:40
  • There is no sudo command for Windows. I already did the equivalent which is running as Admin as mentioned above. Also other modules of sklearn are working just fine. – Sarah Plane Oct 04 '19 at 17:14
