Sklearn Datasets

Question

I am trying the code from sklearn.datasets import load_iris. For this I have installed sklearn module in my python 2.7.6 but it is showing me long error

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    from sklearn.datasets import load_iris
  File "C:\Python27\lib\site-packages\sklearn\datasets\__init__.py", line 23, in <module>
    from .twenty_newsgroups import fetch_20newsgroups

    from ..preprocessing import normalize

    from ._function_transformer import FunctionTransformer
  File "C:\Python27\lib\site-packages\sklearn\preprocessing\_function_transformer.py", line 2, in <module>
    from ..utils import check_array
ImportError: cannot import name check_array

I want to know if installing sklearn module is enough or am I missing something? Please Help. Also I am working on Win 8.1

If you're on Windows you could use the packages from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn (maybe also re-install numpy) — user2314737, Dec 26 '16 at 21:01
What version of sklearn are you using? Check this: http://stackoverflow.com/questions/29596237/import-check-arrays-from-sklearn — Lukasz Tracewski, Dec 27 '16 at 00:03
Open the cmd as administrator and try: pip install -U scikit-learn. — seralouk, Jul 06 '17 at 09:02

Why are you using sklearn 0.13.1 when the latest version is 0.18? You are very out of date and probably have dependency issues.

If you want an easier life then install anaconda. All the package versions work together with no need to compile anything.

+1 came for suggesting Anaconda. For windows user or actually anyone doing mostly data analyses with Python that solves a lot of potential headaches. That said for webdev it's most likely create some headaches... – Kimmo Hintikka Mar 04 '17 at 14:46

Installing sklearn is enough for reading the data.Probably the file is not retrieved by your version of sklearn. Try to read the file from your drive

c:/Users/../site-packages/sklearn/datasets/data

directly and this can confirm the issue.

Typically the error

from ..utils import check_array
ImportError: cannot import name check_array

appears when there is a dependency version mismatch is there. To resolve the issue either a) update to the latest version of sklearn via pip or easy_install . Or manually install b) Create a Python virtual environment and try this. It will help you to manage the version specific depend libraries.

My two cents : Go for Anaconda or Enthought Python distributions if latest version of sklearn is okay. Else better to use virtualenv package in python to isolate the environments and avoid conflicts.

Happy Hacking
