Error using sklearn.dataset

Question

I am trying to visualize some data. However, I am receiving the following error:

Traceback (most recent call last): File "/Users/usrname/PycharmProjects/MachineLearning/dddd.py", line 4, in <module> from sklearn.datasets import load_iris File "/usr/local/lib/python2.7/site-packages/sklearn/__init__.py", line 32, in <module> from .base import clone File "/usr/local/lib/python2.7/site-packages/sklearn/base.py", line 10, in <module> from scipy import sparse ImportError: No module named scipy

Below, there is the code to visualize the data.

from matplotlib import pyplot as plt from sklearn.datasets import load_iris import numpy as np # We load the data with load_iris from sklearn data = load_iris() features = data['data'] feature_names = data['feature_names'] target = data['target'] for t,marker,c in zip(xrange(3),">ox","rgb"): # We plot each class on its own to get different colored markers plt.scatter(features[target == t,0],features[target == t,1],marker=marker,c=c)

I am using the the Python 2.7, Mac OS "Mavericks".

How did you install sklearn? It evidently requires scipy, which you may also need to install. — jonrsharpe

And can you run from scipy import sparse directly in the interpreter? — jonrsharpe

Sorry, do you mean you can't try, or it gives the same error? If the latter, you will have to try reinstalling scipy, as sklearn won't work without it — jonrsharpe

Check if the sckit-learn is working properly or not.

 nosetests -v sklearn

if it shows error try installing first Scipy by

pip install git+http://github.com/scipy/scipy/
