from sklearn import DecisionTreeRegressor >> ImportError

(1) Running Windows 8 (2) Downloaded and installed, Anaconda for Windows, PYTHON 2.7

(3) From Anaconda Prompt:

conda install scikit-learn
Fetching package metadata: ....
Solving package specifications: .....................
All requested packages already installed.
packages in environment at C:\Users\Joey\Anaconda2:
scikit-learn              0.17                np110py27_1

(4) Launched Spyder

(5) This is ok, and package is found.

import sklearn

(6) Tab completion (in Spyder) for sklearn, shows:

sklearn.base
sklearn.clone
sklearn.externals
sklearn.re
sklearn.setup_module
sklearn.sys
sklearn.utils
sklearn.warnings

(6) Therefore, when running a snippet as found in http://scikit-learn.org/stable/ example.

from sklearn import DecisionTreeRegressor
Traceback (most recent call last):

  File "<ipython-input-2-5aa62260685f>", line 1, in <module>
    from sklearn import DecisionTreeRegressor

ImportError: cannot import name DecisionTreeRegressor

(7) Earlier, I noticed the same behavior using Enthought Canopy and also couldn't get scikit to work there either. As a result, I uninstalled every Python program and IDE I could find to try and clean my system before attempting Anaconda, as described above. I looked at many other posts and still could not get my system to work properly and suspect there's path, library, or version issue.

decision tree algorithm is a module under Sklearn.tree Try and import it in this manner, it should work

scikit-learn is well documented. Here is the link for the documentation.

Right way is:

from sklearn.tree import DecisionTreeRegressor

sklearn.version = 0.17
