fig 9.12; fig_rrlyrae_treevis.py and sklearn.tree.DecisionTreeClassifier

[richardgmcmahon]

I am using:

sklearn.version: 0.16.1
astroML.version: 0.3

File "fig_rrlyrae_treevis.py", line 242, in
random_state=0, criterion='entropy')
TypeError: init() got an unexpected keyword argument 'compute_importances'

I added these lines to fix my fork:

# in 0.14+ Setting compute_importances=True is no longer required. 
try:
  # version < 0.14
 clf = DecisionTreeClassifier(compute_importances=True,
                             random_state=0, criterion='entropy')
except:
  # version 0.14+
  clf = DecisionTreeClassifier(
                             random_state=0, criterion='entropy')

Thanks – there have been a number of changes to the scikit-learn API in the last year or so. I plan to update those in the next release.
