ValueError: too many boolean indices

[audy]

I'm getting this error:

try_milk/1.9.3 $ python bug.py 
Traceback (most recent call last):
  File "bug.py", line 14, in <module>
    learner.train(features, labels)
  File "/Users/b/.pythonbrew/pythons/Python-2.7/lib/python2.7/site-packages/milk/supervised/multi.py", line 120, in train
    model = self.base.train(features[idxs], (labels[idxs]==i).astype(int), **child_kwargs)

    train_out = names[train_out]
ValueError: too many boolean indices

When I run this code from the examples:

#!/usr/bin/env python

import milk.supervised.randomforest
import milk.supervised.adaboost
import milksets.wine
from milk.supervised.multi import one_against_one

weak = milk.supervised.randomforest.rf_learner()
learner = milk.supervised.adaboost.boost_learner(weak)
learner = one_against_one(learner)

features, labels = milksets.wine.load()

learner.train(features, labels)

Just fixed it.

Thanks for the excelent bug report. I am sorry it took so long, but I only got back home yesterday.
