How to compare if two sklearn estimators are equals?
<p>I have two sklearn estimators and want to compare them:</p>

<pre><code>import numpy as np
from sklearn.tree import DecisionTreeClassifier

X, y = np.random.random((100,2)), np.random.choice(2,100)    
dt1 = DecisionTreeClassifier()
dt1.fit(X, y)
dt2 = DecisionTreeClassifier()
dt3 = sklearn.base.copy.deepcopy(dt1)
</code></pre>

<p>How can I compare classifiers so that dt1 != dt2, dt1 == dt3?</p>
