body: <p>Why the max_depth of every decision tree in my random forest classifier model are the same?
  I set the max_depth=30 of my RandomForestClassifier, and when I print each trees(trees = RandomForestClassifier.estimators_), I find every tree's max_depth are the same.</p>
  
  <p>I really don't know where is the problem and how it happnend.</p>
