pyhotn ipython

pythonで以下を実行しようとしたら
no moduleと出ました。moduleはpipで入れてあります。
解決策などあるでしょうか。
環境は　google　colaboratelyです。

from Ipyton.display import Image 
from sklearn.externals.six import StringIO 
dot_data = StringIO() 
tree.export_graphviz(clf, out_file=dot_data)
graph = pydotplus.graph_from_dot_data(dot_data.getvalue()) 
Image(graph.create_png())
