NameError: name 'tree' is not defined
Hey I'm new to Python and I am trying to follow along with a tutorial but I get this error:
NameError: name 'tree' is not defined.
The objective is obviously for the program to determine whether the fruit is an apple or orange based on the input of features. I'm using Python 3.6 with the spyder editor on Win 10. I'm sure it's something simple, thanks for any help!
# -*- coding: utf-8 -*- """ Spyder Editor This is a temporary script file. """ # features = [[140, "smooth"], [130, "smooth"], [150, "bumpy"], [170, "bumpy"]] # labels = ["apple", "apple", "orange", "orange"] features = [[140, 1], [130, 1], [150, 0], [170, 0]] labels = [0, 0, 1, 1] # We build a "Decision Tree" yes/no -> yes/no # clf means classifier clf = tree.DecisionTreeClassifier() # Think of "fit" as "find patters in data" clf = clf.fit(features, labels) print (clf.predict([[160, 0]]))
Add this to the top of your code:
from sklearn import tree
This is assuming that you are studying machine learning.

I tried this
from sklearn import tree it does not work on my system.
Then I tried this
from sklearn.tree import DecisionTreeClassifier and worked.
This is after installing
sklearn of course.

- You have to import some module. It is probably written in the tutorial which.
- I downloaded anaconda which must include sklearn because it worked after I did the import. Thanks a lot @BoobyTrap, cant believe I didn't see that.
