I am using jupyter installed via Anaconda3. i cannot import DecisionTreeClassifier and getting the below error. Python version installed in Ananconda - 3.7.3.

Can someone help me here?

import pandas as pd
from sklearn import tree 

music = pd.read_csv('music.csv')
X = music.drop(columns=['genre'])
y = music['genre']

modl = tree.DecisionTreeClassifier()
modl.fit(X,y)

predictions = modl.predict([[21,1],[22,0]])
predictions

Error Message:
