  1. May I know how to import DecisionTreeClassifier from sklearn.tree as there is an error shown: ModuleNotFoundError: No module named 'sklearn'

  2. Also, every time when I want to import functions like pandas, I need to pip install them which is time-consuming. Is there any other methods to avoid installing each time for new importing function? p.s. I have downloaded anaconda already, but not sure if it could work. Much Thanks! enter image description here

  • "every time when I want to import ... I need to pip install them" - this shouldn't happen. The entire point of installing packages is to have them available without installing each time. The error with sklearn happens because Scikit-Learn is not installed: `pip install scikit-learn` – ForceBru Feb 12 '22 at 09:12

    If you are using `conda`, you may need to use it rather than `pip`. – rickhg12hs Feb 13 '22 at 03:57

  • Please [edit] your post to add code and data as text ([using code formatting](https://stackoverflow.com/editing-help#code)), not images. Images: A) don't allow us to copy-&-paste the code/errors/data for testing; B) don't permit searching based on the code/error/data contents; and [many more reasons](https://meta.stackoverflow.com/a/285557). Images should only be used, in addition to text in code format, if having the image adds something significant that is not conveyed by just the text code/error/data. See [mcve] on what code is required. – Adriaan Jan 17 '23 at 12:30

Just Re-install Anaconda with the latest version and use this code:

import pandas as pd
from sklearn.tree import DecisionTreeClassifier

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


model=DecisionTreeClassifier()
model.fit(X,y)
prediction=model.predict([[21,1],[22,0]])
prediction

You need to install the package Sklearn

  • OP already imports from `sklearn.tree`. This answer therefore is either useless, or severely underexplained. – Adriaan Jan 17 '23 at 12:30
