Python-如何从 sklearn.tree 导入决策树分类器

Question

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? ps I have downloaded anaconda already, but not sure if it could work. Much Thanks!

Answer 1

You need to install the package Sklearn
