我正在编写我的第一个机器学习程序。我是全新的，我在 pycharm 中编写 python 代码，但出现如下错误。 我什至找不到任何初学者教程，也许大多数人都不知道
ModuleNotFoundError: No module named 'scipy'
from sklearn import tree
features = [[140,1],[130,1],[150,0],[170,0]]
labels = [0,0,1,1]
clf = tree.DecisionTreeClassifier()
clf = clf.fit(features,labels)
print(clf.predict([[150, 0]]))
Traceback (most recent call last): File "C:/Users/LENOVO/PycharmProjects/MyPython/MyPyton.py", line 1, in from sklearn import tree File "C:\Users\LENOVO\AppData\Local\Programs\Python\Python36\lib\site-packages\sklearn__init__.py", line 134, in from .base import clone File "C:\Users\LENOVO\AppData\Local\Programs\Python\Python36\lib\site-packages\sklearn\base.py", line 10, in from scipy import sparse ModuleNotFoundError: No module named 'scipy'
