ModuleNotFoundError: No module named 'sklearn.lda'

from sklearn.lda import LDA

from sklearn.qda import QDA

一直报错：ModuleNotFoundError: No module named 'sklearn.lda'。然后注释掉LDA那行，又报错No module named 'sklearn.qda'。求解决方案！先谢各位了！

嗯……你有安装sklearn嘛

就是那个在命令行pip install sklearn

应该是版本更新问题吧，试试：

from sklearn.discriminant_analysis import LinearDiscriminantAnalysis as LDA
from sklearn.discriminant_analysis import QuadraticDiscriminantAnalysis as QDA
