Question

想导入train_test_split以便将数据集分为测试数据集和训练数据集，但是发生导入错误

我尝试了所有这些，但没有用

conda upgrade scikit-learn
pip uninstall scipy
pip3 install scipy

pip uninstall sklearn
pip uninstall scikit-learn
pip install sklearn

未导入的代码

from sklearn.preprocessing import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X,y,test_size=0.2,random_state=0)

 from sklearn.preprocessing import train_test_split
Traceback (most recent call last):

  File "<ipython-input-3-e25c97b1e6d9>", line 1, in <module>
    from sklearn.preprocessing import train_test_split

ImportError: cannot import name 'train_test_split' from 'sklearn.preprocessing' (C:\ProgramData\Anaconda3\lib\site-packages\sklearn\preprocessing\__init__.py)

Answer 1

train_test_split不在preprocessing中，而是在model_selection和cross_validation中，所以您的意思是：

from sklearn.model_selection import train_test_split

或者：

from sklearn.cross_validation import train_test_split

导入错误-无法从'sklearn.preprocessing
