这是我的代码请帮助。我是初学者。

    import pandas as pd
    import sklearn
    from sklearn.feature_selection import SelectFromModel
    from sklearn.ensemble import ExtraTreesClassifier
    from sklearn.metrics import confusion_matrix
    from sklearn.model_selection import train_test_split
    from sklearn import cross_validation

我正在使用最新版本的 Sklearn，但出现此错误

在 Windows 上:

Traceback (most recent call last): File "MalwareDetector.py", line 8, in from sklearn import cross_val_score ImportError: cannot import name 'cross_val_score' from 'sklearn' (C:\Users\richa\AppData\Local\Programs\Python\Python37-32\lib\site-packages\sklearn__init__.py)

在 Ubuntu 上:

Traceback (most recent call last): File "MalwareDetector.py", line 8, in from sklearn import cross_validation ImportError: cannot import name cross_validation

Answer 1

cross_validation自 0.18 版起已弃用。此模块将在 0.20 中删除。
请改用 sklearn.model_selection.train_test_split。

from sklearn.model_selection import train_test_split
