Question

我正在尝试将数据集拆分为训练集和测试集。我尝试为此使用scikit-learn的train_test_split模块，将其导入为：

from sklearn.model_selection import train_test_split

将导致以下错误：

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-28-d05cc6ee7707> in <module>
----> 1 from sklearn.cross_validation import train_test_split

ModuleNotFoundError: No module named 'sklearn.cross_validation'

然后我在stackoverflow中找到了一些有关此的文章，他们说您应该使用以下代码导入该模块：

from sklearn.model_selection import train_test_split

再次使用

引起此问题：

---------------------------------------------------------------------------

ImportError: cannot import name '_safe_indexing' from 'sklearn.utils' (C:\Users\amir\Anaconda3\lib\site-packages\sklearn\utils\__init__.py)

有什么正确的方法可以导入吗？我应该怎么做？

Answer 1

关闭内核，然后重新启动。如果它不起作用，请停用anaconda，然后再次将其激活。再次运行它，它将运行。就我而言，我在运行时遇到了同样的问题-from imblearn.under_sampling import RandomUnderSampler

找不到scikit-learn train_test_split模块
