如何导入sklearn？

Question

[我已经使用pip3安装了Sklearn 0.0，并安装了Scikit-learn 0.22，当我去（导入sklear）或（从sklearn.model_selection导入train_test_split）时，出现以下错误：

Traceback (most recent call last):
  File "C:/Users/khaled.abdalla/PycharmProjects/Py_Project1/RegressionAnalysis.py", line 6, in <module>
    from sklearn.model_selection import train_test_split
  File "C:\Users\khaled.abdalla\PycharmProjects\Py_Project1\venv\lib\site-packages\sklearn\__init__.py", line 76, in <module>
    from .utils._show_versions import show_versions

    from ._openmp_helpers import _openmp_parallelism_enabled
ImportError: DLL load failed: The specified module could not be found.

Answer 1

您还必须安装Numpy和Scipy软件包。使用http://www.lfd.uci.edu/~gohlke/pythonlibs/中的非官方安装程序

Answer 2

请注意，您不应运行pip3 install sklearn，而应运行pip3 install scikit-learn。 sklearn是别名，不应使用。您可以参考文档以在其中安装scikit-learn：https://scikit-learn.org/stable/install.html

要删除别名包，请使用pip3 uninstall sklearn。
