python - sklearn 无法导入名称 _ellipsoid

Question

在我的电脑上，sklearn 就像半年前一样工作，我已经停止使用它，现在不是了。 我在 program.py 中遇到导入语句问题:

from sklearn import tree

看起来很乱:

Traceback (most recent call last):   File "E:/DecisionModel.py", line 1, in <module>
    from sklearn import tree   File "C:\Users\AppData\Local\Programs\Python\Python35\lib\site-packages\sklearn\__init__.py", line 57, in <module>
    from .base import clone   File "C:\Users\AppData\Local\Programs\Python\Python35\lib\site-packages\sklearn\base.py", line 12, in <module>

    import scipy.special as special   File "C:\Users\AppData\Local\Programs\Python\Python35\lib\site-packages\scipy\special\__init__.py", line 643, in <module>
    from ._ellip_harm import ellip_harm, ellip_harm_2, ellip_normal   File "C:\Users\AppData\Local\Programs\Python\Python35\lib\site-packages\scipy\special\_ellip_harm.py", line 7, in <module>
    from ._ellip_harm_2 import _ellipsoid, _ellipsoid_norm ImportError: cannot import name '_ellipsoid'

一些有用的信息: 之前的错误是它无法导入我从 here 安装的 NUMPY_MKL。 .

您是否尝试重新安装 scikit-learn？如果您使用 pip，您可以尝试以下命令:

python -m pip install --upgrade pip
python -m pip install --upgrade --force-reinstall scikit-learn
