尝试导入sklearn模块时出错：ImportError：DLL加载失败：找不到指定的模块

Question

我尝试为机器学习项目进行以下导入：

from sklearn import preprocessing, cross_validation, svm
from sklearn.linear_model import LinearRegression

我收到此错误消息：

Traceback (most recent call last):
  File "C:/Users/Abdelhalim/PycharmProjects/ML/stock pricing.py", line 4, in <module>

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

请帮助我尝试一切，但无济于事。我也尝试了以下解决方案： ImportError：DLL加载失败：模块可升级

ImportError：DLL加载失败：找不到指定的模块

Answer 1

这条线指向科学。

from scipy.sparse.linalg import lsqr as sparse_lsqr

你可以试试：

pip uninstall scipy

pip install scipy

请享用！

Answer 2

您应该打开“C:\Python27\lib\site-packages\sklearn\utils\fixes.py”，然后编辑内容。您应该进行两项具体更改：

首先，将https://github.com/scikit-learn/scikit-learn/blob/74a9756fa784d1f22873ad23c8b4948c6e290108/sklearn/utils/fixes.py的内容复制并粘贴到文件“C:\Python27\lib\site-包\sklearn\utils\fixes.py”。

其次，将 if 行替换np_version < (1, 12, 0):为if np_version < (1, 12):。
