python - 导入sklearn时出错

Question

使用 pip install -U scikit-learn 安装 scikit-learn 后，我无法调用 import sklearn:

>>> import sklearn
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\sklearn\__init__.py", line 57, in <module>
  from .base import clone
File "C:\Python27\lib\site-packages\sklearn\base.py", line 9, in <module>
  from scipy import sparse
File "C:\Python27\lib\site-packages\scipy\sparse\__init__.py", line 214, in <module>
  from .csr import *
File "C:\Python27\lib\site-packages\scipy\sparse\csr.py", line 13, in <module>
  from ._sparsetools import csr_tocsc, csr_tobsr, csr_count_blocks, \
ImportError: DLL load failed: %1 is not a valid Win32 application.

如何克服这个错误？

您可以尝试使用 Anaconda 创建虚拟环境，然后通过 conda 而不是 pip 安装 sklearn

conda create -n yourenvname python=3.5 anaconda
conda install -n yourenvname sklearn
