我想对某些数据执行LDA,因此遵循此示例:
然而,尝试:
from sklearn.discriminant_analysis import LinearDiscriminantAnalysis
我收到了导入错误。嗯,也许这是一个新功能,我想。所以我通过conda更新scikit-learn从0.15.2到0.17。但现在我甚至无法导入sklearn:
import sklearn
RuntimeError: module compiled against API version a but this version of numpy is 9
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "//anaconda/lib/python2.7/site-packages/sklearn/__init__.py", line 57, in <module>
from .base import clone

from scipy import sparse

from .csr import *
File "//anaconda/lib/python2.7/site-packages/scipy/sparse/csr.py", line 13, in <module>
from ._sparsetools import csr_tocsc, csr_tobsr, csr_count_blocks, \
ImportError: numpy.core.multiarray failed to import
我尝试使用pip和conda更新numpy和scipy无济于事。然后,我通过以下方式尝试完全干净地重新安装anaconda:
rm -rf ~/anaconda
以及随后从http://docs.continuum.io/anaconda/install#anaconda-install
下载.pkg我仍然得到同样的错误。这是我的操作系统和包装细节:
Mac OSX 10.5.2
bash-3.2$ conda -V
conda 3.18.6
scipy==0.16.0
numpy==1.9.1
scikit-learn==0.17
最后一个通过pip冻结,因为我无法导入它。我在这里疯了。任何帮助非常感谢。
答案 0 :(得分:0)
尝试:
conda install numpy=1.10.1
我之前遇到过module compiled against API version a but this version of numpy is 9
错误,这为我解决了。
