from sklearn import svm importterror:无法导入名称lsqr

Question

当我导入svm模块时，我得到以下错误。我已经按照说明安装了scipy。下面是代码和错误。

>>> from sklearn import svm
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
  File "/root/.local/lib/python2.6/site-packages/sklearn/svm/__init__.py", line 13, in <module>
    from .classes import SVC, NuSVC, SVR, NuSVR, OneClassSVM, LinearSVC
  File "/root/.local/lib/python2.6/site-packages/sklearn/svm/classes.py", line 3, in <module>
    from ..linear_model.base import LinearClassifierMixin, SparseCoefMixin
  File "/root/.local/lib/python2.6/site-packages/sklearn/linear_model/__init__.py", line 12, in <module>
    from .base import LinearRegression
  File "/root/.local/lib/python2.6/site-packages/sklearn/linear_model/base.py", line 23, in <module>
    from scipy.sparse.linalg import lsqr
ImportError: cannot import name lsqr

我也遇到了这个问题，这是由于scipy版本和scikit-learn版本不匹配造成的，你可以在这里阅读scikit-learn 0.13.1版本或任何其他版本的'Dependency'部分
