I am getting the following error when I import svm modules. I have installed scipy as per the instructions. Here is the code and error.

>>> 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，它是由SciPy的版本和scikit学习版本之间的不匹配造成的，你可以阅读的“依赖”部分为scikit学习版本0.13.1或任何其他版本在这里 。
