I've been getting the following error with django:

Exception Type: ImportError
Exception Value:    No module named sparse

The importerror comes from:

from sklearn.svm.sparse import LinearSVC
from nltk.classify.scikitlearn import SklearnClassifier

To solve this I'm trying to install the sparse module for scikit-learn via the following:

sudo easy_install scikits.sparse

But I am getting this error:

no previously-included directories found matching 'doc/_build'
warning: no previously-included files matching '*~' found anywhere in distribution
warning: no previously-included files matching '*.so' found anywhere in distribution
warning: no previously-included files matching '*.pyc' found anywhere in distribution
clang: error: no such file or directory: 'scikits/sparse/cholmod.c'
clang: error: no input files
error: Setup script exited with error: command 'clang' failed with exit status 1

How can I solve this problem?

Thanks.

改变

from sklearn.svm.sparse import LinearSVC

至

from sklearn.svm import LinearSVC

忘记了scikits.sparse，这与 scikit-learn 无关。该sklearn.svm.sparse模块在几个版本前已从 scikit-learn 中删除。

对于任何对安装 scikits.sparse 特别感兴趣的人。我在 Mac OS X 10.9 中遇到了麻烦。问题与 setuptools 根据您是否安装了 Cython 和 Pyrex 做出假设有关。

一个解决方案，当然不是最好的解决方案（对我有用）是安装 Pyrex。对于 macports 用户：

sudo port install py27-pyrex

安装稀疏套件。

编辑 setup.py 文件，使 ext_modules 的值如下：

ext_modules = [
    Extension("scikits.sparse.cholmod",
              ["scikits/sparse/cholmod.pyx"],
              libraries=["cholmod"],
              include_dirs=[np.get_include(), "path/to/sparsesuite/include"],
              library_dirs=["path/to/sparsesuite/lib"]
              ),
    ]

对我来说，SparseSuite 的包含和库目录是usr/local/include和/usr/local/lib。

在scikits/sparse/cholmod.pyx文件中编辑以下行：

cdef extern from "sparsesuite/cholmod.h":

至

cdef extern from "cholmod.h":

然后尝试再次安装 scikits.sparse。应该管用。
