Question

在Ubuntu 14.04中，我已经安装了基于https://dato.com/download/install-graphlab-create-command-line.html的Graphlab，它似乎工作正常。

但是，我在尝试使用推荐器模块时收到此错误：

import graphlab 
from graphlab.recommender import ranking_factorization_recommender

在第一行中，导入graphlab时没有任何错误。但是，第二行会导致此错误：

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last) 
<ipython-input-5-34df81ffb957> in <module>()
----> 1 from graphlab.recommender import ranking_factorization_recommender

ImportError: No module named recommender

如何解决问题？感谢

Answer 1

这只是命名空间问题。 recommender实际上存在于`toolkits模块中，所以这应该有效：

import graphlab
from graphlab.toolkits.recommender import ranking_factorization_recommender

Answer 2

Graphlab已经在__init__.py文件中为您导入了所有内容。

只是做：

from graphlab import ranking_factorization_recommender
from graphlab import <any_other_recommender>

以下是graphlab.__init__.py文件的摘录：

from graphlab.util import get_runtime_config
from graphlab.util import set_runtime_config

import graphlab.connect as _mt
import graphlab.connect.aws as aws
from . import visualization

import os as _os
import sys as _sys
if _sys.platform != 'win32' or \
    (_os.path.exists(_os.path.join(_os.path.dirname(__file__), 'cython', 'libstdc++-6.dll')) and \
    _os.path.exists(_os.path.join(_os.path.dirname(__file__), 'cython', 'libgcc_s_seh-1.dll'))):

    from graphlab.data_structures.sketch import Sketch
