‘在theano安装过程中没有名为nose_parameterized`的模块

Question

目前，我正试图在我的ubuntu16.04系统上安装theano，并提供cuda支持。在我尝试测试安装之前，安装过程本身进行得很顺利：

python -c "import theano; theano.test()"

产出的最后几行是：

======================================================================
ERROR: Failure: ImportError (No module named nose_parameterized)

    from nose_parameterized import parameterized
ImportError: No module named nose_parameterized

Ran 408 tests in 13.085s

FAILED (SKIP=26, errors=80)

在这些代码之前大约有20个块，似乎不同的测试在堆栈跟踪中的前3行都失败了。出现最终结果的代码如下(添加行号)：

411. # FIXME: to support module.name names,
412. # do what resolve-name does and keep trying to
413. # import, popping tail of module into addr.call,
414. # until we either get an import or run out of
415. # module parts
416. try:
417.     module = self.importer.importFromPath(
418.     addr.filename, addr.module)
419. finally:
420.     self.config.plugins.afterImport(
421.     addr.filename, addr.module)

在寻找解决方案时，我偶然发现：

运行鼻测试错误

我尝试了在那里提出的解决方案：

sudo pip install nose-parameterized

然而，这没有任何效果。有人知道还会是什么原因导致这个错误吗？

编辑:所以我重新安装了theano，以使问题更容易重现。我使用找到这里的说明安装了theano，所以我使用了：

sudo apt-get install python-numpy python-scipy python-dev python-pip python-nose g++ libopenblas-dev git  
sudo pip install Theano  

然后我用：

nosetests theano

输出的最后几行内容与前面几乎相同：

======================================================================

编辑2:我认为这可能是一个python版本的问题。当我尝试：

python -V  

我得到：

Python 2.7.12 :: Anaconda 4.2.0 (64-bit)

并且存在以下文件夹：

/usr/local/lib/python2.7/dist-packages/nose_parameterized

据我所知，这不应该是个问题。然而，当我尝试：

python2.7 -c "import nose_parameterized"  

我得到：

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named nose_parameterized

Answer 1

发现问题时，阿纳康达正在寻找自己的文件夹。为了解决这个问题，我做了：

conda install nose-parameterized

Answer 2

以下几点对我来说是可行的：

pip install nose-parameterized
