Question

目前我正在尝试使用cuda支持在我的ubuntu 16.04系统上安装theano。在我尝试测试安装之前，安装过程本身进展顺利：

======================================================================
ERROR: Failure: ImportError (No module named nose_parameterized)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/myUser/anaconda2/lib/python2.7/site-packages/nose/loader.py", line 418, in loadTestsFromName

  File "/home/myUser/anaconda2/lib/python2.7/site-packages/theano/tests/unittest_tools.py", line 7, in <module>
    from nose_parameterized import parameterized
ImportError: No module named nose_parameterized

----------------------------------------------------------------------
Ran 408 tests in 13.085s

FAILED (SKIP=26, errors=80)

输出的最后几行是：

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)

这些前面有大约20个块，看起来不同的测试在堆栈跟踪中完全相同的前3行失败。最终发生的代码如下所示（添加了行号）：

sudo pip install nose-parameterized

在寻找解决方案时，我遇到了：
concat
我尝试了那里提出的解决方案：
sudo apt-get install python-numpy python-scipy python-dev python-pip python-nose g++ libopenblas-dev git sudo pip install Theano
但这没有效果。有谁知道还有什么可能导致这个错误？

编辑：所以我重新安装了theano，使问题更具可重复性。我使用Error running nosetests找到的说明安装了theano，所以我使用了：

nosetests theano

然后我用了：

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

Ran 457 tests in 160.608s

FAILED (SKIP=24, errors=95)

此输出的最后几行几乎与之前相同：

python -V

编辑2：我认为这可能是一个python版本的问题。当我尝试：

Python 2.7.12 :: Anaconda 4.2.0 (64-bit)

我明白了：

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

存在以下文件夹：
python2.7 -c "import nose_parameterized"
所以，就我所见，这不应该是一个问题。但是，当我尝试：

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

我明白了：

{{1}}

Answer 1

发现问题，anaconda正在寻找自己的文件夹。所以要解决，我做了：
conda install nose-parameterized

Answer 2

以下对我有用：

pip install nose-parameterized

`在安装期间没有名为nose_parameterized的模块
