在安装 theano 期间没有名为 nose_parameterized 的模块
`No module named nose_parameterized` during theano installation
目前我正在尝试在我的 ubuntu 16.04 系统上安装 theano 并支持 cuda。安装过程本身进行得很顺利,直到我尝试测试安装:
python -c "import theano; theano.test()"
输出的最后几行是:
======================================================================

这些之前有大约 20 个块,似乎是不同的测试在堆栈跟踪中完全相同的前 3 行失败。最后出现的代码如下所示(添加了行号):
411. # FIXME: to support module.name names,
412. # do what resolve-name does and keep trying to

在寻找解决方案时,我遇到了:
我尝试了那里提出的解决方案:
sudo pip install nose-parameterized
然而,这没有效果。有谁知道还有什么可能导致此错误?
编辑:所以我重新安装了 theano 以使问题更容易重现。我使用 here 中的说明安装了 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
然后我用了:
nosetests theano
这个输出的最后几行和前面几乎一样:

编辑 2:我认为这可能是 python 版本问题。当我尝试时:
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
所以,据我所知,这应该不是问题。但是当我尝试时:
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
发现问题,anaconda 正在自己的文件夹中查找。所以为了解决,我做了:
conda install nose-parameterized
以下对我有用:
pip install nose-parameterized
