Theano: AttributeError: module 'theano‘没有属性'gof’

Question

这个帖子中提出的解决方案对我不起作用：

Import theano gives the AttributeError: module 'theano' has no attribute 'gof'

我已经尝试过conda install theano (适用于jupyter笔记本)，尽管安装得很好，我仍然收到上面的错误。

我使用的是Python 3.6，Windows 7，Anaconda/Jupyter notebook，Nvidia 1070 GPU。Theano是.9.0版本

回溯如下：

AttributeError: module 'theano' has no attribute 'gof'

更新：

我使用pip3.6和conda卸载了theano (我有两个版本)，然后用conda install theano重新安装

现在我得到了这个错误：

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-6-3397704bd624> in <module>()
----> 1 import theano

ModuleNotFoundError: No module named 'theano'

也尝试重新启动Jupyter笔记本电脑，获取No module named 'theano'

编辑:重新安装了theano几次。我甚至重启了我的电脑。仍然有这个问题。

我在anaconda文件夹的site-packages文件夹中看到了theano。所以不知道问题出在哪里。

问题又回到了：

AttributeError: module 'theano' has no attribute 'gof'

谢谢。

Answer 1

对我来说，这是一个笨拙的版本问题。一旦我重新安装我的numpy到版本1.13.1，它就可以工作了。

注意:请确保以兼容的方式更新其他依赖numpy的包，如Scikit-learn等。最好的方法是创建一个用于深度学习的env。

Answer 2

对我来说，这是一个编译器问题，它是由于编译时使用了错误的(意外的) g++版本造成的。

除了m2w64-toolchain包(其中包括一个“强烈建议”与theano一起使用的g++编译器，请参阅：installation instructions)，我安装了一个cygwin实例，它的g++.exe在windows系统的PATH变量中指向。在import theano期间，使用cygwin版本而不是m2w64-toolchain版本。

另请参阅我找到解决方案的讨论：https://github.com/Theano/Theano/issues/6004

Answer 3

确保您遵循Theano Install中的安装过程

对我来说，在windows环境中，Python3.6就做到了

>>> conda install numpy scipy mkl-service libpython m2w64-toolchain nose sphinx pydot-ng git

>>> conda install theano pygpu
