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

Question

The solution presented in this thread did not work for me:

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

I've tried conda install theano (for jupyter notebook) and despite installing perfectly I'm still getting the above error.

I'm using Python 3.6, Windows 7, Anaconda/Jupyter notebook, with a Nvidia 1070 GPU. Theano is version .9.0

The traceback is as follows:

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

UPDATE:

I uninstalled theano using pip3.6 and conda ( I had two versions) and then reinstalled with conda install theano

Now I'm getting this error:

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

ModuleNotFoundError: No module named 'theano'

Tried restarting Jupyter notebook as well, getting the No module named 'theano'

EDIT: Reinstalled theano a few times. I even restarted my computer. Still having this problem.

I see theano in the site-packages folder within the anaconda folder. So not understanding what the problem is.

The problem has reverted back to :

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

Thank you.

Answer 1

Ensure you are following the installation procedures from Theano Install

For me in a windows environment & Python 3.6 following did the trick

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

>>> conda install theano pygpu

Answer 2

For me it was a compiler problem that resulted from a wrong (unexpected) g++ version being used for compilation.

In addition to the m2w64-toolchain package (which includes a g++ compiler that is "highly recommended" for use with theano, cf. installation instructions), I had a cygwin instance installed whose g++.exe was pointed to in the windows system's PATH variable. During import theano, the cygwin version was used instead of the m2w64-toolchain version.

See also this discussion where I found the solution: https://github.com/Theano/Theano/issues/6004

Answer 3

For me, this was a numpy version issue. Once I reinstalled my numpy to version 1.13.1, it worked.

Note: Make sure to update also other packages that depend on numpy such as Scikit-learn, etc in a way to be compatible. The best way is to create an env just for deep learning.
