Importing theano: AttributeError: 'module' object has no attribute 'find_graphviz'

Question

When I run import theano in Python, I get the following error message:

Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type          


        

Answer 1

For some reason, the Python module pydot was creating the issue:

Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> import pydot
>>> pydot.find_graphviz()
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'module' object has no attribute 'find_graphviz'

I was using pydot 1.2.2.

I uninstalled it using sudo pip uninstall -y pydot, and I then was able to successfully import theano.
