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 "help", "copyright", "credits" or "license" for more information. >>> import theano Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python2.7/dist-packages/theano/__init__.py", line 74, in from theano.printing import pprint, pp File "/usr/local/lib/python2.7/dist-packages/theano/printing.py", line 35, in if pd.find_graphviz(): AttributeError: 'module' object has no attribute 'find_graphviz'
What could be the issue, and how to fix it?
I use Theano 0.8.2 on Ubuntu 14.04.4 LTS x64 with Python 2.7.6 x64.
I unsuccessfully tried:
sudo apt-get install -y graphviz libgraphviz-dev

In pydot 1.2.x version,find_graphviz function have been deprecated. To fix this issue, you should install pydot 1.1.0 version here https://github.com/erocarrera/pydot/tree/v1.1.0 . And it is work for me. May help.

I solved by installing pydot-ng --> $ pip install pydot-ng

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.

I solved it by using
sudo pip install graphviz sudo apt-get install graphviz
with the pydot version 1.2.3 works fine
