Problems running the image example (Python 2.7.10, PyEnv, Xubuntu 14.04 64bit)

[samuell]

JFYI, I'm getting the following error when trying to execute the models/image/mnist/convolutional.py example (Python 2.7.10 in PyEnv, on Xubuntu 14.04, 64bit):

[samuel site-packages]$ pwd

[samuel site-packages]$ python tensorflow/models/image/mnist/convolutional.py

ImportError: /home/samuel/.pyenv/versions/2.7.10/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so: undefined symbol: PyUnicodeUCS4_FromStringAndSize

Will see if I can figure out something, but thought to report in the meanwhile.

[samuell]

Ah, great description of the problem here.

[ebrevdo]

For now, you can build your own pip package via instructions here; see "Create the pip package and install". Let us know if that doesn't work.

Please re-open if there's something left to diagnose here!

I'm seeing what might be a related error:

_pywrap_tensorflow.so: undefined symbol: cudnnCreate

My apologies, I was simply missing cudnn. :/

@FreakTheMighty
I have the same problem,but I don't understand what's your mean'My apologies, I was simply missing cudnn. :/' ,could express more clearly?
