I am running on a local machine in a conda virtual enviornment. I have CUDA 8 installed and cuDNN 6 for cuda8. I don’t want to downgrade if I don’t have to. I understand that the fast.ai lessons rely on python 2, so I have that configured in the conda env that I launch jupyter notbook from.
I tried with tensorflow installed as the back end, which had the same base error, that it couldn’t find cuDNN 5, whih makes sense because I have version 6. I tired to run theano in case it didn’t need cuDNN, but now not only does it still not find the right cuDNN, it doesn’t actually use theano?
I create a .keras/keras.json and theanorc files as shown in the videos.
those files are
{
"image_dim_ordering": "th",
"epsilon": 1e-07,
"floatx": "float32",
"backend": "theano"
}
and
[global]
floatX = float32
device = gpu0
[nvcc]
fastmath = True
[cuda]
root=/usr/local/cuda/
the jupyter notebook error is from line:
from imp import reload
import utils; reload(utils)
from utils import plots
and is:

I also tried making a sym link:
Try 2:
If however I try to use python 3 instead, which as an up to date tensorflow etc and shouldn’t ask for cudnn 5, I get the cPickle error which is part of python2 only (or so forum conversations have led me to believe).
Try3:
I have even tried using a new conda env that ONLY has theano installed (no tensorflow) and even setting “KERAS_BACKEND=theano” from bash prior to starting, but it still trys theano partially crashes, says it is using tensorflow backend, then crashes saysing no tensorflow.
I just want to join this cool deep learning club and just can’t get started… 
I’m using 
Thank you so much!!
