Exception: ("We can't determine the cudnn version as it is not available",

[lawlite19]

I have installed cuda and cudnn, and I run THEANO_FLAGS='device=cpu, floatX=float32, nvcc.fastmath=True' /usr/bin/python iGAN_main.py --model_name outdoor_64, the error message is:

Thank you!

The code is only tested with an older Theano version as well as old GPUs and CUDNN. Could you run other Theano demo code such as this one?

mine is similar, I am on windows and i have this problem:

The code was developed around 2015. I am pretty sure it doesn't work with cudnn 5.1. See here for the Theano version.
