When running the Quick example of the MLP on the MNIST data I am getting the following error when running on Python 3.5:
Using gpu device 0: GeForce GT 650M (CNMeM is disabled, cuDNN not available)

Forgot to update the example! MNIST is now 2D by default, this example assumes 1D. You have to initialize MNIST now with flatten=True argument.
marked this as solved
That fixed the issue! Thank you.
