cudnnFindConvolutionForwardAlgorithm failed

Hey,

I'm getting the above error a couple of seconds after the first training epoch starts:

nClasses:   1000

==> doing epoch on training data:

Data set is prepared exactly as indicated in the README.md and cuda config is also operational. Has anyone ever come across a similar error running this ConvNet?

Cheers & Thanks,

Did someone find a solution?

Relates to GPU memory being full. Try with a smaller batch size.
