CUDA 7.5 GPU backend test fail #203

Closed davorh closed 8 years ago

test fails with GPU backed. CPU backend works fine, latest github version is installed. Full output attached, error snip:

Are you using CuDNN (Cuda Neural Network library) version 5? If so, downgrade that to v4 and you should be good to go. The issue with CuDNN v5 is already open in a couple of places (which should probably be consolidated), here's one I posted: https://github.com/pluskid/Mocha.jl/issues/198

Also take a look at this related issue, if Mocha doesn't find the CuDNN v4 library you might need to checkout the latest master from the repo, or just manually apply the simple fix I referenced here: https://github.com/pluskid/Mocha.jl/issues/199

You should be able to continue using the Cuda v7.5 libraries, the problem here only relates to the CuDNN library specifically.

Yes, version 5. Tnx I'll use #199 :)
