Thanks for pointing this out. Maybe a recent change in nn broke something.
I'll check that in 1h and I'll come back to you

For the moment, nn doesn't support the groups option (which is necessary for alexnet model to run).
I'll update the README, but in the meanwhile, you can fix it by using the cudnn backend in loadModel (pass cudnn as a second argument.

Thanks! Load in cudnn mode solves the error.
