"cannot convert 'struct THFloatTensor *' to 'struct THCudaTensor *'" when running the single machine cam demo

[yosit]

Hi, I'm running on a mac 15" with nvidia. Trying to run with gpu yields out of memory. Running without a gpu yields this:

qlua webcam/single_machine_demo.lua -gpu -1 -use_cudnn 0

Hi yosit, have you resolved this? I got the same "cannot convert" problem. Thanks!
