Can't run neural-style in GPU mode

My card is NVS 5200M and my CUDA version is 7.5. When I tried to use neural-style in GPU mode with this command:

th neural_style.lua -style_image picasso.jpg -content_image con.jpg -backend cudnn -cudnn_autotune -optimizer adam

it returned:

If the message turns out to be larger than 1073741824 bytes, parsing will be halted for security reasons.

I tried to lower the image_size to 100, to 10, and to 1, it still didnt work: it returned the same error.

The nvidia-smi command returns:

I dont know whether my GPU can use neural-style or not. On the NVIDIA webpage https://developer.nvidia.com/cuda-gpus, it says that my GPU is CUDA capable.
