Image-matching cudnn getHandle problem

[colettedog]

I am new to Torch and trying to follow your sample to learn about image matching.
I installed cuDNN and torch. The default torch installation installs luajit. I am trying to run the
arc-robot-vision/image-matching/test.lua
the code works until it try to call DataLoader (.....
it stops with the following error message, any help is appreciated.

Hello, cuDNN requires a GPU with CUDA compute capability 3.x or higher.
The error message CUDNN_STATUS_ARCH_MISMATCH suggests your GPU does not support it.

Hi Andy, Thanks. I am using an existing gt730 card. It was there with the pc. It is old and cheap. I will upgrade to a more capable one. Thank you for your reply. Ken lee
