I run with the following command:

th main.lua -data /devData/BenchmarkData/ILSVRC2012_resize  -netType overfeat

But I got the following error messages. Any suggestions? Thanks.

Requirements section in readme:

git clone https://github.com/torch/nn && cd nn && git checkout getParamsByDevice && luarocks make rocks/nn-scm-1.rockspec

It works. Thanks. I can run the demo now. But the Volatile GPU-Util of Tesla K40c is almost always 0%. Is it normal?
