HI, @garythung

I run th train.lua, but met this error:

What's wrong with me?

My CUDA & Luarocks Package install is allright, may be..

@bemoregt did you solve it?? did u get the output??

@garythung please reply why this error is occuring

Hey guys, I don't work on this anymore so I won't be of too much assistance.

The error seems to be because of the number of classes (my fault). Try -numClasses 6 when you run the training, that should fix it.

Thanks a lot ~

Did it fix the error?

No. Please send the full command to run train.lua

Try th train.lua -numClasses 6
