bad argument #1 to 'topk'

[bemoregt]

Hi, @zpao @iassael @maraoz @achao @gfosco

I have met this error:

./train.lua:137: bad argument #1 to 'topk' (k not in range for dimension

What's wrong with me?

Thanks at any rate...

You must be retraining for less then 5 classes, then this diff should work for you:

diff --git a/train.lua b/train.lua
