evaluation.lua:103: attempt to index field 'val' (a nil value)

[tekeburak]

I am getting the error below while I was trying to run evaluation.lua. There is no gen/chalearn15.t7 file to load using torch.load; but in evaluation code there is a line like that. Any idea @gaobb or @YVanlaer. Thank you for your help.
