Error attempt to index field 'THNN' (a nil value)

[ghost]

I am running this code on my on dataset with 826 classes using the following command: th main.lua -data myDataset -netType vgg -batchSize 12 -nClasses 826 The type of the VGG network I'm using is 'E' after the first epoch I decide to try out by myself how the model is performing using this code:

img = testHook(224, "myImage.jpg")
model = torch.load("model_1.t7")
if img:dim() == 3 then
   img = img:view(1, img:size(1), img:size(2), img:size(3))
end
predictions = model:forward(img:cuda())

I'm getting this error

Error attempt to index field 'THNN' (a nil value)

I do not know where this error is coming from...

Is there any way to fix that? Is it an error from any luarocks installation?

Thanks in advance

looks like you forgot to add require 'cunn'
