unknown Torch class <resnet.ImagenetDataset>

I see a similar problem as reported in #168
th main.lua -depth 50 -batchSize 256 -nGPU 4 -nThreads 8 -shareGradInput true -data /ImageNet2012/

Am I missing something basic here ? Any help ?

That shouldn't happen. Have you modified the fb.resnet.torch code? Are you running a recent version of Torch?

[antoajayraj]

No.. I had not modified the fb.resnet.torch code. and I am using the recent version of Torch

@antoajayraj We are using a power8 ( ppc64le ) and we are having the same problem. Are you using the same architecture?

[antoajayraj]

@pedropgusmao Yup.. i was using ppc64le.
Now I got it resolved by adding the current directory to LUA_PATH:

$ export LUA_PATH="$LUA_PATH;./?.lua"
$ cd multi-resnet/
$ th main.lua -netType multi-resnet -depth 200 -k 5 -batchSize 64 -nGPU 2 -nThreads 4 -dataset cifar10 -nEpochs 200

Thanks !!
