./checkpoints.lua:52: attempt to call method 'clearState' (a nil value) #2

1) Great work, a milestone! Never seen top5 go down so seamlessly.

2) little bug:

th main.lua -netType densenet -depth 40 -dataset cifar10 -batchSize 64 -nEpochs 300 -optnet true
...
 | Test: [1][157/157]    Time 0.021  Data 0.000  top1  87.500 ( 83.420)  top5  50.000 ( 55.870) 
 * Finished epoch # 1     top1:  83.420  top5:  55.870
 * Best model   83.42   55.87   

./checkpoints.lua:52: attempt to call method 'clearState' (a nil value)

seems to be caused by -optnet true

liuzhuang13 commented 8 years ago

Yeah we recommend to install optnet first.

We haven't see bugs about the method 'clearState', this part was written by fb.resnet.torch. Check if you can train resnet using fb.resnet.torch.

In our experiment with DenseNet (L=40, k=12), the top 1 error rate on CIFAR-10+ after one epoch is typically ~50%, so there might be some other bugs.

Thanks

Maybe try updating/reinstalling fb.resnet.torch? There have been changes recently:)
