resnet models don't produce results

[agilebean]

Hi, I have tried using the ResNet models for torch provided by the Facebook distribution:

th slow_neural_style.lua -gpu 0 -use_cudnn 1 
-content_image /home/rstudio/sync-fns/input/jessica_alba1.jpg 
-style_image /home/rstudio/sync-fns/styles/cloth5.jpg 
-output_image /home/rstudio/sync-fns/output/resnet101-1-cloth5.png 
-num_iterations 1000 -print_every 10 -save_every 500 
-loss_network /home/rstudio/resnet-101.t7 
-preprocessing resnet

Unfortunately, they give me pictures only containing noise:

This is strange - using exactly the same code with the vgg16 model renders good results:

Do I have to convert the t7 model somehow??

I found this in the log - maybe it gives a hint.
