update torch problem occured

[Sarah20187]

After update my torch use ./update.sh, I run the command below, and got the following error:
th ./main.lua mb slow -a predict -net_fname net/net_mb_slow_-a_train_all.t7 -left ../data/md/2005_2006/Wood2/view1.png -right ../data/md/2005_2006/Wood2/view5.png -disp_max 70

Did you update CUDNN to 5.1 also?

You can try disabling the cudnn optimization. Change the flag cudnn.benchmark=True in main.lua to False and see if that fixes the problem.

cudnn.benchmark true is why FindConvolutionForwardAlgorithm is being called.

I had similar problem and I think it is a memory issue.

Thank you for your reply! Finally I found this problem occurs because someone upgrade the cudnn to 5.0 on server. I fixed this problem by add dependencies in my home directory

@zhFuECL Hi, I am also working on this code for image dense matching. Can we talk about it a little bit? Here is my QQ: 1376519063
