Error: attempt to index field 'CudaByteStorage about gvnn

[ankurhanda]

you need to have cutorch and cudnn and cunn all installed.

Thanks for your support, but even with all those rocks installed the problem occurs. I dont want you to debug my installation but it seems like that I did all right but does not work. I use lua5.2 instead of luaJIT could it be a problem?

It may be that you have to install older version of cudnn. This code was written in June 2016 or around that time. I think a lot of things have changed since then. What do you want to do with it? I can then recommend few things.

[marek094]

Ok, now I will try to build all from scratch again and than with older cudnn.

I am fascinated by your article [1] about Self-supervised learning. It looks like a great bootstrap for many real world problems. I am focusing in my thesis on generating disparity maps from scenes of tens copies of one object. So I would like to repeat your experiment and try to improve it of this domain-specific scenes.
