New version without Squeeze.lua causes error

[ghost]

Hi:

The previous version using Squeeze.lua works fine.
I would like to test sample.lua but it does not work with the previous version.

I'm new to lua/torch and I would like to sample from this model as per karpathy's original.

When I run the new version without Squeeze.lua I get the following error which is referencing 'Squeeze':

Is there another switch I should set to fix this?

Thanks,

Try updating your nn package.

Thanks for getting back to me. I ran luarocks list:
nn
scm-1 (installed) - /home/pixelhead/torch/install/lib/luarocks/rocks
ran again: luarocks install nn
same nn-scm-1.rockspec but when running main.lua a different error referencing 'TestSuite':

Should I update all modules listed under "luarocks list" ??? I'm new to torch/lua. I have karpathy's version including sample-beam.lua running without a problem and would like to compare sampled output from your program.

Can you try updating torch/cunn too?

luarocks install torch
luarocks install cunn

It worked for me when I installed the latest versions.

Thanks. That worked.

Cheers
