This is the error I keep running into whenever I try to install cutorch. The weird thing is that require 'cutorch' works fine, but require 'cunn' or 'cunnx' says that 'cutorch' is a dependency and needs to be installed, and then this happens. Any help to fix this is much appreciated.

Can you please specify your OS?
Also, can you reinstall torch and cutorch with

luarocks install torch

luarocks install cutorch

OS is Ubuntu 12.04.4 LTS.

I installed Torch by following the instructions here: https://github.com/clementfarabet/torchinstall/blob/master/install-torch

I do not have luarocks installed. Do you want me to uninstall whatever I installed and reinstall using the luarocks method?

[soumith]

oh wow, can you please use https://github.com/torch/torch7/wiki/Cheatsheet for any and all instructions.

That repo you installed from is sooo old and I have no clue what it has.

How did you find that repo at all?

[Riddhiman Dasgupta]

OK, I removed all existing Torch and Lua files and folders, and reinstalled everything using the instructions over at the cheatsheet.

All modules installed correctly using luarocks, and I can even see them using luarocks list.

However, when I start Torch using th, and try to load a module, this is what I am getting currently:

th> require 'cutorch'

[string "require 'cutorch'"]:1: loop or previous error loading module 'cutorch'

stack traceback:

[C]: in function 'require'

[string "require 'cutorch'"]:1: in main chunk

[C]: in function 'xpcall'

                                                                      [0.0001s]

This is happening for all modules. What did I do wrong?

did you use the clean-old.sh script to cleanup? https://github.com/torch/ezinstall/blob/master/clean-old.sh

Can you just try a locally contained installed using this: https://github.com/soumith/torch-distro

I am not sure if there are system files that are conflicting still. This locally contained install will give you a torch that is only fully installed into this folder and nowhere else.

[Riddhiman Dasgupta]

I had installed everything locally. I'll try to use the clean-old.sh script by changing the directory paths, to make sure I didn't miss anything.

I cleaned up everything yet again, and installed yet again. Same problem as before. Trying to load any module gives the same error.

 require 'nn'

 require 'nn'

[string " require 'nn'"]:1: loop or previous error loading module 'nn'

I have also tried using the torch-distro installation you provided. Still the same error.

I have a very similar error.

th> require 'nn'

/usr/local/share/lua/5.1/nn/init.lua:1: loop or previous error loading module 'torch'

stack traceback:

[C]: in function 'require'

/usr/local/share/lua/5.1/nn/init.lua:1: in main chunk

[C]: in function 'f'

[string "local f = function() return require 'nn' end ..."]:1: in main chunk

[C]: in function 'xpcall'

/usr/local/share/lua/5.1/trepl/init.lua:553: in function </usr/local/share/lua/5.1/trepl/init.lua:489>

I am on osx 10.9.3.

Any help appreciated. I have been trying to go through the tutorial, but I cannot import any package.

Thanks in advance.

Cyril

[Cyril b-r]

And I get the same error with the locally installed torch-distro.

[Cyril b-r]

My g++ compiler was buggy, and the install script did not install everything properly I suppose.

Re-installing/updating xcode + cleaning torch with the script fixed my issue.

[Ozan Arkan Can]

I got same error on Ubuntu 14.04

I fixed this today in trunk. Please reinstall and check.

It works. Thanks.
