Build error in TensorMath.lua: "attempt to call method 'registerDefaultArgument' (a nil value)"

[alimuldal]

Hi there,

I'm currently struggling to build cutorch on Ubuntu 14.04 (CUDA 6.5, GCC-4.8.2). I'm hitting a build error in TensorMath.lua:

/home/alistair/torch/install/bin/luajit: /tmp/luarocks_cutorch-scm-1-9849/cutorch/TensorMath.lua:184: attempt to call method 'registerDefaultArgument' (a nil value)
stack traceback:
        /tmp/luarocks_cutorch-scm-1-9849/cutorch/TensorMath.lua:184: in main chunk

make[2]: *** [TensorMath.c] Error 1
make[1]: *** [CMakeFiles/cutorch.dir/all] Error 2
make: *** [all] Error 2

Error: Build error: Failed building.

The full build log is below. Any thoughts on what might cause this?

Cheers,
Alistair

The easiest way to fix this is to run install.sh script from distro again

[alimuldal]

OK, I just tried that and I'm getting the same build error in the output of the install script. What do you think is the root cause of this?

[szagoruyko]

ah, distro doesn't update packages any more, you have to update the distro folder with git pull origin master and then ./install.sh

[alimuldal]

Still no joy - I hit the same build error in cutorch when running install.sh even after a git pull origin master && git reset --hard HEAD

[soumith]

the issue here is an outdated cwrap package.
registerDefaultArgument was introduced by @dominikgrewe in this commit: torch/cwrap@48bbfee

However, you seem to have an outdated cwrap. If you installed fresh from distro, cwrap will install fresh and updated.

[alimuldal]

I just removed ~/torch and reinstalled torch and its dependencies from scratch, following the instructions here. I see the same build error in the output of install.sh, and when I subsequently try to install cutorch using luarocks install cutorch.

I've also tried manually pulling the latest version of cwrap from the Github repository (torch/cwrap@6b7bb2a), then calling luarocks install rocks/cwrap-scm-1.rockspec. This seems to work fine, but when I subsequently try building cutorch it still fails with the same build error (I've also tried manually pulling the latest cutorch source and manually installing it in the same way, and I get the same error).

I'm very new to Lua, so perhaps I'm missing something obvious about how Lua package management works?

[dominikgrewe]

Do you maybe have two versions of cwrap installed (one local and one global)?
You can list all installed packages by calling "luarocks list". If you see cwrap twice, try removing both installation and then installing it again.

[alimuldal]

@dominikgrewe That doesn't seem to be the case:

~$ luarocks list

[alimuldal]

OK, finally figured it out. I did, in fact, have another global version of cwrap installed in /usr/local/share/lua/5.1/cwrap/. Deleting it fixed the build error, even though the global version of cwrap was not listed in the output of luarocks list.

Thanks for your patience!
