Test failed: could not load cltorch, skipping

[sorrge]

Hi,

I've installed cltorch as described here: https://github.com/hughperkins/cltorch During "luarocks make rocks/cltorch-scm-1.rockspec", I had a lot of warnings but no error message. The last line says "cltorch scm-1 is now built and installed in (license: BSD)"

However, when I run "th -l cltorch -e 'cltorch.test()'" afterwards, it says: could not load cltorch, skipping [string "cltorch.test()"]:1: attempt to index global 'cltorch' (a nil value)

have the same problem on a new macbook

Hi, if you install the latest version of 'new-easycl' branch, and install that, how well does that work? ie:

git clone --recursive https://github.com/hughperkins/cltorch.git -b new-easycl
cd cltorch
luarocks make rocks/cltorch-scm-1.rockspec
th -l cltorch -e 'a = torch.ClTensor({3,5,2}); print(a); print(a+2)"

Tried it (without uninstalling the original cltorch, should I?). The installation seemed to be successful. I have the same result: "could not load cltorch, skipping" and then "attempt to call field 'ClTensor' (a nil value)". I am also on a Mac, BTW. Is there some kind of debug mode that will show more information than just "could not load"?

[hughperkins]

Ah, fair enough. Out of ideas for now. If nothing else comes up, I might need remote access to one of your macs ideally, eg using TeamViewer or similar (TeamViewer lets you see what I'm doing whilst I'm doing it).

BTW. Is there some kind of debug mode that will show more information than just "could not load"?

You can use luajit instead of th. If that's still not sufficiently detailed, need to use gdb to run luajit.

Hi. I think I'd like to see two things:

• full output of running cd ~/torch; ./install.sh
• full output of the cltorch installation

No need to uninstall either of these first. I just want to see what things are failing in these. eg, I suspect maybe gfortran or similar might be missing.

adding

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:~/torch/install/lib

to .bash_profile solved the problem

[sorrge]

Thanks! That works. An update to the installation instructions would be nice.

[hughperkins]

Hmmm, is that not already part of torch-activate? However, I shall update the instructions for cltorch to mention this point.

Edit: by the way, glad it works. Thank-you very much Sergey for solving this :-)

Seems like this can be closed, right?
