th -l cltorch cannot load libcltorch.so but luajit -l cltorch works

Jovp commented 8 years ago

Hi,

First I must say that I am really new to torch, lua etc. I am currently trying to install and use cltorch. Apprently the installation went right, but as I am trying to use cltorch with th it does not work and it raises "cannot load libcltorch.so" such as mentioned in : https://github.com/hughperkins/cltorch/issues/5 and https://github.com/hughperkins/cltorch/issues/24 The thing is I am using the mac os Shell (I am on OSX El Capitan) and so the solutions proposed do not seem to be linked to my issue. In another thread I saw the "luajit -l cltorch" command come out and tried it. It seems to start another instance of torch than "th" and wen I do th> c = torch.ClTensor{7,4,5} it seems to work well as I get : "Using Apple , OpenCL platform: Apple Using OpenCL device: Iris"

Do you have any idea on how I can make it work ? Thanks

Did you try removing the first line of the th script, as per https://github.com/hughperkins/cltorch/issues/21

Oh, Thank you very much, I feel so stupid right now, didn't see the post...

Ah, cool :-) We should fix that issue somehow sometime really.

Hey, spend one day on this confused problem. FINALLY I fix it by switch back to bash shell.

th> require 'cltorch'

}

I used zsh before, can't properly load some path. @hughperkins thanks for your explanation. What a mysterious situation!

@hughperkins thank you so much. @tigerneil same as you. I switched to bash. I recommend you to extend bash with bash-it in exchange for zsh.
