Tutorial for using Torch7 on Amazon EC2 GPUs
Raw
Tutorial.md

There used to be a tutorial here for using Torch7 on EC2, but it's now outdated. It is best to use an EC2 image that already has Torch7 and CUDA stuff preinstalled.

Hi, I followed the instructions on this page and got the following error:

/usr/local/bin/luajit: unable to initialize cublas
stack traceback:

[C]: in function 'require'
/usr/local/share/lua/5.1/cutorch/init.lua:2: in main chunk

/usr/local/lib/luarocks/rocks/trepl/scm-1/bin/th:129: in main chunk

Update:
The problem was in the gpu drivers provided by Amazon.

Thanks for the tutorial!

Unfortunately it doesn't seem to be working for me:

$ th -l cutorch -e "cutorch.test()"
could not load cutorch, skipping
[string "cutorch.test()"]:1: attempt to index global 'cutorch' (a nil value)
