Failing to load requirements

After following the installation instructions on Ubuntu 15.04, when I try to run, I get the following error:

$ th waifu2x.lua
/usr/local/bin/luajit: /usr/local/share/lua/5.1/trepl/init.lua:363: cuda runtime error (30) : unknown error at /tmp/luarocks_cutorch-scm-1-9445/cutorch/lib/THC/THCGeneral.c:16

I tried the solution for the similar-looking problem #3

$ echo $LD_LIBRARY_PATH
/usr/local/lib

But still get the same error

It's seems to be CUDA installation issue.
Maybe CUDA is not installed correctly.

It looks like it is...

$ nvcc --version                  
nvcc: NVIDIA (R) Cuda compiler driver

Cuda compilation tools, release 6.5, V6.5.12

I'll try reinstalling using 6.5.14 instead, see if that works.

try

# When CUDA install path=/usr/local/cuda-7.0/
export PATH=/usr/local/cuda-7.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-7.0/lib64:$LD_LIBRARY_PATH
export CUDA_BIN_PATH=/usr/local/cuda-7.0/bin

Well, you were right about it being a cuda issue - it works if I install cuda 7.5 from the deb package, but not if I build it locally. Thanks!

[nagadomi]

That was good.
