cutorch error

Hey dude, I've tried to compile but I'm having some difficulties around the cutorch dependencies.

Ubuntu 16.04, opencv 3.1 everything tested and working.
I'm using Cuda 8.0 and torch 7 with cutorch installed as well.
I have a feeling it's a path error but can't for the life of me find out where the problem is.

Thanks a mill
Evan

Hey,
I wrote my additions to this library when Torch 4 was out -- I don't know if "THCudaBlas_gemm" is still defined in the cutorch repo.
It should be in this file: https://github.com/torch/cutorch/blob/master/lib/THC/THCBlas.cu
A similar issue appeared here with the same function call:
https://groups.google.com/forum/#!topic/torch7/jIyveGldcE0
Still debating the workaround to this. I'll update the library ASAP.
Best,
Matt

Just for anyone else, if you want this to work for you
go into your torch directory (if cloned with git)
enter the commands below:

git reset --hard 722262711ce35a73c9a2847c005a65d887e51f1e
./clean.sh
./install.sh

This version of torch works fine. Tested on Ubuntu 16.04
