CUDA fails after installation

[sergei-sh]

Installed torch, cuda, cunn.

test.py

import lutorpy as lua
lua.require('cunn')

Output:

THCudaCheck FAIL file=/home/serj/torch/extra/cutorch/lib/THC/THCGeneral.c line=66 error=30 : unknown error

Tests fail the same way:

(venv) serj@venus ~/work/beautytorch/beauty.torch $ luajit -l cunn -e 'cunn.test()'

Related code:

{
  if (!state->cudaDeviceAllocator) {
    state->cudaDeviceAllocator = &defaultDeviceAllocator;
  }
  if (!state->cudaHostAllocator) {
    state->cudaHostAllocator = &THCudaHostAllocator;
  }
  if (!state->cudaUVAAllocator) {
    state->cudaUVAAllocator = &THCUVAAllocator;
  }

  int numDevices = 0;
  THCudaCheck(cudaGetDeviceCount(&numDevices)); // FAILS HERE!!!

Maybe the problem relates to the fact that my GPU is not NVidia, but lua.require("cunn") is needed as a part of 3-rd party project which I'm trying to use

You should have Nvidia GPU if you work with any deep learning framework these days. Yes, you must have Nvidia GPU to run torch on GPU.
Consider closing the issue please.
