Torch7 Installation Failed

Hi Everyone,

I am installing Torch regarding the DIGITS/BuildTorch.md, However, I encountered building error which is:

[ 15%] Building NVCC (Device) object lib/THC/CMakeFiles/THC.dir/THC_generated_THCTensorMathReduce.cu.o
1 error detected in the compilation of "/tmp/tmpxft_000020e7_00000000-6_THCTensorMathPairwise.cpp1.ii".

I googled the problem and found a suggested solution(this problem was reported as a bug and fixed) which is:

./clean.sh
export TORCH_NVCC_FLAGS="-D__CUDA_NO_HALF_OPERATORS__"
./install.sh

It did not help. there is also another recommendation which is installing CUDA-8 instead of CUDA-9.1. I do not want to downgrade the version of CUDA. Is there any other suggestion to fix this problem?

Kind regards, Ender.

Problem solved. Just uninstall the torch:

rm -rf ~/torch

and follow the official torch instructions: http://torch.ch/docs/getting-started.html
