i have a same error

Same error, Ubuntu 16.04, cuda 9.0

Same problem, further up the compile log I see:

@tastyminerals
Still not working in CUDA 9.1

hzxie on 14 May 2018

Are you sure, because I have CUDA 9.1 installed and working with Torch.
Please provide the error message.

tastyminerals on 16 May 2018

@tastyminerals
I've solved this problem.
I used sudo but export is for the current user.

hzxie on 16 May 2018

@tastyminerals
Just use su and it will solve this problem.

hzxie on 16 May 2018

Met the same question,not work by using method above,any other suggestions?

Harry-675 on 22 Jun 2018

This worked for me:

sudo su
export TORCH_NVCC_FLAGS="-D__CUDA_NO_HALF_OPERATORS__"
bash install-deps
yes | bash ./install.sh

The solution given by @adam-dziedzic worked for me! Thanks!

The solution given by @adam-dziedzic worked for me too! Only a few modifications on ~/torch/install/bin/torch-activate and chown for some files in ~/torch/install/bin. Thanks!

mherrera-dsci on 23 Sep 2018

Be careful with the solution that @adam-dziedzic provided because installing torch under sudo su changes the installation path of torch which may break your luarocks package manager.

@mherrera-dsci Did the chown you did on ~/torch/install/bin and the other modifications you did allow you to use luarocks from a non super-user? I'm finding that I can only use luarocks in super-user mode.

The solution given by @adam-dziedzic worked for me too! Only a few modifications on ~/torch/install/bin/torch-activate and chown for some files in ~/torch/install/bin. Thanks!

Hi, could you please tell me how to modify? I found that after using sudo su to install torch, the torch can only be used in su.

ShijianXu on 24 Dec 2018

This worked for me:

sudo su
export TORCH_NVCC_FLAGS="-D__CUDA_NO_HALF_OPERATORS__"
bash install-deps
yes | bash ./install.sh

year, this is also worked for me! I solved this problem.

This worked for me:

sudo su
export TORCH_NVCC_FLAGS="-D__CUDA_NO_HALF_OPERATORS__"
bash install-deps
yes | bash ./install.sh

thanks, worked for me

dinhphuong98 on 18 Oct 2019

@adam-dziedzic 's solution works for me, however I don't use the command sudo su. Many thxs!

Yes, mine is broken. How to solve this?
