[sdlmw]

i have a same error

[zhouqilin1993]

Same error, Ubuntu 16.04, cuda 9.0

[soveraign]

Same problem, further up the compile log I see:

Ubuntu 16.04, cuda 9.0

[tastyminerals]

This has been reported and fixed in torch/cutorch#797
Set env var: export TORCH_NVCC_FLAGS="-D__CUDA_NO_HALF_OPERATORS__"

[hzxie]

@tastyminerals
Still not working in CUDA 9.1

[tastyminerals]

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

[hzxie]

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

[hzxie]

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

[Harry-675]

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

[adam-dziedzic]

This worked for me:

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

[Spandan-Madan]

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

[mherrera-dsci]

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!

[btomtom5]

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.

[frahman5]

@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.

[ShijianXu]

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.

[wu-yy]

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.

[dinhphuong98]

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

[BurkeyLai]

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

[Ujang24]

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.

Yes, mine is broken. How to solve this?

[Lilidamowang]

Thanks!!! it works for me!!
