Trouble installing torch-scatter

[Yannick-S]

I am having trouble installing torch-scatter on my local machine. I have a old cpu (9 years or so) and a 970gpu.
I installed torch via
pip3 install torch torchvision
and

python -c "import torch; print(torch.version)"

1.0.1.post2
python -c "import torch; print(torch.cuda.is_available())"

True

nvcc --version

So good so far, i hope. After adding the PATH and CPATH as suggested in the 'install' documentation, I do
$ git clone https://github.com/rusty1s/pytorch_scatter
$ cd pytorch_scatter
$ python setup.py install

with the following output

Any suggestsions?

I seperate this into two comments becasue its two approaches:
I also tried simply installing via pip install torch-scatter. This gives no errors, but doing

python -c "import torch; import torch_scatter"

Traceback (most recent call last):

[Yannick-S]

I tried several other approaches, but i believe the main issue lies in the
/usr/bin/nvcc ... call. Any ideas what could be causing this and how to get rid of the problem?

[rusty1s]

Have you tried to google the error message? (e.g. NVIDIA/nccl#29)

It seems solvable by adding the following CXX flags:
-D_MWAITXINTRIN_H_INCLUDED
-D_FORCE_INLINES
-D__STRICT_ANSI__

[Yannick-S]

Yes i looked at that. But i have
nvcc --version:
Cuda compilation tools, release 7.5, V7.5.17
Is that an issue. I am upgrading my whole cuda world right now to see what happens next.
If this doesn't help i will look more int ot he CXX flags

[rusty1s]

I've never tested it with CUDA 7.5. Hopefully CUDA 8 might fix this issue.

[Yannick-S]

success with cuda 9.2! Thanks anyways!
