i am getting the below error when installing pytorch from the github repository.

i’ll look into it now, the continuous builds pass for some reason. What version of CUDA are you using? What’s the output of the command `nvcc --version`? For a workaround use: ```auto NO_DISTRIBUTED=1 python setup.py install ``` ---

Even I am getting the same error when I run `python setup.py install` `nvcc --version` output : `nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2015 NVIDIA Corporation Built on Tue_Aug_11_14:27:32_CDT_2015 Cuda compilation tools, release 7.5, V7.5.17` PS : `NO_DISTRIBUTED=1 python setup.py install` is working but my question is what is `NO_DISTRIBUTED=1` for? Edit 1: As I previously mentioned, I have installed it via `NO_DISTRIBUTED=1 python setup.py install` but am unable to user `affine_grid` function. ---

I’m experiencing the same problem. Trying to install on a linux machine which I do not have root privilege. NO\_DISTRIBUTED=1 will install but cannot link against the existing cuda. my nvcc --version: nvcc: NVIDIA ® Cuda compiler driver Copyright © 2005-2016 NVIDIA Corporation Built on Sun\_Sep\_\_4\_22:14:01\_CDT\_2016 Cuda compilation tools, release 8.0, V8.0.44 ---

Im having same problem, how we can solve the real problem of gloo library development files? I guess something related to [https://code.ihub.org.cn/projects/123/repositories/159/file\_edit\_page?file\_name=FindGloo.cmake&path=cmake%2FModules%2FFindGloo.cmake&rev=master](https://code.ihub.org.cn/projects/123/repositories/159/file_edit_page?file_name=FindGloo.cmake&path=cmake%2FModules%2FFindGloo.cmake&rev=master) (which I downloaded and can compile on my own) Also I guess this is the library? [GitHub - facebookincubator/gloo: Collective communications library with various primitives for multi-machine training.](https://github.com/facebookincubator/gloo) But the point it is that is inside the third party libs ```auto [22%] Building NVCC (Device) object third_party/gloo/gloo/CMakeFiles/gloo_cuda.dir/gloo_cuda_generated_cuda.cu.o In file included from /home/tyoc213/Documents/github/pytorch/third_party/gloo/gloo/cuda_private.cu:9: In file included from /home/tyoc213/Documents/github/pytorch/torch/include/gloo/cuda_private.h:20: /home/tyoc213/Documents/github/pytorch/torch/include/gloo/cuda.h:24:2: error: "Expected GLOO_USE_CUDA to be defined" #error "Expected GLOO_USE_CUDA to be defined" ^ In file included from /home/tyoc213/Documents/github/pytorch/third_party/gloo/gloo/cuda.cu:9: /home/tyoc213/Documents/github/pytorch/torch/include/gloo/cuda.h:24:2: error: "Expected GLOO_USE_CUDA to be defined" #error "Expected GLOO_USE_CUDA to be defined" ^ 1 error generated.
