Does caffe support CUDA9.0 version? Since i want to download CUDA8.0 version, however 8.0's download link is out of date.

Issue summary

Steps to reproduce

If you are having difficulty building Caffe or training a model, please ask the caffe-users mailing list. If you are reporting a build error that seems to be due to a bug in Caffe, please attach your build configuration (either Makefile.config or CMakeCache.txt) and the output of the make (or cmake) command.

Your system configuration

Operating system:
Compiler:
CUDA version (if applicable):
CUDNN version (if applicable):
BLAS:
Python or MATLAB version (for pycaffe and matcaffe respectively):

meet some error when compiling with 9.0 on ubuntu
Unsupported gpu architecture 'compute_20'

[autocyz]

@zuo1188 I also meet the same error "Unsupported gpu architecture 'compute_20'" with cuda9.0, do you resolve it ?

[ShaggO]

@autocyz @zuo1188 I believe you can resolve that issue by changing the configuration in Makefile.config. Simply remove "-gencode arch=compute_20,code=sm_20"

[erikaemma]

@ShaggO It will fail in 'make runtest'

Also looking for CUDA 9 support

[Noiredd]

Caffe is compatible with CUDA 9. Look at the comments added in #6079.

Removed compute_20, facing issue with protobuf. Any leads??

@kalyc I doubt this is related to CUDA 9.0 compatibility. Have you installed protobuf-devel or libgflags-dev libgoogle-glog-dev.

Though Caffe Installation Guides says it's only required for Ubuntu 14.04, but I find that it's also necessary for 16.04
