nvcc fatal : Unsupported gpu architecture 'compute_20' #1918
Comments
|
Are you using CUDA 9.0?
Fermi (aka 2.x) was deprecated in CUDA 8.0 and removed in CUDA 9.0. Kaldi
hasn't been fully updated for CUDA 9.0 quite yet. It should be a simple
fix, though.

Sorry, would you provide more information how can I fix it in detail? Thanks so much. |

Oh, sorry, there is definitely an issue in master right now.
First get the latest master branch. I assume you know how to do this.
Delete "-gencode arch=compute_20,code=sm_20 "
in this line:
https://github.com/kaldi-asr/kaldi/blob/master/src/configure#L431
The ./configure && make depend && make && make test
Let us know if that fixes it. I could check this myself, but I've been
crunched for time lately and don't want to get CUDA 9 onto one of my dev
machines right this instant.

If the problem persists after removing the |
|
U can remove the line -gencode arch=compute_20,code=sm_20 and -gencode arch=compute_20,code=sm_21 in Makefile.config. |
|
I just pushed a change to remove compute_20 from the nvcc flags. |
|
Deleting "-gencode arch=compute_20,code=sm_20 " doesn't work if you're using cmake to compile, as Makefile.config is not used (it's only used if you compile using make). The solution is to edit caffe/Cuda.cmake. On line 9 simply delete 20 21(20) from the list of GPU architectures. |
