nvcc fatal : Value 'sm_20' is not defined for option 'gpu-architecture'

[Tom-Y-Liu]

When I try to generate a python wrapper, it returns error information as follow: nvcc fatal : Value 'sm_20' is not defined for option 'gpu-architecture'

My cuda version is 11.0, and using a GTX 1050ti gpu.

Any idea how to solve this?

Thanks!

Hi there,

This looks like an nvcc issue; the options are listed on the docs: https://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html#virtual-architecture-feature-list

(nvcc has changed the available keywords for that option)

Hi Kyle, Em... I am new to nvcc, how can I fix this issue? I do find "'nvcc': ['-arch=sm_20', '--ptxas-options=-v'" in the 'pyjacob_cuda_setup.py.in' file. But, no matter how I adjust the arch value, it still reports 'sm_20' error.

Update: I changed all the 'sm_20' in the libgen.py file and in the 'pyjacob_cuda_setup.py.in' into 'sm_61'. The error fixed.

But new error information shows up as follows:

cl : Command line warning D9002 : ignoring unknown option '-fPIC' fatal error C1083: Cannot open include file: 'helper_cuda.h': No such file or directory

Final Update: Using Linux instead of Windows, everything solved.
