i was using windows 10, VS community 2015, and CUDA 8.0. this problem appeared to me and solved by: right click on "currennt_lib" project -> properties -> CUDA C/C++ ->Code generation -> then i changed it to compute_20,sm_21
Hi all, i have the same problem, did anyone find a solution for this error?
