RANSAC CUDA code error: invalid device symbol

[BQLiu2021]

The RANSAC CUDA code cannot launch on my GPU(TITAN Xp).

~/Deep-SfM-Revisited-main/RANSAC_FiveP$ python test.py Ground-truth E matrix tensor([[-0.1391, -0.0442, 0.5476], [ 0.1396, -0.0444, -0.1480], [-0.4839, 0.2972, -0.1344]]) Start essential matrix initialisation CUDA Error (/data3/liubq/Deep-SfM-Revisited-main/RANSAC_FiveP/essential_matrix/essential_matrix.cu:145): invalid device symbol Segmentation fault (core dumped)

Setting SET(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS}; --std=c++11; -gencode=arch=compute_61,code=sm_61) in CMakelists.txt and ext_modules=[ CUDAExtension('essential_matrix', sources, extra_compile_args={ 'cxx':['-O2'], 'nvcc':'-gencode', 'arch=compute_61,code=sm_61'} ), # extra_compile_args, extra_link_args ], in setup.py does not help. How to deal with this problem in different devices? Thanks!

By the way, my CUDA version is also 10.1

Hi, could you share the log file when you compile the package?

Considering the case here, could you just modify CMakelists.txt while not change setup.py?

Still doesn't work...... orz
