The error of the misaligned address appears on testing a very small SFM problem.
ChenMa2017 opened this issue · comments
I test the MegBA using a very small SFM problem. It has two cameras, 600 3D points, and 1200 observations.
The SFM problem has the format of Bundle Adjustment in the Large. BAL
The BAL_Double aborts after the error of " cudaErrorMisalignedAddress: misaligned address".
The input command is
" ./BAL_Double --path ~/Data/problem-2-599-pre.txt --world_size 1 --max_iter 10 --solver_tol 1e-1 --solver_refuse_ratio 1 --solver_max_iter 10 --tau 1e4 --epsilon1 1 --epsilon2 1e-10" .
The whole output on the screen is
"solving /Data/problem-2-599-pre.txt, world_size: 1, max iter: 10, solver_tol: 0.1, solver_refuse_ratio: 1, solver_max_iter: 10, tau: 10000, epsilon1: 1, epsilon2: 1e-10

terminate called after throwing an instance of 'thrust::system::system_error'
what(): after reduction step 1: cudaErrorMisalignedAddress: misaligned address
Aborted".
But when I remove one 3D point and its 2 observations, the MegBA works.
The edited SFM problem has two cameras, 599 3D points, and 1198 observations.

Could you give any suggestions about the error?
This happens on my laptop's RTX 2080. On the RTX 3090, everything goes well.
这个我测试了，好像是只要相机帧数是奇数就会报错，偶数就没问题
