Hi, I replaced the feature match part with lightglue. I ran multiple experiments on the same dataset, and the results of lightglue were consistent, but the final results of OpenMVG were inconsistent (I have already disabled OpenMP). I wonder waht is the reason. Thanks.

I already configured my OMP config to use just one thread but the result is still not deterministic. Not sure if this is the solution you mentioned.

Do note that ceres is not deterministic if using it with threads too. Did you set one thread there too?
