Deterministic problem

[kefusong]

When I use this pointnet2_ops_lib for pointnet2, I found out the atomicAdd() function in the .cu file is not fixed in order when called, resulting in a numerical error in the sum of floating points as a result of gradient calculations. And set_seed() in python is useless.
I found that your amazing network is based on this package, and how do you deal with this non-determinism?
If determinism is not guaranteed, ablation experiments can be cumbersome.
Thank you!
