About deformation Gaussians suddenly flew off #34

Closed guanjunwu closed 8 months ago

guanjunwu commented 8 months ago

Hello, I'm wondering if you've encountered a similar issue during optimization: Initially, the entire scene was converging normally, but midway through the training, some dynamic points suddenly flew off to a far distance, leading to a seemingly inexplicable failure in the training process.

I guess the problem mainly occurred from cuda?

I know this problem. Just reduce the learning rate of the deformation field.

感谢老哥，虽然我也不知道为什么。。。
