Question about LM loss

[CVHW]

Hello, thanks for releasing the code. I really appreciate your work.

I have a question: When I train the code, the LM loss descends gradually at the beginning. However, it ascends gradually after the 50th epoch. Have you ever meet this problem? I look forward to your reply.

Sorry for the late reply.
It is possible. As we only consider the synthetic mask loss as an auxiliary loss, our ultimate goal is the keypoint loss.
After 50 epochs, the model needs to focus more on the keypoint.
