After 100 Epoch Total Loss Is Still Very High

[rhiver]

The loss is about 2000-3000, the loss doesn't change much from epoch 3 to epoch 100. Anything wrong with it？

I've observed a decreasing loss for around 100 epochs but, indeed the value remains too high. I like the idea used in HRNet-Bottom-Up-Pose-Estimation where they apply clever masks before calculating the loss. The masks contain 1s at the joints location, 0s at the crowd or 0-keypoints segmentations, remaining pixels contain background color.
