Hi,

Can you update the RTMW-X ONNX to the latest version?
https://github.com/open-mmlab/mmpose/blob/main/configs/wholebody_2d_keypoint/rtmpose/cocktail14/rtmw_cocktail14.md
rtmw-x_simcc-cocktail14_pt-ucoco_270e-384x288-f840f204_20231122.pth
rtmw-x_simcc-cocktail14_pt-ucoco_270e-256x192-13a2546d_20231208.pth

Thanks,

-Scott
