RuntimeError: mat1 and mat2 shapes cannot be multiplied (1x207 and 486x31425)

[Wonters]

Hi,

I installed mmhuman3d, and try to use it but a stack appear when i launch the demo: python demo/estimate_smpl.py configs/hmr/resnet50_hmr_pw3d.py data/checkpoints/resnet50_hmr_pw3d.pth --single_person_demo --det_config demo/mmdetection_cfg/faster_rcnn_r50_fpn_coco.py --det_checkpoint https://download.openmmlab.com/mmdetection/v2.0/faster_rcnn/faster_rcnn_r50_fpn_1x_coco/faster_rcnn_r50_fpn_1x_coco_20200130-047c8118.pth --input_path demo/resources/single_person_demo.mp4 --show_path vis_results/single_person_demo.mp4 --output demo_result --smooth_type savgol --speed_up_type deciwatch --draw_bbox

first:
The model and loaded state dict do not match exactly

second:

Do you know how to fix this error ?

Same error, were you able to fix it? it seems like 207 (23 * 3 * 3) is the shape of the joint dims but I am not sure what 486 is - 486 comes from the smpl pkl file under the pose dir parameter, and shape dir parameter, but there is no place in the documentastion to know what these things mean, it would be very helpful if you can let me know if you found a solution (since this seems like a 2 year old issue), thank you so much for your time!
