Hello.
When I am running the webcam demo with "python run_video.py -c configs/mpii/config_blazepose_mpii_pushup_heatmap_bce_regress_huber.json -m blazepose_pushup_v1.h5 -v webcam --confidence 0.3", an error occurs:

raise ValueError('The model cannot be compiled '
ValueError: The model cannot be compiled because it has no loss to optimize.
It seems that the model needs to be trained before running with webcam. And the error appears when training begins.
Are there any solutions for it? I am looking forward to your reply. Thans you so much.
