TypeError: __init__() got an unexpected keyword argument 'legacy'

运行程序时出现以下错误提示，如何解决？
$python tools\demo.py video -n yolox-x -c ..\weights\yolox\yolox_x.pth --path MOT16-03.mp4 --conf 0.25 --nms 0.4 --tsize 640 --save_result --device gpu

TypeError: init() got an unexpected keyword argument 'legacy'

Start in tools/demo.py at the ValTransform(legacy=legacy) call shown in the traceback, then inspect the ValTransform constructor it imports. Re-run the supplied video command after making the compatibility change; done means the unexpected-keyword error is gone and video processing starts.
