input images can work very well by "--input", but web camera can`t work by “--webcam ”

i run python demo/demo.py --config-file configs/transfiner/mask_rcnn_R_50_FPN_1x.yaml --webcam --opts MODEL.WEIGHTS ./pretrained_model/output_1x_transfiner_r50.pth , but many errors occurred.

can you run demo with "--webcam" normally?
