@vinjn 当我运行时，出现如下错误，请问怎样解决啊？ feature_visualization

vinjn commented 4 years ago

Does the following cmd line work?

feature-viz.exe -cfg=cfg\yolov3.cfg -weights=yolov3.weights data\dog.jpg

1274085042 commented 4 years ago

以下cmd行有效吗？

feature-viz.exe -cfg = cfg \ yolov3.cfg -weights = yolov3.weights data \ dog.jpg

feature-viz-error

还是一样的，请问为什么出现这样的错误呢

看着像是 opencv 的问题了，它把 jpg 当成视频来解码，但是解码出错了。 你换成摄像头、视频试试

feature-viz.exe -cfg=cfg\yolov3.cfg -weights=yolov3.weights 0 feature-viz.exe -cfg=cfg\yolov3.cfg -weights=yolov3.weights video.mp4

重装opencv试试，使用 darknet.exe 会报错么
