板子上mipi_camera.py例程中修改模型文件从原本的focs_512*512_nv12.bin改为yolov5_672*672_nv12.bin
运行例程会调用摄像头一瞬间后闪退，报错
Traceback (most recent call last):
File"./mipi_camera.py", line 347, in
img = np.frombuffer(img, dtype=np.uint8)
TypeError: a bytes-like object is required,not ‘NoneType’
[INFO]: offload model “yolov5_672*672_nv12.bin” Successfully.
希望有好心人指点我一下，这对我很重要，谢谢
