operating speed of Raspberry Pi

[2684160504]

Hello, I am on 1660TiGPU in ubuntu16.04, yolofastest speed is 30 frames, and about 1 frame on Raspberry Pi. Is this normal?Looking forward to your reply, thank you.

I have tried yolo-fastest at RaspberryPi 4 (8GB) with opencv 4.4，and the result is about 7~8 fps.

Hi @liuyijian can you please provide some information on what is the input resolution you had your model tested for in raspberry pi?

[liuyijian]

Hi @sudo-install-MW My input resolution to the model is 320*320, which is the default setting in yolo-fastest.cfg. I use function cv2.dnn.blobFromImage(...) to transform the original frame (1280*720) that capture from the camera, to 320*320 as model input. As I am not sure if I can change the default width and height paremeter in yolo-fastest.cfg, I make temporary practice like this. Hope to learn some practical trick from you.

兄弟，树莓派4上面执行ncnn_sample里面的指令，一直报错benchmark.h文件找不到，有遇到过吗

@jereter ncnn_sample里的前面几个include需要的文件在Tencent/NCNN仓库的src目录里，具体地址如下： https://github.com/Tencent/ncnn/tree/b93775a27273618501a15a235355738cda102a38/src
