🍅🍅🍅YOLOv5-Lite: lighter, faster and easier to deploy. Evolved from yolov5 and the size of model is only 1.7M (int8) and 3.3M (fp16). It can reach 10+ FPS on the Raspberry Pi 4B when the input size is 320×320~

Overview

YOLOv5-Lite：lighter, faster and easier to deploy

Perform a series of ablation experiments on yolov5 to make it lighter (smaller Flops, lower memory, and fewer parameters) and faster (add shuffle channel, yolov5 head for channel reduce. It can infer at least 10+ FPS On the Raspberry Pi 4B when input the frame with 320×320) and is easier to deploy (removing the Focus layer and four slice operations, reducing the model quantization accuracy to an acceptable range).

你好，大佬，就是我想问一下如果使用trt或tensorrt加速能够用c++的api吗，因为目前我的项目其他部分是用的c++，然后用tensorrt加速yolov5用的是c++，主要是我看您这个把pplcnet和yolov5s结合的工作在速度上有很大提升，我就是想用openvino的c++的api来推理可以吗？

MNN performance much less than NCNN

Hi, has anybody met the problem that MNN has less performance than NCNN？ Like the confidence and mAP? I printed out the outputs of NCNN and MNN in terms of the same image, but their outputs differ a lot. The confidences of MNN are almost all lower than NCNN, and bboxs are worse as well. Another question is that my input size of an image is 320 * 240, but the model input size is 320 * 256. Is that reasonable?

shufflenetv2预训练的模型的问题

请问您有用shufflenetv2的预训练模型训练吗？我要用pytorch官网的'shufflenetv2_x1.0' 模型的时候出现层的shape对应不上的问题：左边是官方的，右边是你的 10 : stage2.0.branch1.2.weight torch.Size([58, 24, 1, 1]) __ model.1.branch1.1.running_var torch.Size([24]) 11 : stage2.0.branch1.3.weight torch.Size([58]) __ model.1.branch1.1.num_batches_tracked torch.Size([]) 12 : stage2.0.branch1.3.bias torch.Size([58]) __ model.1.branch1.2.weight torch.Size([60, 24, 1, 1]

你的模型会出现多出一层‘model.1.branch1.1.num_batches_tracked’ 而且shape是[ ]空的，网上说这是新版pytorch的问题但是主要问题是左边stage2.0.branch1.2 ([58, 24, 1, 1]) 和右边你的branch1.2.weight torch.Size([60, 24, 1, 1] 开始出现shape不匹配，接下去陆陆续续都开始shape不一样了

是您搭建网络出错了吗？

v5Lite-g模型训练时map很低。

我正在进行该项目思路相同的工作，我认为将repvgg嵌入到yolov5中是一种很好的想法，根据v5Lite-g.yaml提供的模型结构，我使用nn.model重新构建了该结构，并将提供的权重转换到我重构的模型结构内，在我的测试中两个模型具有完全相同的检测结果，姑且我认为以上的工作，我是正确的。但是当使用我自己重构的结构来训练模型时，我发现得到的map(Terminal截图)会比该项目使用lite-g训练的map(日志截图)会低很多，即使我使用了完全相同的训练配置。 Yolov5-Lite项目基于v5 5.0版本开发，请问，相较u版的代码，该项目是否在lite-g模型测试时添加了其他额外的操作，或者额外的方法呢？

unexpected result

Hello

Sorry if this is more a question that an issue, i'm not sure if i'm doing something wrong.

I trained a new model, using the v5lite-s weight with "person" class using coco + voc dataset, the 1k background images as negative samples and to have an input of 320. I did not change any hyperparameter and using ncnn framework

I get: mAP 05:0.95 of 0.498 mAP 05 of 0.795 Precision 0.84 Recall 0.68

I was expecting to have a better result than the provided model trained on all coco classes... but as you can see there is at least two persons not detected.

Maybe is a problem on the model conversion?

Thanks

another question,is that possible for me to load the model by hub or something else?

文档中我看4b可以运行10帧多？说是80ms左右，实际用cm4跑只有2帧，问题在哪呀

是用的v5lite-s模型 img-size也改成了320 请问还有哪里没设置对吗，为何帧数相差如此之大
