《------正文------》
前言
本文主要介绍如何打印并且查看YOLOv8网络模型的网络结构配置信息、每一层结构详细信息、以及参数量、计算量等模型相关信息。 该方法同样适用于改进后的模型网络结构信息及相关参数查看。可用于不同模型进行参数量、计算量等对比使用。
查看配置文件结构信息
在每次进行YOLOv8模型训练前，都会打印相应的模型结构信息，如上图。但是如何自己能够直接打印出上述网络结构配置信息呢？，博主通过查看源码发现，信息是在源码DetectionModel类中，打印出来的。因此我们直接使用该类，传入我们自己的模型配置文件，运行该类即可，代码如下：
class DetectionModel(BaseModel):"""YOLOv8 detection model."""def __init__(self, cfg="yolov8n.yaml", ch=3, nc=None, verbose=True): # model, input channels, number of classes"""Initialize the YOLOv8 detection model with the given config and parameters."""super().__init__()self.yaml = cfg if isinstance(cfg, dict) else yaml_model_load(cfg) # cfg dict# Define modelch = self.yaml["ch"] = self.yaml.get("ch", ch) # input channelsif nc and nc != self.yaml["nc"]:LOGGER.info(f"Overriding model.yaml nc={self.yaml['nc']} with nc={nc}")self.yaml["nc"] = nc # override YAML valueself.model, self.save = parse_model(deepcopy(self.yaml), ch=ch, verbose=verbose) # model, savelistself.names = {i: f"{i}" for i in range(self.yaml["nc"])} # default names dictself.inplace = self.yaml.get("inplace", True)# Build stridesm = self.model[-1] # Detect()if isinstance(m, Detect): # includes all Detect subclasses like Segment, Pose, OBB, WorldDetects = 256 # 2x min stridem.inplace = self.inplaceforward = lambda x: self.forward(x)[0] if isinstance(m, (Segment, Pose, OBB)) else self.forward(x)m.stride = torch.tensor([s / x.shape[-2] for x in forward(torch.zeros(1, ch, s, s))]) # forwardself.stride = m.stridem.bias_init() # only run onceelse:self.stride = torch.Tensor([32]) # default stride for i.e. RTDETR# Init weights, biasesinitialize_weights(self)if verbose:self.info()LOGGER.info("")# 模型网络结构配置文件路径
yaml_path = 'ultralytics/cfg/models/v8/yolov8n.yaml'
# 改进的模型结构路径
# yaml_path = 'ultralytics/cfg/models/v8/yolov8n-CBAM.yaml'
# 传入模型网络结构配置文件cfg, nc为模型检测类别数
DetectionModel(cfg=yaml_path,nc=5)
运行代码后，打印结果如下：
打印结果说明：
可以看到模型配置文件一共有23行，params为每一层的参数量大小，module为每一层的结构名称，arguments为每一层结构需要传入的参数。最后一行summary为总的信息参数，模型一共有225层，参参数量（parameters）为：3157200，计算量GFLOPs为：8.9.
查看详细的网络结构
上面只是打印出了网络配置文件每一层相关的信息，如果我们想看更加细致的每一步信息，可以直接使用model.info()来进行查看，代码如下：
加载训练好的模型或者网络结构配置文件
from ultralytics import YOLO
# 加载训练好的模型或者网络结构配置文件
model = YOLO('best.pt')
# model = YOLO('ultralytics/cfg/models/v8/yolov8n.yaml')
打印模型参数信息：
# 打印模型参数信息
print(model.info())
结果如下：
打印模型每一层结构信息：
在上面代码中加入detailed参数即可。
print(model.info(detailed=True))
打印信息如下：
