4、 当图片的输入 最大size 不是 stride 的整数倍时，打印报警日志
一、安装配置环境
conda create -n yolov5 python=3.7
启动该环境
source activate yolov5pip install -r requirements.txt运行测试demo，即detect.py
这时需要上官网下载对应版本的预训练权重。上图中画线的部分就是当前所用的版本，
点击对应的版本下载即可，然后放到yolo-master即主项目文件夹下即可。
二、Debug记录
1、vars(opt)
2、x
3、ckpt
4、names
list
dict
5、model
前
后
6、dataset
7、dt
8、 m 和 model
model
m 举例
9、y
三、打印日志输出的地方
1、 开始打印参数值
detect: weights=yolov5s.pt, source=data/images, data=data/coco128.yaml, imgsz=[640, 640], conf_thres=0.25, iou_thres=0.45, max_det=1000, device=, view_img=False, save_txt=False, save_conf=False, save_crop=False, nosave=False, classes=None, agnostic_nms=False, augment=False, visualize=False, update=False, project=runs/detect, name=exp, exist_ok=False, line_thickness=3, hide_labels=False, hide_conf=False, half=False, dnn=False, vid_stride=1general.py --- 216
2、若缺少环境，则打印相关警告
general.py --- 362始
3、 打印python版本以及显卡信息
YOLOv5 🚀 2022-10-13 Python-3.7.12 torch-1.12.1+cu102 CUDA:0 (NVIDIA GeForce RTX 2080 Ti, 11019MiB)torch_utils.py --- 139
4、 当图片的输入 最大size 不是 stride 的整数倍时，打印报警日志
check_img_size 函数， general.py ---382
if new_size != imgsz:
LOGGER.warning(f'WARNING ⚠️ --img-size {imgsz} must be multiple of max stride {s}, updating to {new_size}'四、功能接口
0、代码中的 f'{}'
# format 的缩写
s = f'YOLOv5 🚀 111 缩写 torch-{torch.__version__} '
print(s)
>> YOLOv5 🚀 111 缩写 torch-1.12.1+cu102 1、保存结果的路径
detect.py --- 91
save_dir = increment_path(Path(project) / name, exist_ok=exist_ok)其中 project 决定保存的路径
那个exp变化的决定在 general.py 中的 increment_path函数中，即exp2 exp3 等
def increment_path(path, exist_ok=False, sep='', mkdir=False):
# Increment file or directory path, i.e. runs/exp --> runs/exp{sep}2, runs/exp{sep}3, ... etc.
path = Path(path) # os-agnostic runs/detect/exp
if path.exists() and not exist_ok:
path, suffix = (path.with_suffix(''), path.suffix) if path.is_file() else (path, '') # suffix : ''
# Method 1
for n in range(2, 9999):
p = f'{path}{sep}{n}{suffix}' # increment path
if not os.path.exists(p): #
break
path = Path(p) # 路径中 exp后面带数字 如 exp12
# Method 2 (deprecated)
# dirs = glob.glob(f"{path}{sep}*") # similar paths
# matches = [re.search(rf"{path.stem}{sep}(\d+)", d) for d in dirs]
# i = [int(m.groups()[0]) for m in matches if m] # indices
# n = max(i) + 1 if i else 2 # increment number
# path = Path(f"{path}{sep}{n}{suffix}") # increment path
if mkdir:
path.mkdir(parents=True, exist_ok=True) # make directory
return path2、默认的步长 、 使用cuda
stride = 32 # default stridecommon.py --- 334
cuda = torch.cuda.is_available() and device.type != 'cpu' # use CUDAcommon.py --- 335
3、加载模型以及加载 权重参数
detect.py --- 95
model = DetectMultiBackend(weights, device=device, dnn=dnn, data=data, fp16=half)experimental.py --- 79
attempt_load函数
ckpt = torch.load(attempt_download(w), map_location='cpu') 注意这里的ckpt，其属性如下
说明yolov5s.pt中的文件为字典，主要看这里的model 键值一栏，
所以这里的模型 为 DetectionModel，权重参数已经是训练好的了。直接用就ok。
4、拿出文件夹中的测试图片
detect.py --- 114
for path, im, im0s, vid_cap, s in dataset:此代码会依次执行 LoadImages 类中的 __iter__ 、 __next__，并且在__next__中有读入图片的操作
else:
# Read image
self.count += 1
im0 = cv2.imread(path) # BGR
assert im0 is not None, f'Image Not Found {path}'
s = f'image {self.count}/{self.nf} {path}: '
# 以及下面的转换通道操作
else:
im = letterbox(im0, self.img_size, stride=self.stride, auto=self.auto)[0] # padded resize
im = im.transpose((2, 0, 1))[::-1] # HWC to CHW, BGR to RGB
im = np.ascontiguousarray(im) # contiguous而且最后返回的
return path, im, im0, self.cap, s正好对应上面for in 的5个参数。
5、demo时对输入图片的填充裁剪
augmentation.py --- 111
中的 letterbox 函数，其在LoadImages类中有应用
else:
im = letterbox(im0, self.img_size, stride=self.stride, auto=self.auto)[0] # padded resize 调用的函数
im = im.transpose((2, 0, 1))[::-1] # HWC to CHW, BGR to RGB
im = np.ascontiguousarray(im) # contiguous6、input 进入 model 中的过程
1）首先由 detect.py ---125 进入model
pred = model(im, augment=augment, visualize=visualize)跳转到 DetectMultiBackend 中的forward 函数中，如下所示
2） common.py --- 504
y = self.model(im, augment=augment, visualize=visualize) if augment or visualize else self.model(im)跳转到 DetectionModel 中的 forward 函数中， 如下所示
3） yolo.py --- 206
def forward(self, x, augment=False, profile=False, visualize=False):
if augment:
return self._forward_augment(x) # augmented inference, None
return self._forward_once(x, profile, visualize) 这里 demo 过程不需要数据增强， 会跳转到 self._forward_once(x, profile, visualize) 函数中，这个方法在 BaseModel 父类中定义，所以跳转到 BaseModel 中，如下所示
4）yolo.py --- 114
def _forward_once(self, x, profile=False, visualize=False):
y, dt = [], [] # outputs
for m in self.model: # m 与 model <c-8>
if m.f != -1: # if not from previous layer
x = y[m.f] if isinstance(m.f, int) else [x if j == -1 else y[j] for j in m.f] # from earlier layers
if profile:
self._profile_one_layer(m, x, dt)
x = m(x) # run
y.append(x if m.i in self.save else None) # save output 这里注意 m.i 这个属性
if visualize:
feature_visualization(x, m.type, m.i, save_dir=visualize)
return x这个循环拿出 model 中的一层 来执行的，而不是像pytroch的那种直接 Sequence 完事的。
虽然时执行父类中的方法，不过属性依然可以应用子类中的，比如这个 self.save，来自DetectionModel， yolo.py ---185，如下所示
self.model, self.save = parse_model(deepcopy(self.yaml), ch=[ch])而且，其中的 这个y好像没用是，可能是在可视化中会用到吧，最后输出的只有 x 。
5）最终得到输出 ， 跳回到 2） 中的输出 y，接下来执行
if isinstance(y, (list, tuple)): # Ture
return self.from_numpy(y[0]) if len(y) == 1 else [self.from_numpy(x) for x in y] def from_numpy(self, x):
return torch.from_numpy(x).to(self.device) if isinstance(x, np.ndarray) else x6）最后返回到 1） ，得到pred
