1.代码下载地址GitHub - WongKinYiu/yolov9: Implementation of paper - YOLOv9: Learning What You Want to Learn Using Programmable Gradient Information
2.准备自己的数据集
这里数据集我以SAR数据集为例
具体的下载链接如下所示：
链接：https://pan.baidu.com/s/1cIiaOT2hbnQsa8e93cHQrg
提取码：yyds
3.数据集路径调整
将数据集存放在yolov9的文件夹下面
4.新建data.yaml文件
train: E:\liqiang\yolov9-main\data\SSDD\train\images # 训练集绝对路径 进入到训练集存放图片的文件夹里面，按ctrl+L复制过来即可 val: E:\liqiang\yolov9-main\data\SSDD\val\images # 验证集绝对路径 进入到验证集存放图片的文件夹里面，按ctrl+L复制过来即可 # test: D:\needed\air-filter\train\imagesnc: 1 # class数 names: ['ship'] # 模型类别名train的路径是训练集下面的images路径
val的路径是验证集下面的images路径
其他的根据自己的数据集进行调整
5.修改yolov9.yaml文件
把nc改为数据集类别即可
6.训练
报错1：
训练如果出现AttributeError: 'list' object has no attribute 'view'报错时，使用tain_dual.py进行训练，不要使用train.py进行训练

AttributeError: 'list' object has no attribute 'view'
报错2：
AttributeError: 'FreeTypeFont' object has no attribute 'getsize'
解决：
pip install Pillow==9.5 -i https://pypi.douban.com/simple/训练命令：
python .\train_dual.py --cfg E:\liqiang\yolov9-main\models\detect\yolov9.yaml --data E:\liqiang\yolov9-main\data\data.yaml --device 0 --batch-size 4 --epoch 10 --hyp E:\liqiang\yolov9-main\data\hyps\hyp.scratch-high.yamlyolov9.yaml绝对路径复制
data.yaml绝对路径复制
hyps绝对路径复制
7.推理
python detect.py --weights E:\liqiang\yolov9-main\runs\train\exp11\weights\best.pt --source E:\liqiang\yolov9-main\data\images\000002.jpg报错：AttributeError: 'list' object has no attribute 'device'
解决：
将general.py中的：
if isinstance(prediction, (list, tuple)): # YOLO model in validation model, output = (inference_out, loss_out)prediction = prediction[0] # select only inference outputdevice = prediction.device
替换为：
if isinstance(prediction, (list, tuple)):processed_predictions = [] for pred_tensor in prediction:processed_tensor = pred_tensor[0] processed_predictions.append(processed_tensor) prediction = processed_predictions[0]device = prediction.device
结果如下：
