YOLOV9训练自己的数据集_pred_distri, pred_scores = torch.cat([xi.view(feat

 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\images
 
nc: 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.yaml

yolov9.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 output
 
    device = 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：
