yolov9数据集分类报错FileNotFoundError: [Errno 2] No such file or directory:

FileNotFoundError: [Errno 2] No such file or directory: ‘Q:\M\yolov9\datasets\metalfittings\labels\12_000150.JPG.txt’
ERROR conda.cli.main_run:execute(125): conda run python Q:\M\yolov9\datasets\fish\splitDataset.py failed. (See above for error)
修改def toLabelPath函数

def toLabelPath(img_path, label_path):
    img = img_path.split('\\')[-1]
    label = img.split('.jpg')[0] + '.txt'
    return os.path.join(label_path, label)

修改为

def toLabelPath(img_path, label_path):
    # 获取文件名，包括扩展名
    img = img_path.split('\\')[-1]
    
    # 分割文件名和扩展名，不区分大小写
    parts = img.lower().split('.')
    
    # 确保文件名和扩展名正确分离
    if len(parts) > 1:
        filename = '.'.join(parts[:-1])  # 文件名，不包含扩展名
        extension = parts[-1].upper()    # 扩展名，统一为大写
    else:
        filename = img
        extension = ''

    # 构造标签文件名，将扩展名替换为 'txt'
    label = f'{filename}.txt'
    
    # 返回完整的标签文件路径
    return os.path.join(label_path, label)
