解决步骤 #

• 对齐依赖版本
  该错误多由依赖包版本冲突导致，尤其是dacite和FiftyOne的版本不兼容：

  1. 卸载现有冲突包：

     pip uninstall -y fiftyone dacite strawberry-graphql graphql-core
     

  2. 重新安装稳定兼容版本：

     pip install fiftyone
     

     若问题仍存在，指定dacite的兼容版本：

     pip install dacite==1.8.1
     

• 清理FiftyOne缓存与损坏元数据
  数据集元数据或本地缓存损坏可能触发加载错误：

  1. 关闭所有FiftyOne进程，删除本地缓存目录（Windows命令）：

     rmdir /s /q C:\Users\aidan\AppData\Local\fiftyone
     

  2. 重新导入数据集：

     import fiftyone as fo
     # 删除现有损坏数据集
     fo.delete_dataset("你的数据集名称")
     # 重新从目录导入（根据数据集类型调整参数）
     dataset = fo.Dataset.from_dir(
         dataset_dir="你的数据集路径",
         dataset_type=fo.types.COCODetectionDataset
     )
     dataset.save()
     

• 验证Python版本兼容性
  确认使用的Python3.11与FiftyOne版本兼容：FiftyOne从v0.17.0开始支持Python3.11，若你的FiftyOne版本低于此，升级至最新稳定版即可。

• 检查数据集完整性
  确认数据集的图像文件、标注文件无损坏或缺失，可尝试用一个小型测试数据集启动FiftyOne，排查是否是原数据集本身的问题。
