类型错误：“NoneType”类型的对象没有 len()、图像 ai 和 yolov3

如何解决类型错误：“NoneType”类型的对象没有 len()、图像 ai 和 yolov3

谷歌搜索错误，我看到有人发布关于修复我的注释的帖子，但这意味着什么。就像我不明白该怎么做一样，我可以看到它“评估了 0 个样本”，这可能是问题所在。除了明显与不同的图像相关之外，验证和训练文件中的注释和图像之间没有区别。感谢您的帮助，谢谢:)

解决方法

我在尝试本教程时遇到了同样的问题 (https://medium.com/deepquestai/train-object-detection-ai-with-6-lines-of-code-6d087063f6ff)

然后我将第 6 行 (object_names_array = ["hololens","google-glass","oculus"]) 中的代码更改为我在制作训练图像时使用的名称 (trainer.setTrainConfig(object_names_array=["rectangle","square","rhombus"])。
