Jan*_*isl 7 python deep-learning tensorflow object-detection-api tensorflow2.0
我正在尝试开始使用 Tensorflow 2.0 Object Detection API。我按照官方教程完成了安装,并通过了所有测试。但是,当我尝试运行主模块时,我不断收到我不明白的错误消息。这是我运行它的方式:
python model_main_tf2.py --model_dir=ssd_resnet50_v1_fpn_640x640_coco17_tpu-8 --pipeline_config_path=ssd_resnet50_v1_fpn_640x640_coco17_tpu-8/pipeline.config

这是错误消息的开头:

在pipeline.config 中,我指定了一个这样的检查点:

我已经搜索过谷歌,但找不到任何答案。在此问题中,建议的解决方案已过时(他们建议替换的代码不再存在)。
问题:这是什么问题,我该如何解决?
我在装有 CentOS Linux 7 的服务器上执行此操作。我使用的是 Python 3.7。我是 Tensorflow 的新手,所以如果我遗漏了任何重要信息,请告诉我。

从您提供的文件名 (ssd_resnet50_v1_fpn_640x640_coco17_tpu-8),我可以看到您正在尝试使用对象检测任务。因此,在您的 pipeline.config 文件中更改这一行:
fine_tune_checkpoint_type: "classification"

到:
fine_tune_checkpoint_type: "detection"

这应该可以解决您的问题。
