python - 用我自己的数据进行tensorflow对象检测，你能帮我吗？

Question

我在 githug 上克隆了 tensorflow 对象检测模型: github link
我想用我自己的数据(331 只萨摩耶狗的图像)训练这个模型，遵循这个博客教程 click here

我的步骤:

1. 创建了 PASCAL VOC 格式的数据集；
2. 下载再训练模型( ssd_mobilenet_v1_coco_11_06_2017.tar.gz )
3. 更改配置文件(ssd_mobilenet_v1_pets.config)
4. 通过以下代码启动训练过程:

   python object_detection/train.py \ --logtostderr \ --pipeline_config_path=./samoyed_test_and_train/training/ssd_mobilenet_v1_pets.config \ --train_dir=./samoyed_test_and_train/data/train.record

---

但我收到错误，我的操作系统是 MacOS，我在 AWS 上试过，同样的问题出现了，你能找出我的错误吗？错误:

Answer 1

train_dir 标志用于指向某个(通常为空)目录，您的训练日志和检查点将在训练期间写入该目录。例如，它可能类似于 train_dir=/tmp/training_directory。看起来您正在尝试将其指向您的数据集 --- 配置文件应该已经指向该数据集。
