我想使用 ssd_mobilenet_v2_coco_2018_03_29 训练我的 tensorflow 对象检测模型。当我运行训练步骤时:
python object_detection/train.py --logtostderr--train_dir=train
--pipeline_config_path=ssd_mobilenet_v2_coco_2018_03_29/pipeline.config
它抛出

在这里,我使用了 2 个类。我从https://github.com/tensorflow/models/blob/master/research/object_detection/samples/configs/ssd_mobilenet_v2_coco.config复制了配置文件 我的 Tensorflow 版本:1.12.0 protobuf:3.6.1
