==训练==训练的步骤参考：[https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/running_locally.md Running Locally] 其中，使用自己的数据集需要生成labelmap和tfrecord：[https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/using_your_own_dataset.md label_mapOwn Dataset] pipeline的配置文件参考：[https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/configuring_jobs.md Pipeline]样例包括：[https://github.com/tensorflow/models/tree/master/research/object_detection/samples/configs config_samples] 可用的pretrain模型参考：[https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/detection_model_zoo.md Model Zoo] 建议使用速度为fast的模型。
