我是Tensor Flow的新手。我正在尝试使用MobileNet SSD模型进行训练来检测两个类。但是，在进行了大约300个步骤的培训后，我遇到了ResourceExhausted错误。我无法弄清楚解决此问题需要做什么。 这是train.py文件：

r"""Training executable for detection models.
This executable is used to train DetectionModels. There are two ways of
configuring the training job:
1) A single pipeline_pb2.TrainEvalPipelineConfig configuration file
can be specified by --pipeline_config_path.
Example usage:
./train \
--logtostderr \
--train_dir=path/to/train_dir \
--pipeline_config_path=pipeline_config.pbtxt
2) Three configuration files can be provided: a model_pb2.DetectionModel
configuration file to define what type of DetectionModel is being trained, an
input_reader_pb2.InputReader file to specify what training data will be used and
a train_pb2.TrainConfig file to configure training parameters.
Example usage:
./train \
--logtostderr \
--train_dir=path/to/train_dir \
--model_config_path=model_config.pbtxt \
--train_config_path=train_config.pbtxt \
--input_config_path=train_input_config.pbtxt

我已按照本Youtube教程来训练自己的对象检测模型。请提出解决此问题的建议。预先感谢。
