我正在使用Tensorflow Object Detection API重新训练mobilenet v2 SSD，我在Windows和Ubuntu环境中都遇到了这个特殊错误。
我的环境是Windows 10，包括python 3.5，cuda 9.0和tensorflow-gpu 1.6。我用protobuf 3.4.0编译了protobuf
我做了installation test并且没关系，所以现在我正在尝试使用自己的数据集并收到google.protobuf.text_format.ParseError: 108:7 : Message type "object_detection.protos.SsdFeatureExtractor" has no field named "batch_norm_trainable".错误。
我尝试的事情：
整个错误代码：

# well as the label_map_path and input_path fields in the train_input_reader and

我上个月在ubuntu上成功培训了mobilenetv1 ssd模型，今天从头开始安装存储库后，我开始遇到这个错误。
我很感激任何帮助！谢谢！
答案 0 :(得分：14)
对于ssd mobilenet v2，您可以删除“batch_norm_trainable：true”，因为此字段现已弃用。
