Tensorflow 错误：协议消息 ConvolutionalBoxPredictor 没有字段 box_encodings_clip_range

我是 Tensorflow 新手，正在尝试简单教程用于进行迁移学习。

当我尝试通过以下命令启动训练时：

python train.py --logtostderr --train_dir=training/ --pipeline_config_path=training/ssd_mobilenet_v2_coco.config

我收到以下错误：

我不知道这是什么意思。有人知道这是什么以及是什么原因造成的吗？

检查安装指南：https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md

您可能没有运行 protoc。

如果你使用的是 Linux：

下载并安装 protoc 3.0 版本，然后解压文件。

# From tensorflow/models/research/
wget -O protobuf.zip https://github.com/google/protobuf/releases/download/v3.0.0/protoc-3.0.0-linux-x86_64.zip
unzip protobuf.zip

再次运行编译过程，但使用下载的 protoc 版本

 # From tensorflow/models/research/
 ./bin/protoc object_detection/protos/*.proto --python_out=.
