我正在尝试运行这里看到的宠物探测器google cloud示例：https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/running_pets.md，并且在我实际尝试运行训练之前得到大部分路径，直到我运行命令：
gcloud ml-engine jobs submit training `whoami`_object_detection_`date +%s` \
--runtime-version 1.2 \
--job-dir=gs://test-run-2/train \
--packages dist/object_detection-0.1.tar.gz,slim/dist/slim-0.1.tar.gz \
--module-name object_detection.train \
--region us-central1 \
--config object_detection/samples/cloud/cloud.yml \
-- \
--train_dir=gs://test-run-2/train \
--pipeline_config_path=gs://test-run-2/data/pipeline.config
这不可避免地导致错误：
Traceback (most recent call last):

我不确定我在这里做错了什么或错误来自哪里，因为我在preprocessor_pb2.py文件中看不到。任何帮助将不胜感激！

进入这个问题 - 可能是因为在尝试在1.2上运行作业时使用更新的tensorflow dist（1.4）。我通过传入一个设置它的yaml配置文件来解决它：
trainingInput:
runtimeVersion: "1.4"
pythonVersion: "3.5"
如果遇到matplot lib导入错误，您需要立即关注：https://github.com/tensorflow/models/issues/2739#issuecomment-351213863，直到tensorflow模型repo修复它。

在将tensorflow升级到1.11版并运行后解决了此问题：
pip install --upgrade protobuf
答案 2 :(得分：-1)
@olive_tree有一个很好的答案，最终成为我的问题的是我正在编译的protobuf的版本。确保protoc版本与此处描述的正确版本匹配：https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md
这是我最终必须运行（在OSX上）
brew uninstall protobuf
brew install protobuf@2.6
