所以我正在关注sentdex的对象检测教程,我已经到了你应该导出推理图的步骤.我正在使用Tensorflow的object_detection文件夹中的“export_inference_graph.py”脚本.
问题是我得到了这个ValueError：

Traceback (most recent call last):
  File "C:UsersZelcore-DatorAppDataLocalProgramsPythonPython35libsite-packagesgoogleproto
bufinternalpython_message.py",line 545,in _GetFieldByName
    return message_descriptor.fields_by_name[field_name]
KeyError: 'layout_optimizer'

During handling of the above exception,another exception occurred:

ValueError: Protocol message RewriterConfig has no "layout_optimizer" field.

我猜它与protobuf有关,但我已经多次重新安装它并没有成功.
所有帮助赞赏

解决方法

也发生在我身上.几周前没有发生过.
在修复错误之前,您可以使用仍然有效的早期版本.
替换’object_detection / exporter.py’中的第72行：

layout_optimizer=rewriter_config_pb2.RewriterConfig.ON)

与旧的和工作线：

optimize_tensor_layout=True)
