python – 导出推理图时出错(ValueError)

2023年8月26日 194次阅读

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:\Users\Zelcore-Dator\AppData\Local\Programs\Python\Python35\lib\site-packages\google\proto
buf\internal\python_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

最佳答案 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)
