无法在 Windows 上运行对象检测器问题导入错误：无法从“object_detection.protos”导入名称“string_int_label_map_pb2” 从 YML 创建环境

问题描述

我正在尝试设置 tensorflow OD 包，并尝试从 repo 安装它，但它似乎不起作用。

我按照安装步骤 (object_detection) 操作并尝试运行测试文件 object_detection.builders.model_builder_tf2_test.py，但无济于事。

1. 无法识别 protoc 可执行文件
2. 我曾收到一条 tf_utils missing 消息
3. 最后得到了 ImportError: cannot import name 'string_int_label_map_pb2' from 'object_detection.protos'

我是这个工具的新手，有人遇到过这些问题吗？

我发现了这些相关问题并尝试了几件事，但我向前迈出的每一步都会解开另一个问题。

• Object Detection API error: "ImportError: cannot import name anchor_generator_pb2"
• https://github.com/tensorflow/models/issues/2930

解决方法

经过一些尝试，从一个新环境开始，我整理了使其工作的步骤。

从 YML 创建环境

1. 使用此准系统设置创建新环境（请参阅下面的代码段）
2. 克隆对象检测器 (OD) 存储库
   • 按照此处的说明操作：https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf2.md#python-package-installation
     • git clone https://github.com/tensorflow/models.git
3. 下载 protobuf (google) win64 ZIP
   • https://github.com/protocolbuffers/protobuf/releases/download/v3.15.1/protoc-3.15.1-win64.zip
   • 解压
   • 从bin/复制protoc.exe到C:\Windows\System32
   • 通过在命令提示符下运行 protoc 进行测试
4. 从 {rootdir} 运行下面的代码

   cd models/research
   # Compile protos.
   protoc object_detection/protos/*.proto --python_out=.
   # Install TensorFlow Object Detection API.
   cp object_detection\packages\tf2\setup.py .
   # Step below is important even if some comments online (2021-02-23) suggest it is deprecated
   python -m pip install --use-feature=2020-resolver .
   # The step below was added,after unsuccessful previous attempts,from [this related issue][1]
   pip install .
   

5. 要验证设置，请运行以下任一操作
   • python object_detection.builders.model_builder_tf2_test.py
   • import object_detection.builders.model_builder_tf2_test
