导入错误：无法从“google.protobuf”导入名称“runtime_version”

Question

PS D:\RealTimeObjectDetection> python Tensorflow/models/research/object_detection/model_main_tf2.py --model_dir=Tensorflow/workspace/models/my_ssd_mobnet --pipeline_config_path=Tensorflow/workspace/models/my_ssd_mobnet/pipeline.config --num_train_steps=10000

ImportError: cannot import name 'runtime_version' from 'google.protobuf' (C:\Users\varda\AppData\Local\Programs\Python\Python311\Lib\site-packages\google\protobuf\__init__.py)

是版本错误吗？我还尝试在用户变量中设置 PYTHONPATH 变量，但编译器仍在查找 object_detection 文件的站点包，而我将路径设置为 D 驱动器中的不同位置

最近发布的 NumPy 2.0 给依赖旧版本 NumPy 的软件包带来了一些问题。要查看安装了哪个版本的 numpy，请运行

pip list

在命令行中。输出示例：

Package Version
------- -------
numpy   2.0.0
pip     24.1

要降级到旧版本：

pip install numpy==1.26.4
