python - 如何解决 "AttributeError: module ' google.protobuf.descriptor' has no attribute '_internal_create_key"？

我在 jupyter notebook 中执行 from object_detection.utils import label_map_util 时遇到了它。其实就是tensorflow对象检测教程notebook(自带tensorflow对象检测api)
完整的错误日志:

AttributeError: module 'google.protobuf.descriptor' has no attribute '_internal_create_key'

最佳答案

我通过 pip show protobuf 和 protoc --version 得到的 protoc 版本是不同的。 pip 中的版本有点过时了。
在我升级了 pip 版本之后

pip install --upgrade protobuf

问题解决了。
