我在64位Windows 10和Python 3.6上使用tensorflow object_detection api。我已经安装了protobuf和所有其他必要的软件包，并且在我的路径中安装了protoc和所有其他/model/research files。我的string_int_label_map_pb2.py文件夹中有object_detection/protos，但是我仍然遇到ImportError: cannot import name 'string_int_label_map_pb2'错误。有趣的是，当我打开一个新的Python窗口时，仍然无法使用命令from object_detection.protos import (random file in protos here)导入任何protos文件。我尝试了所有可以在网上找到的解决方案。
错误代码：
