I got this error.How can i fix it.I installed protobuf, compiled it, added to path.There are no files such as 'string_int_label_map.prot'.

Did you do protobuf compilation as in:
https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md#protobuf-compilation

[Futi7]

@fisheess yes i tried it with all protobuf-3.x.x versions last time i did there was string_int_label_map_pb2.py file but still getting this error

[Futi7]

Can someone help me with this problem please im stuck at this error can't move forward.

I just had this problem on a 2nd machine of mine that had a snapshot of the repository on February 14th, 2019. I looked at my 1st machine with a snapshot pulled some time around September 2nd, 2018 and the import works. So some change between these dates is causing the problem.

When I updated my 2nd machine with the protos and utils folders from my 1st machine, the error went away...

I guess i figured it out.I switched to Ubuntu OS from Windows 10 OS.Uninstalled python2.x.x then installed python 3.6 used pip3 for all libraries and executed with python3.Problem might be because of conflicts between python2 libs and python3 libs and the PYTHONPATH you setted.Be sure to install libs for the python version you used(pip for python2,pip3 for python3).Thank you for your answers.

I'am still having the same error, looking into "object_detection.protos" there is no 'string_int_label_map_pb2'. I have already compiled and run protobuf as it reefers in https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md#protobuf-compilation. It seems that the archive is missing.

I am having the same problem.

Similar problem is faced by me where the above mentioned cmds are not helping

[Spidy20]

I got a very easy solution
put this python file in object detection/protos folder:- https://github.com/datitran/object_detector_app/blob/master/object_detection/protos/string_int_label_map_pb2.py

It will solve your error

[Mahesh-Bandi]

also you what you can do is run protoc command, it will create .py files for each .proto files. But make sure that this command run successfully and created .py files for each .proto files in the path object_detection\protos.

protoc object_detection/protos/*.proto --python_out=.'

this short command don't run on windows. so instead of *.proto in the command, mention all .proto files in it and run.

Even if it is not working depend on TF/Objection Detection API version try below:
from utils import label_map_util
replace above line with
from object_detection.utils import label_map_util

or may be issue with this. so just replace it.
from object_detection.protos import string_int_label_map_pb2
replace with
from protos import string_int_label_map_pb2
