cannot import name 'string_int_label_map_pb2'

Question

My goal is to run tensorflow object detection API and followed the steps in the installation.

I install the tensorflow object detection API and protobuf. I have also added the path to protobuf. But the following error shoots up:

ImportError: cannot import name 'string_int_label_map_pb2'

Installed protobuf :

%%bash
cd models/research
protoc object_detection/protos/*.proto --python_out=.

A block of code containing the error import statements:

from object_detection.utils import ops as utils_ops
from object_detection.utils import label_map_util
from object_detection.utils import visualization_utils as vis_util

Solution 1

Install protoc-3.11.4 from https://github.com/google/protobuf/releases

and run protoc object_detection/protos/*.proto --python_out=. as mentioned in the installation instructions. And put this file in in object detection/protos

Solution 2

You can try this suggestion in the same order

see models/issues/1962# Or

git clone https://github.com/tensorflow/models.git
cd models/research

protoc -I=./ --python_out=./ ./object_detection/protos/*.proto
export PYTHONPATH=$PYTHONPATH:`pwd`:`pwd`/slim

import sys
sys.path.append('/content/models/research/object_detection') # ~/tensorflow/models/research/object_detection

#try import now..
from utils import label_map_util

I run those cmds. But still the same error pop up and i use 3.6.1 version

@SaiKrishnadas if this is not working then put this file in in object detection/protos

@SaiKrishnadas Replace and try

@SaiKrishnadas last thing I can advise is to follow this tutorial and make sure protoc-3.11.4 is installed in your Coumputer
