ImportError: cannot import name 'string_int_label_map_pb2'

[bsrinivas84]

In step "Object detection imports" I am getting the following error

ImportError Traceback (most recent call last)
in ()
----> 1 from utils import label_map_util
2
3 from utils import visualization_utils as vis_util
D:\Personal\learn\ML\DL\Tensorflow\Official-Tutorial\models-master\object_detection\utils\label_map_util.py in ()
20 import tensorflow as tf
21 from google.protobuf import text_format
---> 22 from object_detection.protos import string_int_label_map_pb2
23
24
ImportError: cannot import name 'string_int_label_map_pb2'

To workaround/proceed I commented the following line in "label_map_util.py"
from object_detection.protos import string_int_label_map_pb2

But I am now getting error at step "Loading label map"
NameError: name 'string_int_label_map_pb2' is not defined

So need your help to solve the error in step "Object detection imports"
Appreciate the help to proceed further

Make sure you run protoc object_detection/protos/*.proto --python_out=. as mentioned in installation instructions: https://github.com/tensorflow/models/blob/master/object_detection/g3doc/installation.md

Thanks mat for the quick response.
I am unable to locate the tensorflow/models directory.

Couple of hits got me to these links, but It did not help me find the directory
tensorflow/tensorflow#5953
tensorflow/tensorflow#5953

For windows OS, the steps need to be better?
Please help

@bsrinivas84 tensorflow/models refers to the root of the git checkout.

Thanks Derek, realized first I had to install protoc-3.2.0-windows-x86_64.exe from https://github.com/google/protobuf/releases (pointed environment variables to include the path to installation) and then go to root and run the command. It worked, Many Thanks

Anybody who is getting an import error in Jupyter notebook even after updating the PYTHONPATH make sure you restart the notebook. (i wasted couple of hours trying to chase down this problem)

[bsrinivas84]

Mahesh which error are you getting? If its the protof please follow the instructions here to install as pointed above
https://github.com/tensorflow/models/blob/master/object_detection/g3doc/installation.md

Also make sure you re-download the latest version of code

i am still beginner i am trying to install tensorflow object detection API on windows i followed the instruction like that :

1. I installed protoc
2. protoc object_detection/protos/*.proto --python_out=.
3. set PYTHONPATH=$PYTHONPATH:pwd:pwd/slim
4. but i am getting this error:

yes, i got the same error as 4saad mentioned, i checked the builder folder, where i found the anchor_generator-pb2.py which it has already been there, i still got the error like this

[songwg188]

I also got the same error as 4saad mentioned that cannot import name 'anchor_generator_pb2' even if i found the file of ' anchor_generator-pb2.py'.
However,when i come into python environment in cmd, from object_detection.protos import anchor_generator_pb2 is correct.

C:\Users\swg\Anaconda3\Lib\site-packages\tensorflow\models>python
Python 3.5.2 |Anaconda 4.2.0 (64-bit)| (default, Jul 5 2016, 11:41:13) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from object_detection.protos import anchor_generator_pb2
>>>
In this case, It can work.

Hi songwg188, do you found any solution for the issue? I have also faced same problem as you mentioned. import is working from python environment, but I couldn't run the following command:
python object_detection/builders/model_builder_test.py from command prompt. Any help will be appreciable

[yuye1992]

i had the same error,but i solved it. make sure your protoc version >=2.6,download tensorflow/model to a new folder ,and re-install it.
