labelImg command error: AssertionError: Missing string id : useDefaultLabel

[ShubhamAvasthi]

• OS: Ubuntu
• PyQt version: PyQt5

labelImg command gives me the following error on my installation and I am unable to figure out a fix for the problem:

Traceback (most recent call last): File "/usr/local/bin/labelImg", line 11, in <module> sys.exit(main()) File "/home/shubham/.local/lib/python3.6/site-packages/labelImg/labelImg.py", line 1473, in main app, _win = get_main_app(sys.argv) File "/home/shubham/.local/lib/python3.6/site-packages/labelImg/labelImg.py", line 1466, in get_main_app argv[3] if len(argv) >= 4 else None) File "/home/shubham/.local/lib/python3.6/site-packages/labelImg/labelImg.py", line 130, in __init__ self.useDefaultLabelCheckbox = QCheckBox(getStr('useDefaultLabel')) File "/home/shubham/.local/lib/python3.6/site-packages/labelImg/labelImg.py", line 95, in <lambda> getStr = lambda strId: self.stringBundle.getString(strId) File "/home/shubham/.local/lib/python3.6/site-packages/libs/stringBundle.py", line 36, in getString assert(stringId in self.idToMessage), "Missing string id : " + stringId AssertionError: Missing string id : useDefaultLabel

Did you forget to make ?
Try make qt5py3

[Partha2k]

I am having the same issue.
Platform: Windows + Anaconda
PyQt Version: pyqt 5

[zh7117]

I cant make.
but I tried :
pyrcc5 -o resources.py resources.qrc

and then it works.

I am having the issue as well

[AdritaBarari]

I was having the same issue on WIndows 10 + Anaconda platform with python 3.6. but as @zh7117 suggested
pyrcc5 -o resources.py resources.qrc works

[wuqingshan2010]

i had tried it, we must cd into the LabelImg file and input the command "pyrcc5 -o resources.py resources.qrc"

[tzutalin]

There are new changes related to the resource. In general, it has to compile the resource again.
Go to the root, and run:
make qt5py3 or make qt4py2

how to solve

[ZidaneQi]

After tried all methods above (didn't work), I found out the solution.
(both MacOS Mojave and Catakiina, Python3, PyQt5)

cd into the LabelImg file and input the command: make all

then: python labelimg.py

[yasersakkaf]

In Windows + Anaconda installations, I am getting the same error.
Any solution found?

$>python labelImg.py

I faced same issue and solving it like this:

1- typing in cmd:

cd path_to_lablelImg_folder
pyrcc5 -o resources.py resources.qrc

2- Change the location of resources.qrc and resource files to libs folder.

3- typing in cmd:

cd path_to_lablelImg_folder/libs
pyrcc5 -o resources.py resources.qrc
cd ..
python labelImg.py

I hope this help to all.
-notice: every line is separate command and my Platform is: Windows + Anaconda

I am facing the same problem even after following the above solution!!!

1. I Cloned the repository.
2. Used these commands pyrcc5 -o libs/resources.py resources.qrc python labelImg.py
3. Still error :
   labelImg\libs\stringBundle.py", line 47, in get_string assert(string_id in self.id_to_message), "Missing string id : " + string_id AssertionError: Missing string id : useDefaultLabel

[snigdhasaha7]

Same here - I have tried everything above and I'm still facing the error.

For reference, I'm running on the conda environment on Windows.

Here's my error to be specific:

Traceback (most recent call last):
File "labelImg.py", line 1649, in
sys.exit(main())
File "labelImg.py", line 1645, in main

Hello all,

If above solutions did not work, try installing this version instead :

cd [YOUR FOLDER]
git clone https://github.com/peoplecure/labellmg.git

cd [FOLDER CONTAINING labellmg]

brew install python3
pip3 install pipenv
pipenv run pip install pyqt5==5.15.2 lxml
pipenv run make qt5py3
pipenv run python3 labelImg.py
[Optional] rm -rf build dist; python setup.py py2app -A;mv "dist/labelImg.app" /Applications

Fyi, I'm using macOS

[Rurouni-z]

conda create a virtual env， then pip install labelimg then labelimg finally it worked.
my python version=3.6 use Windows

[AhmadMuhamed]

conda create a virtual env， then pip install labelimg then labelimg finally it worked. my python version=3.6 use Windows

[AhmadMuhamed]

Here is the solution worked for me :
conda create -env labelimg
conda activate labelimg
pip install labelimg
labelimg

[JulianToppo]

conda create a virtual env， then pip install labelimg then labelimg finally it worked. my python version=3.6 use Windows

Thanks a lot man! 💯 It worked but i still can't figure out why would it throw an error when the already existing virtual env i created had all the required files.

Thank you. I'm using Windows but this solution works for me. I just changed

brew install python3
pip3 install pipenv
pipenv run pip install pyqt5==5.15.2 lxml
pipenv run make qt5py3
pipenv run python3 labelImg.py
[Optional] rm -rf build dist; python setup.py py2app -A;mv "dist/labelImg.app" /Applications

this part. Instead of,

pyrcc5 -o resources.py resources.qrc
python labelImg.py
