Labelimg: 'Python Application not responding' When I launch labelImg, labelme (pyqt5, python3, macOS 11.0 beta)

[Jaemani]

Hi, I was just trying to use labelImg or labelme to make my own yolo-testing files.

But it doesn't work. I tried installing tutorial from google searching.

These are what I installed (I already updated pip, homebrew)
pyqt5
libxml2
lxml
labelme (from pip)

also [export PYTHONPATH=/usr/local/Cellar/libxml2/2.9.10_1/lib/python3.8/site-packages:/usr/local/Cellar/sip/4.19.24/lib/python3.8/site-packages/:/usr/local/Cellar/pyqt/5.15.1/lib/python3.8/site-packages:$PYTHONPATH]

and
make qt5py3

labelImg was from https://github.com/tzutalin/labelImg.git

When I type
python3 labelImg.py at terminal
It will launched but not responding like this.

And this is labelme installed from pip.
When I type labelme at terminal

I thought 'Okay, maybe I missed something.' and downloaded
(standalone executable/app from:

https://github.com/wkentaro/labelme/releases)

but it wasn't work, too

Is it because of my macOS version?
or I really missed something?

• OS: macOS 11.0 Beta
• PyQt version: pyqt5

Hi, have you solved this issue? I encountered the same issue today after updating the MacOS to Big Sur (11.0). I guess there is some compatibility issue with the new system.

Hi @taozang62 ,
I haven't had a chance to upgrade to Big Sur (11.0) to test

[taozang62]

pip install pyqt5==5.12.1 works for me.

pip install pyqt5==5.12.1 works for me.

Do you mean you reinstalled to old version?

No, I didn't solved that. I found another solution
I used the free application called 'RectLabel' from Appstore to label image

Someone told me this and it helped resolve the issue. Maybe just try to execute this in the terminal. Hope it works for you too,
