Someone?

why?

• ubuntu22.04
• pyqt5
• python3.10

Did you use following code to install pip install labelImg ? Because there is a bug to install with pip.

[SperenzaNarra]

you need to use python3.8

Is there a fix coming any time soon?

I got the same problem, did you solve it?

[HuyPham55]

I met the same problem, can't create any ractangle for labeling at all

 p.drawLine(self.prev_point.x(), 0, self.prev_point.x(), self.pixmap.height())
TypeError: arguments did not match any overloaded call:
  drawLine(self, QLineF): argument 1 has unexpected type 'float'
  drawLine(self, QLine): argument 1 has unexpected type 'float'
  drawLine(self, int, int, int, int): argument 1 has unexpected type 'float'
  drawLine(self, QPoint, QPoint): argument 1 has unexpected type 'float'
  drawLine(self, Union[QPointF, QPoint], Union[QPointF, QPoint]): argument 1 has unexpected type 'float'

I'm running into the same thing now that I upgraded to Ubuntu 22.04. installed via pip Python 3.10.6 PyQt5 5.15.7 PyQt5-Qt5 5.15.2 PyQt5-sip 12.11.0 labelImg 1.8.6

Same here: Python 3.10.6 labelImg 1.8.6

Creating a rectangle (just press w) makes the program crash with that error. Any fix ?

[rokopi-byte]

It's a duplicate of this. There is also a workaround.

I faced the same issue. The error was because of a dependency conflict in Ubuntu 22.04. Creating a virtual environment for labelImg solved this problem.

[kkedich]

Same as @esraa-abdelmaksoud and this comment. Installing a separate environment was enough to not see the error again. My setup: Ubuntu 22.04 and python 3.11.5

conda create -n labelImg python=3.8
pip3 install labelImg
