Same here. Ubuntu 22.04, installed with pip3.

• labelImg 1.8.6
• python 3.10.4

The manual installation from the start page works.

[Logiase]

same error on Windows, installed with pip

• python 3.10.5
• labelimg 1.8.6

[Tylermarques]

Same issue with me. Solution was to use python3.8 for me.

conda create -n labelImg python=3.8
pip3 install labelImg
python3 $HOME/miniconda3/envs/labelImg/bin/labelImg

Solution. Error in Qt5. float to int conversion Changed: x:\xxxxx\python-310\Lib\site-packages\libs\canvas.py 526 line: default: p.drawRect(left_top.x(), left_top.y(), rect_width), int(rect_height) new: p.drawRect(int(left_top.x()), int(left_top.y()), int(rect_width), int(rect_height)) 530 line: default: p.drawLine( self.prev_point.x(), 0, self.prev_point.x(), self.pixmap.height()) new: p.drawLine( int(self.prev_point.x()), 0, int(self.prev_point.x()), int(self.pixmap.height())) 531 line: default: p.drawLine( 0, self.prev_point.y(), self.pixmap.width(), self.prev_point.y()) new: p.drawLine( 0, int(self.prev_point.y()), int(self.pixmap.width()), int(self.prev_point.y())) Changed: x:\xxxxx\python-310\Lib\site-packages\labelImg\labelImg.py 965 line: default: bar.setValue(bar.value() + bar.singleStep() * units) new: bar.setValue(int(bar.value() + bar.singleStep() * units))

Good work.
