TagLab crashing when trying to use 4-clicks or Split screen

[JohnStratford]

Hi,

Whenever I try to use the '4-clicks segmentation' tool or activate the 'Split screen' function' TagLab freezes for a few minutes then crashes and closes. When this happens, this error message is returned in the Windows Powershell I used to launch the software:

1. After trying to use '4-clicks segmentation':

PS C:\Users\Downloads\TagLab + required packages\TagLab-main> python.exe taglab.py

2. After activating the 'Split screen' function':

self.horizontalScrollBar().setValue(posx)
TypeError: setValue(self, a0: int): argument 1 has unexpected type 'float'

(I am using Windows 11, and I have installed 64-bit Python 3.10.11, CUDA Toolkit 11.6 and the x64 Visual Studio Redistributable.)
Does anyone know what is causing these errors and how I can fix them?
Thanks for your help!

I am getting this exact same crash and errors after trying to use '4-clicks segmentation'. This error is happening once a project with associated map (.jpg) and labels are loaded. The error is triggered as soon as the user presses the 4-clicks icon.

I tried editing the drawline() method, in the QtImageViewerPlus.py file, to explicitly accept floats or int in different combinations depending on the errors thrown:
#used for crossair cursor def drawForeground(self, painter, rect): if self.showCrossair: painter.setClipRect(rect) pen = QPen(Qt.white, 1) pen.setCosmetic(True) painter.setPen(pen) #painter.drawLine(self.mouseCoords.x(), rect.top(), self.mouseCoords.x(), rect.bottom()) #painter.drawLine(rect.left(), self.mouseCoords.y(), rect.right(), self.mouseCoords.y()) painter.drawLine(int(self.mouseCoords.x()), float(rect.top()), int(self.mouseCoords.x()), float(rect.bottom())) painter.drawLine(float(rect.left()), int(self.mouseCoords.y()), float(rect.right()), int(self.mouseCoords.y()))

However, this is still throwing a similar error:

Traceback (most recent call last):
File "c:\Users\user\Downloads\TagLab-main\source\QtImageViewerPlus.py", line 629, in drawForeground
painter.drawLine(int(self.mouseCoords.x()), float(rect.top()), int(self.mouseCoords.x()), float(rect.bottom()))
TypeError: arguments did not match any overloaded call:
drawLine(self, l: QLineF): argument 1 has unexpected type 'int'
drawLine(self, line: QLine): argument 1 has unexpected type 'int'
drawLine(self, x1: int, y1: int, x2: int, y2: int): argument 2 has unexpected type 'float'
drawLine(self, p1: QPoint, p2: QPoint): argument 1 has unexpected type 'int'
drawLine(self, p1: Union[QPointF, QPoint], p2: Union[QPointF, QPoint]): argument 1 has unexpected type 'int'

It might be that the values being passed into self.mouseCoords.x(), rect.top(), self.mouseCoords.y(), and rect.bottom() aren't explicitly set in the code. Do they come from another source? It may be worth investigating how they're calculated and, further to the error messages, making sure that they are the correct types before passing them to drawLine().

Hi,

the combination of Python 3.10.x and new version of Qt cause this issue. We can fix it but it requires a lot of work, so for the moment, I suggest to uninstall Python 3.10, install Python 3.9, and then re-install TagLab by running again install.py

Please, let me know if this solve.

Best
Massimiliano

Hi @maxcorsini,

This worked! - I am now using Python 3.9 in my conda environment :)

Thank you very much.
My regards,
Damaris
