Error -- QtImageViewer.py -- argument 1 has unexpected type 'float'

[jjherlan]

Hello from NYC,

I am currently trying to segment corals from reefs at Rapa Nui (Easter Island) as part of my PhD research.

I am using a .png file - RGB,- 8357 x 20876 pixels.

• Cuda compilation tools, release 11.8, V11.8.89
• Python 3.10.10
• Ubuntu 22.04 LTS (WSL2)
• TagLab 2023.5.17

Although, I do get this when checking PyTorch version in Python:
torch.version
'2.1.0.dev20230701+cu121'

Anyway, I get the following error when clicking in the Map Preview pane =

Traceback (most recent call last):
File "/home/jherlan/TagLab/source/QtImageViewer.py", line 247, in center
self.horizontalScrollBar().setValue(posx * zf)
TypeError: setValue(self, a0: int): argument 1 has unexpected type 'float'

And, the following error when clicking the 4-click segmentation tool =

Traceback (most recent call last):
File "/home/jherlan/TagLab/source/QtImageViewerPlus.py", line 627, in drawForeground
painter.drawLine(self.mouseCoords.x(), rect.top(), self.mouseCoords.x(), rect.bottom())
TypeError: arguments did not match any overloaded call:
drawLine(self, l: QLineF): argument 1 has unexpected type 'float'
drawLine(self, line: QLine): argument 1 has unexpected type 'float'
drawLine(self, x1: int, y1: int, x2: int, y2: int): argument 1 has unexpected type 'float'
drawLine(self, p1: QPoint, p2: QPoint): argument 1 has unexpected type 'float'
drawLine(self, p1: Union[QPointF, QPoint], p2: Union[QPointF, QPoint]): argument 1 has unexpected type 'float'
Aborted

Any suggestions would be appreciated, thank you in advance.

Regards,
James

Hi jjherlan,

since Python 3.10.x, Python introduces type checking. These checks create problems with PyQt, since sometime an integer is expected and not a floating point number. To fix this problem, simply go in the code and put int(..) around the argument, i.e. setValue( int(posx*zf) ).
I am worried that this is not sufficient and the same error will appear in other places. The only viable solution, for the moment, is
to downgrade your Python version to 3.9 and reinstall Taglab.

Ok, thank you for the assistance. I will downgrade and reinstall.
