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
TagLab 2023.5.17
Traceback (most recent call last):

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

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

self.horizontalScrollBar().setValue(posx)

(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!

What version of pyqt5 is installed in your python environment? It's not necessarily a fix, but if you haven't already tried, maybe uninstall and re-install pyqt5

[damarislanders]

Hey thanks for your answer. I am using pyqt5 5.15.10. I uninstalled and reinstalled but the error still occurs when clicking 4-clicks tool.

Yeah no issue there I guess. Are you using an Anaconda environment to install TagLab's dependencies, or is everything being installed in your base python environment? If you're using an conda environment, I have a fork I made for my team to help install TagLab because it was always giving them issues. I'm not sure if the issue you're dealing with has to do with dependencies at all, but I'm currently running the same version of TagLab and it seems to be running okay.

Maybe try cloning my fork and installing using the install script just as a sanity check?

Dear damarislanders,

this types of error is caused by the data type checking of Python 3.10.x . Fix this problems require a lot of work, so for the moment a quick workaround is to change Python version, for example going back to the 3.9. After this, you need to re-run Taglab's install.py to re-install the packages.

Let me know if this works.

Best,
Massimiliano
