RuntimeError in 1.8.1: connected components: Need more labels than can be represented in the destination type.

[PauCasanova]

Good afternoon,

I am running the 1.8.1 version of plantseg on a linux Mint 22 machine.
Everything works as intended but in some case I get the following error:

I have no idea if its an issue from my side but I was wondering if somebody else had this issue before.

And not related but also a bit bothersome is that in regular monitors (1920x1080) the gui screen does not work because the run button does not fit. I run it with the config files so it does not affect me but I thought that it was worth mentioning.

Hi,

Regarding your first question, yes, we have seen a similar issue in the past, but we could never reproduce it on a different machine.
It would be great if you could share/or privately send me the problematic image. Unfortunately, so far, we have never been able to pinpoint the issue.

Regarding your second question, you should be able to resolve this issue by adjusting the font size in the edit menu. The plantseg gui has been removed from plantsegv2, but we are diligently working on a new one with improved support for different monitors. The new gui is expected to be ready in a few weeks.

Hey @PauCasanova do you still need help for the first part of this issue connected components: Need more labels than can be represented in the destination type.?

For the second part "in regular monitors (1920x1080) the gui screen does not work", please refer to the troubleshooting and issue #241

I just noticed that this issue is related to:

• GASP error: connected components: Need more labels than can be represented in the destination type. #166

Hey @PauCasanova we would really appreciate if you can send us the image for debugging.

Hi there, I already sent an image to Lorenzo Cerrone on the [image: Attachments]3 Oct 2024, 12:58. But here you have it again: https://drive.google.com/file/d/10b44hT2ZnhB-vk4p4rZX__es8PqCg7Om/view?usp=sharing Best, Pau
