'NoneType' object is not subscriptable while performing clustering #208

Closed benert007 closed 2 years ago

benert007 commented 2 years ago

Hey everyone.

I have been trying to perform K-means and ISODATA clustering but am not able to, thanks to this 'NoneType' object is not subscriptable error. My QGIS version is currently 3.16 with the SCP version being 7.10.5 - Matera running on Windows 11 OS. I'm attaching a snap of the error message.

Thanks Luca

Thank you @benert007 for the log file. I would suggest to update QGIS.

benert007 commented 2 years ago

I had first used SCP in the latest version of QGIS. And that is where the issue began. So I installed QGIS 3.16, it being the most stable, but the problem persued.

semiautomaticgit commented 2 years ago

Could you please try to use this sample dataset ?

benert007 commented 2 years ago

The sample dataset was classified perfectly. No errors or issues. So I used another dataset that I already had but got the above-mentioned error.

Thank you. What images are you using?

benert007 commented 2 years ago

Landsat 8 and LISS 3 images

semiautomaticgit commented 2 years ago

Possibly it is a memory issue. Please check that there is enough disk space (during the process large temporary files can be created)

benert007 commented 2 years ago

Hi Luca.

I had the images processed in another with more free memory and it worked. Thanks a lot for your help! Talking with you has been awesome!
