'NoneType' object has no attribute 'log'

[urograndis]

Good morning. I am running QGIS 3.38.0-Grenoble on a 64-bit platform, Ubuntu 22.04.4 LTS. I had the Semi-Automatic Classification Plugin installed and was running the Region Growing Algorithm when it crashed and closed. When I restarted, I got the message: Semi-Automatic Classification Plugin: 'NoneType' object has no attribute 'log'. I uninstalled and reinstalled the plugin: Plugin installed successfully; But it doesn't even appear in the taskbar and the message: 2024-07-30T09:29:41 WARNING Semi-Automatic Classification Plugin: 'NoneType' object has no attribute 'log' 2024-07-30T09:29:42 INFO Plugin installed successfully. So, I need your help.

Hello @urograndis , it seems an installation issue. Please update the plugin and Remotior Sensus following these installation steps https://semiautomaticclassificationmanual.readthedocs.io/en/latest/installation.html

Hello @urograndis , please update the SCP to version 8.3 and report if you still get the same error

Hello Luca, unfortunately i got the same issue using:

• QGIS 3.38.0
• macOS Sonoma 14.6.1
• SCP 8.3
• remotior-sensus 0.4

works partially on the QGIS-LTR

• Classification Preview works
• Classification itself doesn't

Hello Luca. Same issue here. No chance to enable "Records detailed events in a log file" in the plugin due to it failing to load. Running QGIS 3.38 in Ubuntu 24.04 and SCP 8.3. I get this error: "Semi-Automatic Classification Plugin: 'NoneType' object has no attribute 'log'" Thank you in advance. Your plugin is great for teaching purposes.

Thank you for your feedback. Unfortunately I can't reproduce the issue. I think it is related to the system, or the QGIS Python environment. I suggest to perform a clean installation for example with a new user, or installing through Conda as described here https://semiautomaticclassificationmanual.readthedocs.io/en/latest/installation_conda.html

You're right Luca. It works in Debian 12, tried on a different machine. It's an Ubuntu isuue
