cannot load plugin geoscience when calling its classFactory() method #7

Cannot load plugin 'geoscience' due to an error when calling its classFactory() method

I am using QGIS 3.8 but also confirmed on 3.4. Have removed the geoscience folder under python directory and re-installed. Have removed all layers created by the plugin in the active QGIS project and re-installed. None of these attempts rectified the issue.

Here's the error message:

Thank you for your help.

Hi David,

It looks like the plugin is trying to load sections from your QGIS Project file that don't exist. I'm not sure how that has happened. To recover the project and get Geoscience to load again you will need to tell it that there are no sections (or the correct number of sections) to load. You will need to edit the qgs project file. Look for "<Sections " and change it to 0. [image: image.png]

If you see real sections in the project (denoted by the prefix S00, S01 etc) then you can set it to the correct number (eg 1 if you have S00, 2 if you have S00 & S01).

If your project is a qgz, then it is just a zipped qgs. Simply unzip it, edit it then re-zip.

I'll change the code so it doesn't crash if this happens in the future. Thanks for the report.

Regards, Roland

Hi Roland,

Thank you for your reply. It looks like there may have been images in your email but these did not show up. However, I tried to follow the text instructions.

I believe I removed sections in the active project several times through a process of trial and error in testing the plugin (which is useful by the way!) . Here’s what I did:

  1. I searched the qgs version of the file for the string “Sections “ and found:
2 (I tried 0 and 2, originally it had 1 in the file) 2. I searched for S00 (and S01 etc) and find two mentions of S00 but these are obviously two different sections: cxq_100 1 581306 6998304 581149E CollarV1_Corrected_3D CollarV1_Corrected_Desurvey 2 580991 6997776 50 0 1 1 0 0 581149E 0 50 50 2 So it looks like I have managed to create a bit of a mess. Any suggestions? Thanks again.
