Common Causes of Python Errors in QGIS Plugins

1. Missing or incompatible dependencies

2. Plugin not compatible with your QGIS version

3. Corrupted plugin installation

4. Python path issues or environment conflicts

Step-by-Step Troubleshooting

1. Read the Full Error Message

• Open QGIS

• Go to Plugins → Python Console → Show Traceback or check the Log Messages Panel (View → Panels → Log Messages) for details.

Please share the full error message here if you'd like help interpreting it.

2. Check QGIS Version Compatibility

• Go to Plugins → Manage and Install Plugins

• Find Animation Workbench

• Check if it says "This plugin is not compatible with your version of QGIS."

You may need to:

• Update QGIS (use the latest LTR version)

• Or install an older plugin version compatible with your QGIS

3. Remove and Reinstall Plugin

Sometimes a clean reinstall fixes weird bugs.

To remove:

~/.local/share/QGIS/QGIS3/profiles/default/python/plugins/animation_workbench 

Delete the plugin folder, then reinstall it from the Plugin Manager.

4. Install Missing Dependencies

If the error mentions modules like matplotlib, numpy, etc.:

On Windows (OSGeo4W Shell):

python3 -m pip install matplotlib numpy

On Linux/macOS:
Make sure to use the same Python environment QGIS uses.

5. Check Python Version in QGIS

In QGIS Python Console:

import sys print(sys.version) 

Then confirm that the plugin supports that version of Python.
