Error in Change Detection plugin (could not execute GRASS script changedetection.py)

[coreysnipes]

How did you install WebODM (docker, installer, etc.)?

Windows installer - v 2.0.3

What's your browser and operating system? (Copy/paste the output of https://www.whatismybrowser.com/)

firefox 116 on Win 10

What is the problem?

Change detection plugin does not execute. Dependency issue? The error output is limited in the UI:

Could not execute GRASS script C:\WebODM\resources\app\apps\WebODM\coreplugins\changedetection\changedetection.py 
from C:\WebODM\resources\app\data\media\tmp\tmplddbrnxa_grass_engine:

When I try to blindly execute the script directly in powershell I show a missing module 'rasterio':

PS C:\WebODM\resources\app\apps\WebODM\coreplugins\changedetection> python .\changedetection.py
Traceback (most recent call last):
  File ".\changedetection.py", line 111, in <module>
    from compare import compare
  File "C:\WebODM\resources\app\apps\WebODM\coreplugins\changedetection\compare.py", line 1, in <module>
    import rasterio as rio
ModuleNotFoundError: No module named 'rasterio'

How can we reproduce this? (What steps trigger the problem? What parameters are you using for processing? Include screenshots. If you are having issues processing a dataset, you must include a copy of your dataset uploaded on Dropbox, Google Drive or https://dronedb.app)

• Create two tasks with DSM+DTM
• Enable change detection plugin
• Attempt to use change detection on one task using default settings
• Observe error

Here are my change detection settings:

Here is the relevant section of app.log:

My python version is 3.7.9

Is this under the latest/current Build?

[coreysnipes]

Hiya; here's the WebODM console output from powershell.

Yes, I believe this is the latest build - 2.0.3 Build 89

Is this all of the log right from when you execute webodm.exe? It looks like a few lines are missing

[coreysnipes]

Oh, sorry. I didn't realize you wanted the full log. Here you go. I do see a message in there about failing to install requirements for changedetection at line 129. Other than that pip version warning I can't see any specific failures though.

I'm guessing it's an issue with the installation of the necessary pip dependencies for the plugin on Windows.

This is no longer applicable as the change detection plugin is now archived. #1435
