QGIS 3.0 - "ModuleNotFoundError: No module named 'tkinter' "

[Dan-Knott]

Hi team,

The tuflow plugin doesn't appear to be working in QGIS 3.0.3. Just wondering if anyone else has been having this issue.

Error message:

Couldn't load plugin 'tuflow' due to an error when calling its classFactory() method

Hi Dan, are you installing QGIS 3 through osgeo4w or through the stand-alone installer?

[Dan-Knott]

Through the stand-alone installer

[TUFLOW-Support]

Just to narrow down what is causing the problem, does it error when you type the following into the QGIS 3 python console?

import matplotlib.pyplot as plt

[Dan-Knott]

yeah that throws an error:

I think I've resolved my issue. I had a freshly installed computer to test it out on and found that the issue is being caused by an interaction with another plugin: "Data Analysis and Visualization" https://bitbucket.org/iaborsi/dataexplorer/src

The 'tuflow' crash only happens when QGIS is restarted after installing/enabling this plugin.

While it's an easy fix to just turn off the other plugin, there might be a few more out there that will cause the same issue.

Thanks Dan. It's definitely not ideal that this is happening. I'll try correct this.

Cheers, Ellis.

Hey Dan, just to let you know I've now fixed this and the fix will be included in the next plugin release :)
