How to fix a broken plugin (it cannot import name NavigationToolbar2QTAgg)

Question

I want to use the the pluging ProfileFromPoints but I am getting an error saying cannot import name NavigationToolbar2QTAgg. The solution seems to link with an old library name as mentioned here: https://github.com/semiautomaticgit/SemiAutomaticClassificationPlugin/issues/2

Can I amend it without wayting for the bug fix?

Answer 1

I proceeded with the plugin installation without caring about the warning. Then I wnet to the pluging directory and I manually edited the python file profileFromPoints_dialog.py

In the line 30 I changed:

 39# from matplotlib.backends.backend_qt4agg import NavigationToolbar2QTAgg as NavigationToolbar

to

 39# from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as NavigationToolbar

Then, I restarted QGIS and I needed to load the plugin.
