Classification erosion - semi-automatic classification plugin

Question

I get an error when working Classification Erosion tool in Semi-automatic Classification Plugin (SCP). I use QGIS v3.2.2 and SCP v6.2.4.

The tool is not changing the pixels of the raster layer and creates this short report:

**An error has occurred while executing Python code:**
*NameError: name 'd' is not defined 
Traceback (most recent call last):
  File "C:/Users/Sergio/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\maininterface\erosionTab.py", line 65, in erosionClassificationAction
    self.erosionClassification()
  File "C:/Users/Sergio/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\maininterface\erosionTab.py", line 81, in erosionClassification
    sN = cfg.osSCP.path.basename(str(d))
NameError: name 'd' is not defined*

Classification before erosion:

Answer 1

Variable d doesn't exist and sN is not used anywhere within the file. So, changing that line into comment avoid you to get that error.

I'm not sure if it works but try these:

1. Open erosionTab.py file in any editor. (C:/Users/Sergio/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\maininterface\erosionTab.py)
2. Go to line 81 (sN=cfg.osSCP.path.basename(str(d)))
3. Change to comment by adding hash # to beginning of the line. (#sN=cfg.osSCP.path.basename(str(d)))
4. Save the file, re-open QGIS and try to run SCP again.
