Hi Team,

In QGIS, installed Supervised Classifier plugin for my image classification problem statement.
[cid:7c049d98-b193-4a7f-ae7f-aa581c098e59]
[cid:22e90dbc-ea0f-4873-838e-f52727d05a57]
As I thought this plugin would be plug n play but encountered 2 issues:


  1.
After installing the plugin, got issue with opening of ClassificationDialogBox
supervised_classifier.py", line 549, in show_classification_dialog               self.dialog = ClassificationDialog()               ^^^^^^^^^^^^^^^^^^^^              NameError: name 'ClassificationDialog' is not defined
Resolution: Added an import statement at the top of the file
  2.
During execution, I encountered lot of indentation errors as I opened the supervised_classifier.py file notepad++, fixed this in the entire file.


I have checked the QGIS-Developer Issues Archive website and above issues were not available. Hence am writing to the team to have a look and also would be helpful to know if there are any changes in my steps.

Thanks,
Deepti
