ERROR 003436: No training samples found for these classes

[SamiraNorouzi]

Hi all,

I am attempting supervised and object-based image classification using Arch Pro (V.3.2). Here are the steps I have followed:

I acquired Sentinel-2 imagery and combined bands 2, 3, 4, and 8 (10m resolution).
I performed image segmentation.
I created a classification schema.
I generated training samples.
However, when I attempt to classify using a support vector machine classifier, I encounter the following error:

ERROR 003436: No training samples found for these classes: Soil, Water, Impervious, Grass, Tress.
The table was not found. [VAT_Segmented_202407110934456475089_interIndex]
The table was not found. [VAT_Segmented_202407110934456475089_interIndex]
Failed to execute (TrainSupportVectorMachineClassifier).
Failed at Thursday, July 11, 2024 9:44:52 AM (Elapsed Time: 0.22 seconds)

(I have attached a screenshot of the error.)

I have tried several times but haven't been able to identify the cause of this error. Do any of you know what might be causing it?

I didn't mask or clip, and I don't have multipart features. Do you know any other possible solutions?

Tech Support would be your best option now

You have to change the name of the layer in the table of contents to your naming convention. Get the "clip" output default name out of there.
