I tried doing the Image Classification Process - Got stuck when running the "Compute Confusion Matrix" after generating Random Points for Accuracy Assessment for Image Classification.
I am getting a message as below.
WARNING 001790: Not all points have valid class values.
ERROR 001094: Invalid file extension. The "" file extension is used for an ArcGIS dataset.
ERROR 999999: Error executing function.
Failed to execute (ComputeConfusionMatrix).
