Problem with EnMAP-Box QGIS Plugin for Classfication

I tried to run the EnMAP-Box QGIS Plugin to classify a raster image using Support Vector Classifier. The tool ran for a few minutes but then it failed to give me the results. Instead, it showed these lines of errors:

Traceback (most recent call last):

ValueError: Found array with 0 sample(s) (shape=(0, 11)) while a minimum of 1 is required by StandardScaler.

Can someone tell me what these errors mean and how could this be avoided? Thanks.
