Forest-based Classification and Regression missing Explanatory Training Rasters input space

[EmmaZHatcher]

I'm trying to use the Forest-based Classification and Regression to potentially use for a model instead of Google Earth Engine. In all of the tutorials & documentation, it appears there should be an Explanatory Training Rasters input option when you select 'Predict to raster' as your Prediction Type. I just upgraded to 2.9 last week and ran the most recent patch, and the tool just doesn't have that as an input, which in tutorials and other pictures appears below the 'Treat Variable as Categorical' checkbox. I attempted to use the Python version of the tool, and got a general, uninformative error. Anyone else run into this problem?

Hello Emma,

Do you have the Spatial Analyst extension licensed on your ArcGIS Pro machine? This is because the help doc (link below) states that:

• An ArcGIS Spatial Analyst extension license is required to use rasters as explanatory variables or to predict to an Output Prediction Surface value.

You are right- that's the problem! I missed that since the tool appeared accessible... sneaky. Thank you!
