Error 999999 with Export Training Data for Deep Learning

[cGISs]

Hello, I've been attempting to use Export Training Data for Deep Learning, with an Input Raster of a TIFF file and an Input Feature Class consisting of traced vector lines, and have consistently received Error 999999. I'm trying to produce Labeled Tiles, and each of my vectors is labeled with a Class value of 1. I have tried the following measures:

1. Change the output folder location so that the character count of the path is under 128 characters
2. Reduced the Processing Extent in Environment to a fraction of what is was originally
3. Decrease the Tile and Stride Size (tile size was originally 2048 to match size of training data of original model, but when decreased to 256 it still doesn't work)
4. Tried with my project and all the associated files in my local C drive.

Any ideas on what else I can do? Any advice would be greatly appreciated.

• What is the geometry type of your input features — are they polylines or have you tried converting them to polygons?
• Do the raster and features share the same coordinate system?
