Hi everyone,
the project file still contains the relative link to the training image. Maybe your edit was not accepted?
Without a change to the ilastik project, it executes infinitely in Knime. The node cannot be reset, either.
Anyhow, from the error message Fritz posted I don't think it's actually related to the dimensionality of the image.

When I try to reproduce, I get a different error:
ERROR Ilastik Headless (Pixel classification) 0:2 Error when executing Ilastik. Please check the dimensionality of the input images. DEBUG Ilastik Headless (Pixel classification) 0:2 reset ERROR Ilastik Headless (Pixel classification) 0:2 Execute failed: Unable to delete file: D:\TEMP\ilastik\e0c877fe-846a-4359-a97f-2d35307187d0\file0_result.tif DEBUG Ilastik Headless (Pixel classification) 0:2 Execute failed: Unable to delete file: D:\TEMP\ilastik\e0c877fe-846a-4359-a97f-2d35307187d0\file0_result.tif java.io.IOException: Unable to delete file: D:\TEMP\ilastik\e0c877fe-846a-4359-a97f-2d35307187d0\file0_result.tif at org.apache.commons.io.FileUtils.forceDelete(FileUtils.java:2279)
In summary, that makes three different problems.
