I think the problem is not that the .ilp file can not be found by KNIME. The error message refers to the ilastik executable. If you want to use ilastik headless node in a workflow you have to point KNIME first to the path where you’ve installed ilastik. In your case it should be the path of
ilastik-1.1.8-win64.exe. You can find these settings in the KNIME preferences. I’ve attached a picture.
Best,
