Hello Harijs,
For the out of memory problem, I cannot really help. Maybe @cudroiu ?
But for the test with s2-only, I can help :). I don’t know if you did it already, but we had to modify the crop_type.R script which comes at the end of the crop type process, because of problems encountered using the updated packages. A new crop_type.R script is available here : No predicted classes created in L4A processor, last post.
Can you replace the old /usr/bin/crop_type.R by this one?
Then, can you retry to launch the L4A process with s2-only?
Sorry for the inconvenience.
Philippe
