Hi, I am trying to apply Decision Tree learner on a large data set about 20000X30000- (rows by columns), however it errors out with - “Execute failed: java heap space” error.
Current configuration of machine- 8 GB Ram
Knime.INI file- -Xmx4032m
4 GB RAM is not that much. You could try to give 5 or 6 leaving 2 for the system. Then you might want to explore these collection about performance issues and what go to about them:
Hi @thampy123 and welcome to the KNIME community forum
@mlauber71 is right about the need of extra memory but I’m also wondering about the underlying nature of the problem you need to solve.
Could you please tell us a bit about it ? What kind of problem do you need to solve ? Where do the 30,000 variables come from and why so many ?
Knowing a bit more about your data should help us to guide you further.
