How to run Rapidminer Process from Java console application?

nom1010

I built a process in Rapidminer Studio (classification with decision tree/neural net), I would like to load this process and run it with different datasets in a Java console application. I read about this here, but I didn't really found a great tutorial/documentation, how to do this, the basic things (load process, change properties, change the training model, ... ). Any advice would be helpful.

Thanks! These informations were really helpful.

 

 

RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE); 
RapidMiner.init(); 
Process process = new Process(new File("/MyProcessFile.rmp"));
System.out.println(process.run());

 

 Finally I wrote this, after that I got the result. Maybe it'll be useful for others.

Your best bet is to use RapidMiner Server or getting an OEM license.

@Thomas_Ott that's not right.As long as it part of the open core you can do this. I think there is no explicit documentation on it though.

 

Easy way might be to use the CLI.

 

Best,

Yes, I'd like a simple cli, to load the process and run the process, but I don't really know, how to load a process that I made in Rapidminer, and things like that.

Hi,

 

rm already has an CLI. Just go for 

rapidminer -f myfile.rmp

or

rapidminer //Local Repository/folder/myprocess

.

That works. You can also provide macros if you want to.

 

Best,

Martin
