how to use rapid miner with c # per command line

rodriguezestefa

Hi, sorry, I'm new to this, I need help.
 I try to use a rapid miner process saved in a local repository, I've seen this code in some question:

 ProcessStartInfo Info = new ProcessStartInfo("C:/Program Files/Rapid-I/RapidMiner/scripts/rapidminer.bat");
            Info.UseShellExecute = false;
            Info.ErrorDialog = false;
            Info.CreateNoWindow = true;
            Info.RedirectStandardOutput = true;
            Info.Arguments = "C:/Program Files/Rapid-I/RapidMiner/scripts/01_ParameterOptimization.xml";
     
            Process p = System.Diagnostics.Process.Start(Info); 

            System.IO.StreamReader oReader2 = p.StandardOutput;
            string sRes = oReader2.ReadToEnd();
            oReader2.Close();
            //All the external programs output is now in sRes 
                         
            Console.WriteLine(sRes);
            Console.ReadLine();

Where do I pass the repository route to execute the process? 
How do I send the new excel file from which I want to obtain results based on the training set already done?,

Hi,

I don't know any specifics for the C# interface but basic command line interface for RapidMiner works as follows:

Either from the repository: (here for example via sh command for linux):​

• sh ./programs/rapidminer-studio/scripts/rapidminer-batch.sh ​"//Local Repository/demo"​

The "//" indicates the start of a RapidMiner repository path​​

Or directly pointing to an process file (xml/rmp):​

• sh ./programs/rapidminer-studio/scripts/rapidminer-batch.sh ​-f "/home/demo.rmp"​

In addition you can set macro values by adding -M as parameter, directly followed by the macro name. For example:

• sh ./programs/rapidminer-studio/scripts/rapidminer-batch.sh "//Local Repository/demo" -Msample_size=100 

I hope that helps you.

Best,
David
