"User error operator MCIO (multiple_color_image_opener) cannot be executed"

john1

good afternoon

I have a problem with  my project and i cannot understand why?

my code is :

 

RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
RapidMiner.init();

Process location = new Process(new File("C:\\Users\\john\\.RapidMiner\\repositories\\Local Repository\\processes\\project_solar_parks.rmp"));

Operator a = location.getOperator("MCIO");

a.setPairParameter("images", "photovoltaika", save_image);

IOContainer ioResult = location.run();
IOObject result = ioResult.getElementAt(0);

 

 

and the error is :

com.rapidminer.operator.UserError: The dummy operator MCIO (replacing imageprocessing:multiple_color_image_opener) cannot be executed.
at com.rapidminer.operator.DummyOperator.doWork(DummyOperator.java:94)
at com.rapidminer.operator.Operator.execute(Operator.java:1004)

at com.rapidminer.operator.OperatorChain.doWork(OperatorChain.java:428)
at com.rapidminer.operator.Operator.execute(Operator.java:1004)

 

can someone help me?

 

thanks

This era relates to the fact that the process cannot find the image mining extension. It appears you might be using RapidMiner server? If so you need to install the image mining extension on the server for you to execute a process on the server.

Good afternoon

I am not using RpidMiner Server . I am using RapidMiner version 7.0 Basic Edition.

I plugged in image_miner 1.4.1.jar  Extensions .

This message:

 

"com.rapidminer.operator.UserError: The dummy operator MCIO (replacing imageprocessing:multiple_color_image_opener) cannot be executed.
at com.rapidminer.operator.DummyOperator.doWork(DummyOperator.java:94)"

 

Means that it's not finding the opreator somehow. Did you properly install the extension? The image mining exetension is a 3rd party extension, I would ping @Vaclav to see what your problem could be.

i dowloaded the imageminer from here: http://splab.cz/en/download/software/immi-rapidminer-extenison

i putted the jar into rapidminerstudio/lib/plugin/

after that i putted the same jar in my java project as library

Hello John,

If I understand it properly, you are trying to run RM from code. The problem is, that the plugin is not loaded, because RM has it's own way to load plugins.  You have to set the plugin directory before calling RapidMiner.init();

 

System.setProperty(RapidMiner.PROPERTY_RAPIDMINER_INIT_PLUGINS_LOCATION,"C:/Program Files/RapidMiner/plugins/");
RapidMiner.init();

Hope this helps.

Unfortunately my programm didnot work.

Again print the same mistake.

 

Thomas_Ott

When you run RapidMiner Studio and load your process and hit Play, does it work?

john1

yes 

error message:

 <em class="error">The operator class 'imageprocessing:open_color_image' is unknown. Possibly you must install a plugin for operators of group 'imageprocessing'.</em>

i changed MCIO to open color image the same message appears .

Thomas_Ott

Yeah you did something wrong when you installed the plugin. So until you fix that, it's not going to work. I would try to reinstall it again and follow the image mining documentation on how to do it: http://www.burgsys.com/download/mumi_enterprise.pdf

i do exactly what the pdf says.I notice that when put the jar  rapidminer-Image_1.4.1.jar in my project .i use netbeans.i notice that  print a unexpected exception: org.netbeans.modules.parsing.spi.ParseException

i donot ksno why happens this.

i want to ask you how to say in rapidminer api java that the operator "open color image" refers to the class ReadColorImageOperator 

thanks
