Re: HELLO WORLD GA EXAMPLE

[zaleslaw]

Sorry for the long delay, I missed your answer
Please, play with examples located here
https://github.com/apache/ignite/tree/master/examples/src/main/java/org/apache/ignite/examples/ml

For example, you could get
https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/ml/knn/KNNClassificationExample.java
or
https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/ml/regression/logistic/binary/LogisticRegressionSGDTrainerExample.java

Please run and write about results here or in separate thread

After installing the files ignite-ml and ignite-rest-http from the optional
folder in /libs inside IGNITE_HOME folder please tell me if i missed any
files to put in /lib... I will try some of the other examples lol ;) I ran
the Hello-World example again and got the following error:

Re: HELLO WORLD GA EXAMPLE

[zaleslaw]

Dear @AlphaMufasaOmega could you please run another ML examples like
KNNRegression example or LogisticRegression in ml-examples.

Could you post the result here or in separate thread? Will it be the same
problem or not?

Re: HELLO WORLD GA EXAMPLE

[Ilya Kasnacheev]

Hello!

GA examples are standalone as far as my understanding goes. You don't need
to launch Ignite node explicitly. Can you try killing it and restarting the
example?

Otherwise, as it tells you, enable peer-class-loading or add ML jars to
libs/

Re: HELLO WORLD GA EXAMPLE

[AlphaMufasaOmega]

I did end up getting a node started by running the following command:

user@PTFAssaultMachine:~/apache-ignite-fabric-2.6.0-bin$ bin/ignite.sh
/home/user/apache-ignite-fabric-2.6.0-bin/examples/config/example-ignite.xml

This started  a node.. I then followed the instructions as provided in the
Hello World example found here:

https://apacheignite.readme.io/docs/genetic-algorithms <<-by title
Apache Zeppelin Integration

and ran the following command in another terminal with a node,zeppelin
already started in different terminal windows:

user@PTFAssaultMachine:~/apache-ignite-fabric-2.6.0-bin/examples$ sudo mvn
exec:java
-Dexec.mainClass="org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample"
 

This results in a strange situation where zeppelin works but doesn't show
the tables as in the Hello World
example(https://apacheignite.readme.io/docs/genetic-algorithms) we get a
strange stack from the apache ignite node:

Re: HELLO WORLD GA EXAMPLE

Dear techbysample,

   there is no example-config.xml the only files that are in tat folder are
example-ignite.xml, example-default.xml, example data-regions.xml, and
example-chache. Which one of these .xml files should I use? I am running
this in a debian-9 virtual machine inside qubes4.0 Linux, after running the
command that you recommended I get the follow stack:

This was the error I had before that I ran into... I change IGNITE_HOME to
the absolute path of the Direcotry and still got the following error stack:

Re: HELLO WORLD GA EXAMPLE

[techbysample]

AlphaMufasaOmega ,

Hello.  How many nodes are running?  Did you remember to start at least one

standalone Ignite node BEFORE running the HelloWorld GA Example?

I suspect from your logs that the node has stopped.  That is why Zeppelin
cannot connect

to Ignite.

Type the following to start a stand alone node PRIOR to running HelloWorld
GA Example :

 bin/ignite.sh IGNITE_HOME/examples/config/example-config.xml

As a result,  the HelloWorld GA node will stop, but you will have one Ignite
node standing.
I verified and was able to see the results in Apache Zeppelin as shown
below.




 


Best,

Turik
