Visualization is not working at all

Shourya

Hello,

I am using the most recent version of Rapidminer studio in Ubuntu 18.04

After importing a CSV file, I wanted to make some visualizations and after importing and connecting to the output I press the run process button on the top. Then when I go to visualizations I get only blank screens. Please help.

I tried a new beta version and ultimately it worked without changing anything.

It seems you have the wrong version of Java installed on your system - probably too new, e.g. Java 10. Carefully read the "Prerequisites" section of the installation instructions for RapidMiner and see what Java version you must have on your system - at the moment it must be Java 8.

Hi,

What does the ~/.RapidMiner/rapidminer-studio.log file say?

Regards,

＠Shourya, It is worth checking what＠Marco_Boeckis suggesting.

However, I had exactly the same problem on my Ubuntu 18.04 and could not get rid of it, until I installed Oracle Java 8 (not a default OpenJDK. Also make sure that it is Oracle Java 8 which used as a default on your system. Try the following:

$ java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

$ sudo update-alternatives --config java
[sudo] password for jacob: xxxx
There are 3 choices for the alternative java (providing /usr/bin/java).

Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-11-openjdk-amd64/bin/java 1111 auto mode
1 /usr/lib/jvm/java-11-openjdk-amd64/bin/java 1111 manual mode
2 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1081 manual mode
* 3 /usr/lib/jvm/java-8-oracle/jre/bin/java 1081 manual mode

Press to keep the current choice[*], or type selection number:

At this point you will be able to select Java which works with RapidMiner. In my case, this solved the problem.
