No Charts on Visualizations

JoãoFRF

Hey there everyone.
I just started using rapidminer, as I am using it in my university.
I'm here asking for help (I tried figuring it out with my teacher but no success), where I have no graphic what so ever on results -> visualizations.
Here is the print: imgur.com/TTcFYBd.png

Here is the neofetch of my system: imgur.com/he6Hcwn.png


I've tried using the legacy options and the html 5.

Thank you all in advance.

Hi,

I'm actually using the Amazon Coretto Java VM 8 for Studio on Linux nowadays. It is also compatible with the new database connection dialogs.

With OpenJDK, I see:
- Upon start, the Cloud extension can't be loaded
- No visualizations
- Editing database connections doesn't work

Errors in the terminal:
Exception in thread "AWT-EventQueue-1" java.lang.UnsatisfiedLinkError: /home/barany/.RapidMiner/internal cache/browser7.3-ANY/libawt_helper.so: libjawt.so: Can't open shared object file: no such file or directory

Exception in thread "AWT-EventQueue-1" java.lang.NoClassDefFoundError: javafx/beans/property/StringProperty
       at com.rapidminer.connection.gui.model.ConnectionModelConverter.fromConnection(ConnectionModelConverter.java:77)
       at com.rapidminer.connection.gui.AbstractConnectionGUI.<init>(AbstractConnectionGUI.java:132)
       at com.rapidminer.extension.jdbc.connection.gui.JDBCConnectionGUI.<init>(JDBCConnectionGUI.java:40)

So I guess we can only recommend the Coretto JDK for RapidMiner Studio on Linux.

Balázs

hi @JoãoFRF can you please share your rapidminer-studio.log file?

Here it is : pastebin.com/raw/7h3ppz02

thanks @JoãoFRF. That helps. What's your computer hardware and operating system?

@sgenzer
I posted it on the question, I'm using mx linux, on a laptop, i7-7700hq and a 1050ti (no nvidia drivers installed because last time i installed them i had issues (it has conflicts with other softwares i use atm), but i have no need to install them anyways.)

sgenzer

yes that is what I suspected. We are aware of some issues with the visualizations on some Linux installations. Our resident Linux expert is @BalazsBarany so I will see if he has any insight here. Otherwise you may wish to use RapidMiner on any standard Windows / Mac machine.

@sgenzer
But it is the only feature that doesn't work, everything else seems alright, graphics work etc, just not in the visualizations tab

sgenzer

Yup. That's exactly what we have heard from time to time. Let's see what Balazs has to say.

BTW, this is the download link: https://docs.aws.amazon.com/corretto/latest/corretto-8-ug/downloads-list.html

@BalazsBarany
And now how do I "force" rapidminer to use that java version?

BalazsBarany

Hi,

I set JAVA_HOME before calling RapidMiner. You can also put the following into your RapidMiner-Studio.sh at the beginning:

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-amazon-corretto

Worked like a charm.
Thank you so much!

JoãoFRF

In any case someone ends ups here with the same problem here's what I did.
As i'm in a debian based distro after getting told to use the amazon correto 8 I did this:

sudo dpkg --install java-1.8.0-amazon-corretto-jdk_8.242.07-1_amd64.deb

I downloaded the file here: docs.aws.amazon.com/corretto/latest/corretto-8-ug/downloads-list.html

sudo update-alternatives --config java

selected the number with the correct version and restarted rapidminer.

Thanks @JoãoFRF for sharing the installation process.

I've heard from developers that the problem is only temporary, affecting version 9.5.
Studio 9.6 will also work with OpenJDK again, as it will bundle the necessary libraries.
