RapidMiner Studio Hangs on Launch "Initializing Plugin GUI"
Learner IIIRapidMiner Studio 8.2 on MacOS 10.13.4
When I launch RapidMiner Studio, the program starts to load, but hangs on the step "Initializing Plugin GUI" and wont finish loading. If I disable "Initialize Extensions" the the program will load, but obviously it will not have any extensions, including "Auto Model". What is the root cause of this problem and how can I solve it beyond just disabling "Initialize Extentions"? It does not seem to be related to any individual extension as if I disable all of them in the extension manager, it doesn't solve this problem.

hi @tim_davis - seems that one extension is causing the problem. You can enable / disable them one by one in the Extensions --> Manage Extensions" menu. I'd try there.
Scott
That is not the problem. I deleted all the extension I could in the manage extension dialog and that did not resolve the issue. I mentioned this in my initial post.
oops sorry @tim_davis my error. In that case I would recommend making a backup copy of your .RapidMiner folder and then empty the folder completely out. When you restart RapidMiner, it will make fresh versions of all those files.
Scott
What is the normal path to this directory? I can't seem to find it.
Hi @tim_davis,
the .RapidMiner folder is (by default) stored at the following location :
C:\Users\Username

I deleted the directory /Users/"username"/.RapidMiner, but that does not seem to have changed the situation at all. The behavior was exactly the same the next time I tried to launch RapidMiner Studio, and the directory was recreated during that launch.
ok I'm starting to see what's going on here. You're starting this from the CL so that's already unusual. And the hang is not on an extension - that's all default stuff. Can you please send your rapidminer-studio.log file to me via PM?
Scott
Hi, did you solve the problem? If yes, please share the solution. I have the same problem.

thank you. I have to mention that I had been using Rapidminer 8.X and it just worke fine, till I update to 9.1. Now it takes ages for RapidMiner to start. Here is the log file. Thank you very much for your feedback.
You mentioned that RapidMiner might not have been properly installed. I simply uninstalled RapidMiner and furthermore deleted the .Rapidimer folder. This was not clever, because I had some custom pipelines which I lost. But anyway, afterward, I installed RapidMiner (9.1) again.
After the fresh installation (yes the problem persists):
1. I run windows 10 (64bit).
2. There is no managed folder, and the extensions folder only contains a "workspace" folder which however seems to be empty.
3. In the installation directory (lib folder) there are 83 jar-files. the first starts with activation-1.1.jar to and the last is xstream-1.4.10.jar. There are also 2 sub folders in the lib folder (plugins and jdbc). The plugin folder has got 17 jar files (beginning with cloud_connectivity-9.0.0-all.jar to time_series-9.1.0-all.jar ) in it. The jdbc subfolder has got 11 jar files (beginning with commons-logging-1.1.3.jar to ucanaccess-3.0.4.jar) in it.
I observed a different aspect which might be weird. During the start up process RapidMiner hangs up as describes above (or it takes several minutes to start). During the startup prcess, it displayes several extensions (for example time series abalysis) which I apparently installed. Please see the enclosced screen shot.
However, if I try to disable or to uninstall these extensions, RapidMiner tells me that no extensions are installed.
It is true that I had used the time series extension in version 8.X before I updated to 9.1. It seems that 9.1 inherits this information from somewhere, although the .RapidMiner folder had been deleted.
At the moment RapidMiner is so slow that I cannot work with it. For example, even drag and dropping of sample data takes several seconds. It is hardly possible to build more elaborated pipelines. So in this sense, your help is very much appreciated since I have several assignments to read where students have used RapidMiner.
Is there a chance to downgrade to 8.X? This version seems to just work fine.
Thanky you.
Best

rapidminer.studio.deny.allcommunication=trueIf this speeds up your start-up time, we need to investigate which connections are blocking your startup.I followed carefully your instructions and I came to the following results.
1. After RapidMiner has startet I do not see the "Training Resources" and "Community Samples" in my repository view.
2. I added rapidminer.studio.deny.allcommunication=true to the rapidminer-studio-settings.cfg file. I just added it at the end of the file. It looks now like:
But it did not seem to speed up the starting process, although I had the impression that it positively influenced the performance one RapidMiner has started.
3. I thought you are right about that a different application blocks rapidminer (I particularly suspected my windows defender firewall) (Windows 10)). Consequently, I had a look and found that rapidminer is allowed to connect to the web from private and public networks.
Unfortunately, this did not positively influence the problem.
4. I checked f-secure (this is my virus scanning program). It has the option to disable all security features. And........then rapidminer starts as quickly as possible. So far, great. But it is not an option to have everything (firewall, scanning on viruses etc.) disabled.
Maybe you have another tip (like opening a port or so) to keep f-secure running.
Thank you very very much, your help is very much appreciated.

Do you have a browser-general.log file in your .RapidMiner/internal cache/browser7.4-OSX/ folder?
Regards,
Marco
You are using OpenJDK 14 for running RapidMiner Studio. Is there any possibility for you to install Java 8? Some internals are not yet translated to newer versions of Java (most if not all of these are third party libraries included by RapidMiner Studio to work). You can install Java 8 alongside Java 14, therefore this shouldn't be a problem.
All the best,
Rod.
However, the situation did not change.
Hi Marco,
Unfortunately, the file you mentioned doesn't seem to exist.
Satoshi
You could try two things:
- If you have not already done so, please try and simply restart your Mac. Not sleep but a full restart.
- Delete the .RapidMiner/internal cache folder and start Studio again.
There seems to be a problem of getting the Chromium browser running, for whatever reason. And without a browser log file being created, it's a bit of poking in the dark unfortunatelyRegards,
Marco
