Hi @Jhc,

can you please make sure that Python Scripting 9.7.0 is listed as an installed extension on the AI Hub web interface? (System Information -> Extensions)
An earlier version is likely to cause the error.

Thanks,
Peter

EDIT: Correction: the page to check is Administration -> Operators & Extensions -> Extensions tab.

Hi @Jhc ,

did you restarted the server after the extension upgrade. Until the web UI didn't show the right version, this issue will appear. You should put/replace the extension jar file in the rapidminer-home folder/volume (resources/extensions subfolder) and do a rapidminer-server container restart.

Hi @Jhc ,

in our proposed docker-compose-based deployment the rapidminer-home content is stored on a docker volume. You can easily copy your extension.jar file from your host to the RapidMiner Server's docker comainter into its /rapidminer-home folder using the following docker CLI command: docker cp something.jar containerID:/rapidminer-home/resources/extensions/

You can check the container id using the "docker ps" command or even better you can grep for the rapidminer-server name (in the docker image), so "docker ps | grep rapidminer-server".

Hi,
Thanks for reporting.  @aschaferdiek could this be related to the repository location type changes in 9.7?  We will look into this for sure.
Best,
Ingo

Hi, this could be the case but as far as I know the process is getting executed normally and not within a WebService. Maybe something related to the python extension. I'll ping @phellinger.

Thank you @phellinger.

when i checked the python scripting version, it was version 9.6.
the extension version was updated to 9.7, but it is still version 9.6 on the server. 

isnt't it automatically linked with the server?
to change python scripting to 9.7, do we have to work on it separately??

Hi @ZSzatmari,
 
We used docker to deploy a RapidMiner Server.

I tried to put the extension jar file in the rapidminer-home folder but could not fine the rapidminer-home folder.

When i install RapidMiner using docker, where can i find the rapidminer-home folder??
