Cannot set Repository path to save ...

hi,

I can#t set the correct repository path in store and export process parameter field...

I want to use time macro to create a folder and save them (example set + process) in the same folder ... here is my process:

when I set the store path to "%{Zeit}/NameofExampleSet" it says invalid character "/"

but I can do the same in the export process operator, there it works:

%{Zeit}/Prozess

I can confirm that it works fine in the local repository but it fails when stored in the Cloud repository.

But looking into the stacktrace the reason seems to be the operator from "Information Selection" extension so we (RapidMiner) cannot do anything as it is not maintained by us. You can try to contact the maintainer of the "Information Selection" extension and ask him whether he can fix the bug on his end.

edit: I can only set one of the two, the second operator throws an error then:

EDIT: It only does not work when I set "//Cloud Repository/" as main repository...

with the local ones, it works. Is that a bug or intended?

Fred12

is there a solution to that problem found now?

Nils_Woehler

Hi Fred,

this seems to be a bug in the Cloud repository implementation. Could you please post a minimal process XML which allows to reproduce it on our end?

Thanks!

Nils

ps: What extension is providing the "Export process" operator?

Fred12

the operator is from the "Information Selection" Extension, I originally wanted to store the Experiment "setup" with the settings for different operators, and actually store the process itself in the repository with the settings I made when the process starts...

here is the process:

I can confirm that it works fine in the local repository but it fails when stored in the Cloud repository.

Fred12

ok thanks,

I could try

Fred12

here is the answer that I got:

I’ve checked it and the problem is on RapidMiner side, you can submit a bug to their system.
This problem appears when a new folder in the cloud is created, but only when you use the zeit macro . The system creates the folder, but somehow one of internal RapidMiner functions returns null instead of the new folder name.
The funny thing is that the problem appears only for the first execution. The next time everything works ok, because the folder is being created at the first time so in the following execution the system can save the process.
I’ve also checked that it only appears when the zeit macro is used so it must be related to the macro format.
What I can suggest for now is to use the zeit macro in the file name instead of folder name for example like this:
//Cloud Repository/User/Prozess_%{zeit}
