Need Help Using STORE Operator, Getting Error Message

NS9

Hello,

I'm trying to use the Store operator to store my model, just like the deprecated "Write Model" operator, so I can retrieve it in a different portion of the process. When I attempt to use the Store operator I get the following messages in my log.

Feb 24, 2021 9:38:49 AM WARNING: File reading error.

Feb 24, 2021 9:38:49 AM WARNING: Loading script failed from: with error java.io.IOException: (The filename, directory name, or volume label syntax is incorrect)

Below is my XML process. Please let me know if there's anything else needed to help me solve this issue.

Hi,

Store expects a Repository location, not a disc location.

Best,

Martin

Hello mschmitz,

How can I create a repository location that is not on my local hard drive?

BalazsBarany

Hi @NS9,

you can create a new repository on a shared drive/folder in your company, or use an AI Hub repository. 
Select the "Show repository actions" button in the Repository panel to add a new repository. It would be a "local" repository for the shared folder option (even if it is on a remote computer), or an AI Hub repository.

What problem are you trying to solve? Would you like to share your results (e. g. the model) with outer people using RapidMiner? Then both ways mentioned would work.
Another way for this scenario is to use Git projects, either integrated into RapidMiner ("Connect to a Git project") or with external versioning using a different tool. 

Regards,

Balázs

Thank you Balazs,

I got it working somehow. all I did was create a new folder in my local repository and for some reason it allowed me to save it there.

Kind regards,

NS
