Hi, I'm new to rapidminer. But I get a really dirty error message when I try to open a process that I have saved. It's the same thing if I choose to export and then later import it or save it to the processes folder. I have been loaded som regular CSV files into the processes.

    Solution Accepted

    ok @Linus_Frosteryd I see what's going on.  Yes as you suspected, your Read CSV operator is not liking your filepath due to the &# characters in it.  You can see it in the XML in line 17:

     

    <parameter key="csv_file" value="/Users/Frosteryd/Google Drive/UU &#55357;&#56538;/Informationsutvinning I, 5.0 hp/Lab-1/iris_data.csv"/>

    hello @Linus_Frosteryd - very good to have you here.  I have moved this thread to the Getting Started Forum - our place for questions from new users like yourself.  :)

     

    I'd be happy to help you figure this out.  Can you please repost/edit with your process XML, datasets, etc..?  You can see some helpful hints here.

    @sgenzer Thanks! Newbies like me, need all the help we can get at the beginning! I have updated the post with the XML-code I using some datasets in CSV-format ?

    Great, thanks! Now it works. Had some problem reading my google drive directory properly!
