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.

XML-code

<参数键= value =“csv_file /用户/ Frosteryd/Google Drive/UU ��/Informationsutvinning I, 5.0 hp/Lab-1/iris_data.csv"/>





<参数键= " skip_comments " value = " false " / >

























<参数键= value =“csv_file /用户/ Frosteryd/Google Drive/UU ��/Informationsutvinning I, 5.0 hp/Lab-1/iris_labels.csv"/>





<参数键= " skip_comments " value = " false " / >














































































<参数键= value =“csv_file /用户/ Frosteryd/Google Drive/UU ��/Informationsutvinning I, 5.0 hp/Lab-1/iris_unseen.csv"/>





<参数键= " skip_comments " value = " false " / >































<连接from_op =“Sample”from_port = "例output" to_op="Sort" to_port="example set input"/>

ok@Linus_FrosterydI 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:

<参数键= value =“csv_file /用户/ 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 hintshere.

@sgenzerThanks! 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!
