I get this error when I use the Generalized Linear Model operator.

 

  • Exception: java.lang.RuntimeException
  • Message: Invalid ice_root: C:/Users/Guilherme Passero/.RapidMiner/H2O/, Illegal character in path at index 18: C:/Users/Guilherme Passero/.RapidMiner/H2O/

If I run it again, I get a different error message:

Can anyone help me?

 

EDIT: I'm using RapidMiner Studio Free v7.6.000 at Windows 10.

    hi @gpassero - yes you can't have a white space in a filename path (between Guiherme and Passero).  I'm a UNIX/Mac guy so can't give you the solution...maybe a Windows person will chime in?  :)

    I forgot to mention that I haven't had this problem until the last update.

    I upgrade as well and the processes that worked yesterday no longer do, with the same cloud error you reported. I tried remove the white spaces from my process and repository names, but no luck. RM is now dead in the water.

    FYI, I rolled back to 7.5.001 and no more errors occur. There is a definately a bug in v7.6.

    Same problem here. All the H20 operators give this error.

    OK thanks all.  I am passing this along to the dev team right now and will keep you posted.  Meanwhile yes rolling back to 7.5 may be a good idea.

    Hi,

     

    Thank you for the report, and sorry for the inconvenience.

     

    Besides the downgrade, the only workaround with 7.6 currently is to use a different folder as a user home folder that does not contain whitespaces. This can be achieved by adding a line to RapidMiner-Studio.bat like this:

    set _JAVA_OPTIONS="-Duser.home=c:/rmhome"

    where rmhome is a directory that exists and the user can write into. If the .RapidMiner folder is copied into this new folder, your settings should be unaffected.

     

    Edit: with the 7.6.0 version, the workaround is to specify the following option with a similar path in RapidMiner-Studio.bat (instead of the empty _JAVA_OPTIONS value):

    set _JAVA_OPTIONS="-Dai.h2o.ice_root=c:/tmp_ice_root/"

    where tmp_ice_root is a directory that exists and the user can write into (it can be a different path that does not contain whitespaces). This should prevent the error when running using these operators.

     

    Best,

    Peter

    Hi All,

     

    again, thank you for the bug report and your patience.

     

    I am happy to say you should no longer have this problem with the 7.6.1 release.

    Best,
