[SOLVED] Rapidminer\scripts not working in 5.3?

Am I the only one seeing errors with the scripts in 5.3?  If I try to execute any of the files in the scripts directory on 5.3, I get the error: 
RAPIDMINER_HOME is not set. Trying the directory 'C:\Program Files\Rapid-I\Rapid Miner5\scripts\..'...
Using local jre: C:\Program Files\Rapid-I\RapidMiner5\scripts\..\jre\bin\java.exe...
Starting RapidMiner from 'C:\Program Files\Rapid-I\RapidMiner5\scripts\..' using classes from 'C:\Program Files\Rapid-I\RapidMiner5\scripts\..\lib\rapidminer.jar'...
Creating file "\\check_rm_java_version"
The filename, directory name, or volume label syntax is incorrect.
The problem seems to be the line in the .bat files that says: 

set CHECK_VERSION_FILE="%HOMEPATH%\check_rm_java_version"
At least on my machine, HOMEPATH=\, so this ends up putting doubled slashes in the file create, which fails.  Correcting that problem leads to this: 
Usage: com.rapidminer.RapidMinerCommandLine [-f] PROCESS [-Mname=value]
  PROCESS       a repository location containing a process
  -f            interpret PROCESS as a file rather than a repository location (deprecated)
  -Mname=value  sets the macro 'name' with the value 'value'
It appears that the new build of CommandLine insists on getting a PROCESS passed in.   Without thoroughly testing it, it does appear that the script will work if you pass in a valid process path.

    Hi,

    which script have you started? The rapidminer.bat or the RapidMinerGUI.bat script? The rapidminer.bat script should be used to run RapidMiner as a command line tool. Run the RapidMinerGUI.bat script if you want to run RapidMiner in GUI mode.

    We assumed that %HOMEPATH% would reference to the users folder. Please replace %HOMEPATH% by some directory you may write to. This is needed to determine which Java
    version you are running to select the correct garbage collector.

    Best,
    Nils

    Both scripts are broken.
    We assumed that %HOMEPATH% would reference to the users folder.
    That assumption is correct.  But on Windows, %HOMEPATH% ends in a backslash, e.g., 
    HOMEPATH=\
    So the way you use %HOMEPATH% in the scripts will cause an error.  You should instead write this: 
    set CHECK_VERSION_FILE="%HOMEPATH%check_rm_java_version"
    without the backslash between %HOMEPATH% and check_rm_java_version.

    Any comment on the problem with com.rapidminer.RapidMinerCommandLine requiring a process file?  Have you tried running either of the scripts on a Windows machine under 5.3?  Do they work for you?

    Another script problem:  If you try to start RapidMinerGUI.exe with a process argument on Windows, it hangs with the splash screen showing "Creating Frame" and the following error in the command window:

    Strange, my %HOMEPATH% variable does not end with a backslash. For me 'echo %HOMEPATH%' outputs '\User\NAME'.
    Wikipedia and other pages also  state that the %HOMEPATH% variable does not  end with a backslash (http://en.wikipedia.org/wiki/Environment_variable, http://environmentvariables.org/HomePath).
    Because this will be the case most of the time we won't change the script here. If it is not working for you, please remove the backslash and it should work afterwards.

    Yes the scripts work for me. To start the RapidMiner GUI just call RapidMinerGUI.bat from within the scirpts folder without any more parameters.
    If you want to run a process without the GUI, run rapidminer.bat and provide the correct paramters.

    Best,

    Also fixed the error when starting RapidMinerGUI.bat with a process argument. With the next release 5.3.1 you can run the RapidMinerGUI.bat script like this: 

    RapidMinerGUI.bat //Repository/path/to/object

    Fair enough.  It looks like our Windows machines here are set up incorrectly wrt HOMEPATH. 

    In another thread, Marius pointed out that starting the scripts in the scripts directory without setting RAPIDMINER_HOME wouldn't work, and that might also be the source of some of my problems.  My suggestion would be that the RapidMiner installation on Windows set the RAPIDMINER_HOME environment variable.

    Otherwise, I think you've addressed all my issues, so I'll mark this solved.  Thanks for your patience!

    On Windows you can start RapidMiner without setting RAPIDMINER_HOME if you start it from within the scripts folder. But setting RAPIDMINER_HOME when installing the .exe is a good idea.
    I've opened an internal issue for that.

    Thanks,
    Nils

    Let me re-open this topic momentarily.

    Some investigation suggests that %HOMEPATH% can be legitimately set to "\" (or something similar) in Windows.  For example, see this discussion:

    http://serverfault.com/questions/85713/when-would-the-windows-environment-variable-be-homepath

    I can't find any direct discussion of it on Microsoft's tech support, but it's at least mentioned in this discussion:

    http://support.microsoft.com/kb/236813

    under the Windows 2000 section.  It seems that when a user's home directory is on a shared server, you can end up with HOMEPATH=\.

    I believe the correct solution is to use %USERPROFILE% instead of %HOMEPATH%.  So in the script files you would say:

    set CHECK_VERSION_FILE="%USERPROFILE%\check_rm_java_version"

    This should be more reliable than what you're currently doing.

    If you do continue to use %HOMEPATH% you should really use %HOMEDRIVE% as well, since your scripts will likely fail for someone whose HOMEDRIVE is not the current drive of the shell running the script.

    Hi again,

    thanks for these valuable information. With this findings we probably should change the environment variable.
    And having a closer look I think %APPDATA% is the best and savest choice to make.
    Would you be so kind to test if it also works on your environment?

    Best,
    Nils

    %APPDATA% would work on my machine.  %TEMP% or %TMP% would probably be reasonable choices as well.
  • Nils_Woehler
    Nils_Woehler New Altair Community Member
    You're right, this would also make sense. But I think we will stick with %APPDATA% for now.

    Best,
    Nils
