Deprecated Deadline 7 Bug Reports
#1

Hi there

we have a problem with the latest Deadline beta with Houdini 14.0.395.

This is the error that can be found in the logs.

Now I have found out that there is a script which is copied to the rendernodes home folder in /home/<deadline_username>/Thinkbox/Deadline7/slave/<rendernode_hostname>/plugins/<some_gibberish_(job_id?)>/Houdini.py
in which you guys state that if( houdiniExe == “” ) houdiniExe should be assigned a value. The thing is houdiniExe doesn’t exist before you compare it with an empty string. I think that simply adding houdiniExe = “” before the if or removing the if should fix this. So if this is truly the problem I would like to know from where this script is copied to the home folder so I can change this. I was unable to find it in the repository.

All best,
Damjan

Hey Damjan,

Thanks for reporting this! We actually discovered this issue last week, and it will be fixed in beta 4.

Cheers,
Ryan

Can you please tell me if the fix I mentioned is plausible and if it is point me to the file so I can make the change in order to have a working Houdini setup until the new beta release?

#4

The fix is to simply add the houdiniExe = “” line above the “if SystemUtils.IsRunningOnWindows():” check in the RenderExecutable function. Here’s what that function should look like after:

    def RenderExecutable( self ):
        version = self.GetPluginInfoEntryWithDefault( "Version", "14" )
        build = self.GetPluginInfoEntryWithDefault( "Build", "none" ).lower()
        houdiniExeList = self.GetConfigEntry( "Houdini" + version + "_Hython_Executable" )
        
        if( SystemUtils.IsRunningOnLinux() ):
            houdiniExeList = houdiniExeList.replace( "hython", "hython-bin" )
        
        houdiniExe = ""
        if SystemUtils.IsRunningOnWindows():
            if( build == "32bit" ):
                self.LogInfo( "Enforcing 32 bit build" )
                houdiniExe = FileUtils.SearchFileListFor32Bit( houdiniExeList )
                if( houdiniExe == "" ):
                    self.LogWarning( "Houdini " + version + " hython 32 bit executable was not found in the semicolon separated list \"" + houdiniExeList + "\". Checking for any executable that exists instead." )
            elif( build == "64bit" ):
                self.LogInfo( "Enforcing 64 bit build" )
                houdiniExe = FileUtils.SearchFileListFor64Bit( houdiniExeList )
                if( houdiniExe == "" ):
                    self.LogWarning( "Houdini " + version + " hython 64 bit executable was not found in the semicolon separated list \"" + houdiniExeList + "\". Checking for any executable that exists instead." )
            
        if( houdiniExe == "" ):
            houdiniExe = FileUtils.SearchFileList( houdiniExeList );
            if( houdiniExe == "" ):
                self.FailRender( "Houdini " + version + " hython executable was not found in the semicolon separated list \"" + houdiniExeList + "\". The path to the render executable can be configured from the Plugin Configuration in the Deadline Monitor." )
        
        if( SystemUtils.IsRunningOnLinux() ):
            houdiniExe = houdiniExe.replace( "hython-bin", "hython" )
        
        return houdiniExe

The file you want to modify is Houdini.py, and it can be found in \your\repository\plugins\Houdini.

Hope that helps!

Thanks Ryan, that did the trick!
