I am currently facing this issue whenever I submit my scene to deadline.
Error: Houdini 17_5 hython executable was not found in the semicolon separated list "C:\Program Files\Side Effects Software\Houdini 17.5.229\bin\Hython.exe;/Applications/Houdini/Houdini17.5.229/Frameworks/Houdini.framework/Versions/Current/Resources/bin/hython;/opt/hfs17.5/bin/hython". The path to the render executable can be configured from the Plugin Configuration in the Deadline Monitor. at Deadline.Plugins.PluginWrapper.RenderTasks(String taskId, Int32 startFrame, Int32 endFrame, String& outMessage, AbortLevel& abortLevel)
