I am trying to execute Build your Chat Bot with Dolly Demo using my own VM. At the first steps they are executing this command 

%run ./_resources/00-init $catalog=hive_metastore $db=dbdemos_llm
 

which is -as I understand- calling another python script to set some environment variables. Now I have to include these scripts in my environment. But I am facing a problem with dbutils they are using. what is it exactly? and how to include it into my code?
