Jeg likte hvordan Gunnar skrev stort sett all koden i farten mens vi gikk gjennom, men at det var rikelig med forhåndsforberedt materiale på google drive som jeg kan referere til etter treningen. Koden Gunnar skrev basert på eksempeldataene jeg ga på forhånd var også svært nyttig og gjorde også opplæringen relevant for våre egne datasett.
