If you want to use GUI you should run dagit not dagster command `dagit lt some attrs if you like gt ` After this if everything was successful you ll see `Loading repository Serving on <http 127 0 0 1 3000|http 127 0 0 1 3000>`

Hi Kevin I see how the instructions on <https docs dagster io tutorial setup|https docs dagster io tutorial setup> could be clearer here sorry about that the instructions to navigate to localhost in your browser only apply to the third option for executing the pipeline Dagit web UI The other two options execute the pipeline right there in the command line
