<div dir="ltr">Yes, I understand now. I had been following the instructions on <a href="http://yt-project.org/doc/orientation/simple_data_inspection.html">http://yt-project.org/doc/orientation/simple_data_inspection.html</a>, which said the command yt should produce "a number of subcommands". I didn't realize those subcommands were <i>supposed</i> to be a part of an error message. Thanks for the clarification.<div style>

The 'yt' command line interface is a way to quickly examine datasets. As the help prompt you pasted indicates, you need to pair the 'yt' command with a subcommand in order to do anything. For example:</div>

There are a number of other subcommands, you can get more information on them using 'yt --help'.</div>
<div><br></div><div>While yt's command line interface is good for looking quickly at a dataset, it's not so great for in-depth analysis. For that, you'll want to make an ipython notebook or python script using yt's python interface. Here is a brief introduction to using yt from python:</div>
