That function is declared to need an argument.

Except:

>     cloud.generate_from_frequencies()

you call it without an argument.

Further, it looks like it was actually a method in a class, because of
the way you call it - but there is no class definition in what you
included, so we can't really untangle this for you completely.  Even
stranger, a thing called file_contents is referenced _outside_ the
function, which isn't going to work

However the error is pretty clear:

> TypeError: generate_from_frequencies() missing 1 required positional
> argument: 'frequencies'

you needed to call it with an argument and you didn't.
