Hey in the prefect 2.0 docs it says

Copy code

All tasks must be called from within a flow. Tasks may not call other tasks directly.

Does this mean we can't call task.run() like in 1.0? That was quite useful...

Further to this, I'm reading the tutorial getting started docs here https://docs.prefect.io/tutorials/execution/ And on this page a task is called with a

.submit

out of nowhere and with no explanation as to what its doing and why. Maybe worth adding some explanation?

Well there is mention lower down...

Copy code

Call .submit on the task instead of calling the task directly. This submits the task to the task runner rather than running the task in-process.

You may lose some if you don't mention it earlier in the document though.

There’s also

task.fn()

which calls the underlying function (which I think is equivalent to task.run() if I’m not mistaken)

@Ben Muller You’re right. Thanks for the feedback. We will add more description on

.submit
