Review comment:
As it also support http:// and gs:// I would prefer calling it from_url.
Note: from can not be used.

> The Python SDK does not currently stage its user-defined functions or
> dependencies when talking to the job API. Artifacts that need to be staged
> include the user code itself, any SDK components not included in the
> container image, and the list of Python packages that must be installed at
> runtime.
>
> Artifacts that are currently expected can be found in the harness boot code:
