temporian.save

save(
    fn: Callable[..., Dict[str, EventSetOrNode]],
    path: str,
    *args: Union[EventSetNode, EventSet, Schema],
    **kwargs: Union[EventSetNode, EventSet, Schema]
) -> None

Saves a compiled Temporian function to a file.

The saved function must only take EventSetOrNodes as arguments, return a dictionary of names to EventSetOrNodes, and be decorated with @tp.compile.

Temporian saves the graph built between the function's input and output nodes, not the function itself. Any arbitrary code that is executed in the function will not be ran when loading it back up and executing it.

If you need to save a function that additionally takes other types of arguments, try using functools.partial to create a new function that takes only EventSetNodes, and save that instead. Note that the partial function needs to be compiled too, with tp.compile(partial(...)).

Parameters:

Name	Type	Description	Default
fn	Callable[..., Dict[str, EventSetOrNode]]	The function to save.	required
path	str	The path to save the function to.	required
args	Union[EventSetNode, EventSet, Schema]	Positional arguments to pass to the function to trace it. The arguments can be either EventSets, EventSetNodes, or raw Schemas. In all cases, the values will be converted to EventSetNodes before being passed to the function to trace it.	()
kwargs	Union[EventSetNode, EventSet, Schema]	Keyword arguments to pass to the function to trace it. Same restrictions as for args.	{}

Raises:

Type	Description
ValueError	If the received function is not compiled.
ValueError	If any of the received inputs is not of the specified types.
ValueError	If the function doesn't return the specified type.
