Returns:

The creation time of the model.

drop(failIfMissing: bool = False) → Series[Any]

Drop the model.

Parameters:

failIfMissing – If True, an error is thrown if the model does not exist. If False, no error is thrown.

Returns:

The result of the drop operation.

exists() → bool

Check whether the model exists.

Returns:

True if the model exists, False otherwise.

graph_schema() → Series[Any]

Get the graph schema of the model.

Returns:

The graph schema of the model.

link_features() → list[LinkFeature]

Get the link features of the pipeline.

Returns:

A list of LinkFeatures of the pipeline.

loaded() → bool

Check whether the model is loaded in memory.

Returns:

True if the model is loaded in memory, False otherwise.

metrics() → Series[Any]

Get the metrics for the pipeline model.

Returns:

The metrics for the pipeline model.

model_info() → dict[str, Any]

Get the model info of the model.

Returns:

The model info of the model.

name() → str

Get the name of the model.

Returns:

The name of the model.

node_property_steps() → list[NodePropertyStep]

Get the node property steps for the pipeline model.

Returns:

The node property steps for the pipeline model.

predict_mutate(G: Graph, **config: Any) → Series[Any]

Predict on the given graph using the model and mutate the graph with the results.

Parameters:

• G – The graph to predict on.

• **config – The config for the prediction.

Returns:

The result of mutate operation.

predict_mutate_estimate(G: Graph, **config: Any) → Series[Any]

Estimate the memory needed to predict on the given graph using the model.

Parameters:
