Base constructor.

Each object requires:

• a GraphQL client - in order to fill its missing members dynamically
• an initial data blob - typically from unserialized JSON, contains at
• least the data for required members (typically the object's primary key) and optionally other data members.

Status of pipeline

Returns a list of the steps of a pipeline. Not exactly a shim

Returns a list of the model configs of a pipeline. Not exactly a shim

Remove a step at a given index

Perform inference with a single model.

Replaces the step at the given index with a model step

Perform inference on the same input data for any number of models.

Replaces the step at the index with a multi model step

Run audit logging on a specified slice of model outputs.

The slice must be in python-like format. start:, start:end, and :end are supported.

Replaces the step at the index with an audit step

Select only the model output with the given index from an array of outputs.

Replaces the step at the index with a select step

Split traffic based on the value at a given meta_key in the input data, routing to the appropriate model.

If the resulting value is a key in options, the corresponding model is used. Otherwise, the default model is used for inference.

Replace the step at the index with a key split step

Routes inputs to a single model, randomly chosen from the list of weighted options.

Each model receives inputs that are approximately proportional to the weight it is assigned. For example, with two models having weights 1 and 1, each will receive roughly equal amounts of inference inputs. If the weights were changed to 1 and 2, the models would receive roughly 33% and 66% respectively instead.

When choosing the model to use, a random number between 0.0 and 1.0 is generated. The weighted inputs are mapped to that range, and the random input is then used to select the model to use. For example, for the two-models equal-weight case, a random key of 0.4 would route to the first model. 0.6 would route to the second.

To support consistent assignment to a model, a hash_key can be specified. This must be between 0.0 and 1.0. The value at this key, when present in the input data, will be used instead of a random number for model selection.

Replace the step at the index with a random split step

Create a "shadow deployment" experiment pipeline. The champion model and all challengers are run for each input. The result data for all models is logged, but the output of the champion is the only result returned.

This is particularly useful for "burn-in" testing a new model with real world data without displacing the currently proven model.

This is currently implemented as three steps: A multi model step, an audit step, and a select step. To remove or replace this step, you need to remove or replace all three. You can remove steps using pipeline.remove_step

Replace a given step with a shadow deployment

Add a dict of validations to run on every row.

Remove all steps from the pipeline. This might be desireable if replacing models, for example.

List the explainability configs we've created.

Get the details of an explainability config.

Create a shap config to be used later for reference and adhoc requests.

Create a new version of a pipeline and publish it.

Creates a new PipelineVersion and stores it in the database.
