Endpoint
Endpoint Examples
Examples of using the Endpoint class are listed at the bottom of this page Examples.
Endpoint: Manages AWS Endpoint creation and deployment. Endpoints are automatically set up and provisioned for deployment into AWS. Endpoints can be viewed in the AWS Sagemaker interfaces or in the SageWorks Dashboard UI, which provides additional model details and performance metrics

Examples
Run Inference on an Endpoint
from sageworks.api.feature_set import FeatureSet
from sageworks.api.model import Model
from sageworks.api.endpoint import Endpoint
# Grab an existing Endpoint
endpoint = Endpoint("abalone-regression-end")
# SageWorks has full ML Pipeline provenance, so we can backtrack the inputs,
# get a DataFrame of data (not used for training) and run inference
model = Model(endpoint.get_input())
fs = FeatureSet(model.get_input())
athena_table = fs.view("training").table
df = fs.query(f"SELECT * FROM {athena_table} where training = FALSE")
# Run inference/predictions on the Endpoint
results_df = endpoint.inference(df)
# Run inference/predictions and capture the results
results_df = endpoint.inference(df, capture=True)
# Run inference/predictions using the FeatureSet evaluation data
results_df = endpoint.auto_inference(capture=True)

The details() method
The detail()
method on the Endpoint class provides a lot of useful information. All of the SageWorks classes have a details()
method try it out!
from sageworks.api.endpoint import Endpoint
from pprint import pprint
# Get Endpoint and print out it's details
endpoint = Endpoint("abalone-regression-end")
pprint(endpoint.details())
Output

SageWorks UI
Running these few lines of code creates and deploys an AWS Endpoint. The Endpoint artifacts can be viewed in the Sagemaker Console/Notebook interfaces or in the SageWorks Dashboard UI. SageWorks will monitor the endpoint, plot invocations, latencies, and tracks error metrics.
