Overview

QA test script for validating ensemble model pipeline execution in the Triton Inference Server.

Description

This test validates the Triton Inference Server's ensemble model scheduling, which allows chaining multiple models into a single inference pipeline. It verifies that ensemble models correctly route tensors between component models according to the ensemble configuration, that input and output tensor mappings are properly resolved, and that the final ensemble output matches expected results. The test covers linear pipelines, fan-out and fan-in topologies, and validates error handling when individual ensemble steps fail.

Usage

Run as part of the Triton QA test suite. Requires a GPU-enabled Docker environment with pre-generated test models.
