IREE: Intermediate Representation Execution Environment
IREE (Intermediate Representation Execution Environment,
pronounced as "eerie") is an MLIR-based end-to-end
compiler and runtime that lowers Machine Learning (ML) models to a unified IR
that scales up to meet the needs of the datacenter and down to satisfy the
constraints and special considerations of mobile and edge deployments.
See our website for project details, user
guides, and instructions on building from source.
