Make Long-Running NVIDIA TensorRT Engine Builds Observable and Cancelable in Python or C++

NVIDIA TensorRT’s IProgressMonitor API lets developers track and cancel long‑running engine builds in both Python and C++. By overriding phase_start, step_complete, and phase_finish, the monitor reports nested progress to terminals, IDEs, or HTTP services while remaining thread‑safe and responsive to user or programmatic stop requests. A minimal drop‑in implementation shows how to integrate progress reporting and graceful cancellation, preventing wasted GPU‑hours during extended builds.
