description TVM Overview

TVM (Apache TVM) is an open-source compiler framework for deep learning systems. It automatically optimizes deep learning models for various hardware platforms, including CPUs, GPUs, and specialized accelerators. TVM's goal is to enable efficient deployment of deep learning models across a wide range of devices, from cloud servers to embedded systems. It focuses on hardware-agnostic optimization and deployment.

help TVM FAQ

What is Apache TVM actually used for?

TVM is an open-source compiler stack, hosted by the Apache Software Foundation, that optimizes deep learning models to run efficiently on CPUs, GPUs, and specialized accelerators. Its goal is letting you deploy a single trained model across very different hardware targets without hand-tuning kernels.

How does TVM differ from TensorRT or ONNX Runtime?

TVM is a compiler that generates and tunes kernels for many hardware targets, whereas NVIDIA's TensorRT is optimized specifically for NVIDIA hardware. ONNX Runtime is more of an inference runtime, while TVM compiles and optimizes the computation itself for whatever backend you target.

What are AutoTVM and Ansor in TVM?

They are TVM's automatic tuning systems, which search for the fastest kernel schedules on your specific hardware instead of relying on hand-written implementations. Ansor, introduced through research around 2020, improved on AutoTVM by generating search spaces automatically.

Which model formats can I bring into TVM?

TVM has frontends for common formats such as ONNX and TFLite, plus paths from frameworks like PyTorch and TensorFlow. After import, it compiles the graph down to optimized target code, which is especially useful for edge and embedded deployment.
