Apache TVM is a compiler stack for deep learning systems. It is designed to close the gap between theproductivity-focused deep learning frameworks and the performance- and efficiency-focused hardware backends.TVM works with deep learning frameworks to provide end-to-end compilation for different backends.

TVM is licensed under theApache-2.0 license.

Check out theTVM Documentation site for installation instructions, tutorials, examples, and more.TheGetting Started with TVM tutorial is a greatplace to start.

TVM adopts the Apache committer model. We aim to create an open-source project maintained and owned by the community.Check out theContributor Guide.

TVM started as a research project for deep learning compilation.The first version of the project benefited a lot from the following projects:

• Halide: Part of TVM's TIR and arithmetic simplification moduleoriginates from Halide. We also learned and adapted some parts of the lowering pipeline from Halide.
• Loopy: use of integer set analysis and its loop transformation primitives.
• Theano: the design inspiration of symbolic scan operator for recurrence.

Since then, the project has gone through several rounds of redesigns.The current design is also drastically different from the initial design, following thedevelopment trend of the ML compiler community.

The most recent version focuses on a cross-level design with TensorIR as the tensor-level representationand Relax as the graph-level representation and Python-first transformations.The project's current design goal is to make the ML compiler accessible by enabling mosttransformations to be customizable in Python and bringing a cross-level representation that can jointlyoptimize computational graphs, tensor programs, and libraries. The project is also a foundationinfra for building Python-first vertical compilers for domains, such as LLMs.
