Overview

Taichi (太极) is a parallel programming language for high-performance numerical computations. It is embedded in Python, and its just-in-time compiler offloads compute-intensive tasks to multi-core CPUs and massively parallel GPUs.

Advanced features of Taichi include spatially sparse computing, differentiable programming [examples], and quantized computation.

Please check out our SIGGRAPH 2020 course on Taichi basics: YouTube, Bilibili, slides (pdf).

Installation

Official releases

python3 -m pip install taichi

Supported OS: Windows, Linux, Mac OS X; Python: 3.6-3.9 (64-bit only); Backends: x64 CPUs, CUDA, Apple Metal, Vulkan, OpenGL Compute Shaders.

Nightly releases

Nightly releases with the master branch of taichi are also available:

pip install -i https://test.pypi.org/simple/ taichi-nightly

Note nightly releases are bleeding edge versions and thus may and will contain bugs. Those releases are primarily aimed for alpha feature testing. If you need a stable version, please refer to the official release above.

Building from source

Please build from source for other configurations (e.g., your CPU is ARM, or you want to try out our experimental C backend).

Note:

• The PyPI package supports x64 CPU, CUDA 10/11, Metal, Vulkan and OpenGL Compute Shader backends.
• On Windows, please install Microsoft Visual C++ Redistributable if you haven't.
• [All releases]
