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).

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 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.

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]
