Anipose lib

An easy-to-use library for calibrating cameras and triangulation in Python.

This is the backend library for the Anipose package.

aniposelib-pytorch

This branch is published on PyPI as aniposelib-pytorch: the PyTorch/GPU version of aniposelib (cameras are torch.nn.Modules, GPU-batched triangulation and bundle adjustment). It still imports as aniposelib.

pip install aniposelib-pytorch

Install torch with the CUDA build that matches your GPU first if you need a specific one (see https://pytorch.org/get-started/locally/).

It cannot be installed alongside classic aniposelib (numpy, 0.8.x) because both provide the aniposelib import. aniposelib-pytorch depends on a file-less placeholder aniposelib==0.0.1, so pip/uv refuse environments that also require classic aniposelib. Replace any aniposelib requirement in your project with aniposelib-pytorch. If both somehow end up installed, import aniposelib raises an error; fix it with:

pip uninstall -y aniposelib aniposelib-pytorch && pip install aniposelib-pytorch

Do not pip install aniposelib==0.8.x into an environment with aniposelib-pytorch: it overwrites the package files. Classic aniposelib is still available with pip install aniposelib in a separate environment.

The documentation is located in Anipose repository.
