Dec 1, 2024December 2024: DeepInv (deepinv/deepinv) delivered a critical dependency upgrade and diffeomorphism support to simplify installation, improve reproducibility, and enable advanced transform capabilities. Replaced the direct libcpab dependency with a PyPI-installable variant to support diffeomorphisms, random number generators (RNGs), and device handling for transforms. Updated testing procedures and packaging configurations to reflect the dependency change, reducing build fragility and CI-related issues. This work lays groundwork for broader geometric-transform support and more robust production deployments.
