v1.4.2

• kd.ckpts:

  • [New] SimpleCheckpointLoader: A new loader to load parameters and
    collections directly as-is without path maps or non-OSS model surgery. Also
    supports conditionally loading the optimizer state (load_opt_state=True).

• kd.konfig:

  • [New] Add support for the | (PEP 604) union operator on lazy config
    object proxies (e.g. MyClass | None).
  • [New] Add __or__ (|) operator to ConfigDict to cleanly merge copies
    of configurations.

• kd.klinen:

  • [Removed] Remove the deprecated kauldron.klinen module.

• kd.data:

  • [Fix] Fix ElementWiseRandomTransform breaking deterministic randomness
    in PyGrain pipelines by avoiding RNG pool spawning.

• kd.metrics:

  • [Fix] Cast boolean metric values to float32 in Accuracy to prevent
    array overflow in dense per-pixel tasks.

• kd.ktyping:

  • [Changed] Disable dimension deletion and restrict assignments
    (kt.dim["a"] = 7) to only allow adding new dimensions.

• kd.cli:

  • [New] Add run estimate_hbm subcommand to estimate GPU memory usage.
