XDRL
Hook-first interpretability for TorchRL
xdrl provides typed interaction contracts and TDHook bindings for TorchRL models. TorchRL continues to own trainer execution, logging, evaluation, checkpointing, and environments; xdrl makes model-internal observation and intervention explicit at those interaction boundaries.
Key Features
Typed interaction contracts
Describe model roles, TensorDict schemas, execution phases, and batch semantics without replacing TorchRL’s trainer lifecycle.
TDHook-powered interpretability
Observe and intervene inside declared TorchRL model interactions with TDHook while preserving native TensorDict behaviour.
