TiRexForecaster

class TiRexForecaster(model='NX-AI/TiRex', device: str = 'cpu', license_accepted: bool = False)[source]

Interface to the TiRex Zero-Shot Forecaster.

This forecaster loads the TiRex model from the tirex-ts package when fit() is called. Instead of training, it takes the given data as context, and predict() uses that context to produce forecasts for the requested future time points. torch is required at runtime and a clear error is raised if unavailable.

Parameters:

modelstr (default = “NX-AI/TiRex”): “Model identifier to load via the vendored TiRex loader”
device{“cpu”, “cuda”, …}, default=”cpu”: Compute device used by the underlying TiRex model.
license_acceptedbool, default=False: Whether the user accepts the license terms of TiRex. Must be set to True to use the model.

Attributes:

model_object: The loaded TiRex model instance (vendored implementation).
