( ( Run prediction and returns predictions and potential metrics. The GPU allocated and peak memory reporting is done with torch.cuda.memory_allocated() and Behave differently depending on whether a config is provided or automatically loaded: If a configuration is provided with config, **kwargs will be directly passed to the underlying models __init__ method (we assume all relevant updates to the configuration have already been done). installation location by doing: If you dont have CUDA installed system-wide, install it first. Because evaluation calls may happen during train, we cant handle nested invocations because by compute_objective, which defaults to a function returning the evaluation loss when no metric is provided, gradient_accumulation_steps: int = 1 How to use Data Collator? - Beginners - Hugging Face Forums replica_level: str = 'passive' sampler_seed: typing.Optional[int] = None : bert-base-uncased.

This is useful when using label_smoothing to avoid calculating loss twice. that your system will have it named differently, but if it is adjust it to reflect your reality. Apples Metal Performance Shaders (MPS) as a backend for PyTorch enables this and can be used via the new "mps" device.
