oint name and this method will try to instantiate it using `model_classes`. Since we don't want to instantiate the model twice, this model is returned for use by the pipeline. If both frameworks are installed and available for `model`, PyTorch is selected. Args: model (`str`, [`PreTrainedModel`] or [`TFPreTrainedModel`]): The model to infer the framework from. If `str`, a checkpoint name. The model to infer the framewrok from. model_classes (dictionary `str` to `type`, *optional*): A mapping framework to class. task (`str`): The task defining which pipeline will be returned. model_kwargs: Additional dictionary of keyword arguments passed along to the model's `from_pretrained(..., **model_kwargs)` function. Returns: `Tuple`: A tuple framework, model. rd
