mindformers.trainer.TranslationTrainer¶

class mindformers.trainer.TranslationTrainer(model_name: Optional[str] = None)[源代码]¶

Translation Task For Trainer. Args:

model_name (str): The model name of Task-Trainer. Default: None

Examples:

>>> from mindformers.trainer import TranslationTrainer
>>> from mindformers import T5ForConditionalGeneration, TranslationTrainer
>>> # follow the instruction in t5 section in the README.md and download wmt16 dataset.
>>> # change the dataset_files path of configs/t5/wmt16_dataset.yaml
>>> trans_trainer = TranslationTrainer(model_name='t5_small')
>>> trans_trainer.train()
>>> model = T5ForConditionalGeneration.from_pretrained('t5_small')
>>> trans_trainer = TranslationTrainer(model_name="t5_small")
>>> res = trans_trainer.predict(input_data="translate the English to Romanian: a good boy!", network=model)
    [{'translation_text': ['hello world']}]

Raises:

NotImplementedError: If train method or evaluate method or predict method not implemented.

predict(config: Optional[Union[dict, MindFormerConfig, ConfigArguments, TrainingArguments]] = None, input_data: Optional[Union[str, list, GeneratorDataset]] = None, network: Optional[Union[Cell, BaseModel]] = None, tokenizer: Optional[BaseTokenizer] = None, **kwargs)[源代码]¶

Executes the predict of the trainer.

Args:

config (Optional[Union[dict, MindFormerConfig, ConfigArguments, TrainingArguments]]):: The task config which is used to configure the dataset, the hyper-parameter, optimizer, etc. It supports config dict or MindFormerConfig or TrainingArguments or ConfigArguments class. Default: None.
input_data (Optional[Union[Tensor, str, list]]): The predict data. It supports 1) a text string to be: translated, 1) a file name where each line is a text to be translated and 3) a generator dataset. Default: None.
network (Optional[Union[Cell, BaseModel]]): The network for trainer.: It supports model name or BaseModel or MindSpore Cell class. Default: None.
tokenizer (Optional[BaseTokenizer]): The tokenizer for tokenizing the input text.: Default: None.

Returns:

A list of prediction.

train(config: Optional[Union[dict, MindFormerConfig, ConfigArguments, TrainingArguments]] = None, network: Optional[Union[Cell, BaseModel]] = None, dataset: Optional[Union[BaseDataset, GeneratorDataset]] = None, wrapper: Optional[TrainOneStepCell] = None, optimizer: Optional[Optimizer] = None, callbacks: Optional[Union[Callback, List[Callback]]] = None, **kwargs)[源代码]¶

Train task for Translation Trainer. This function is used to train or fine-tune the network.

The trainer interface is used to quickly start training for general task. It also allows users to customize the network, optimizer, dataset, wrapper, callback.

Args:

config (Optional[Union[dict, MindFormerConfig, ConfigArguments, TrainingArguments]]):: The task config which is used to configure the dataset, the hyper-parameter, optimizer, etc. It supports config dict or MindFormerConfig or TrainingArguments or ConfigArguments class. Default: None.
network (Optional[Union[Cell, BaseModel]]): The network for trainer.: It supports model name or BaseModel or MindSpore Cell class. Default: None.
dataset (Optional[Union[BaseDataset, GeneratorDataset]]): The training dataset.: It support real dataset path or BaseDateset class or MindSpore Dataset class. Default: None.
optimizer (Optional[Optimizer]): The training network’s optimizer. It support Optimizer class of MindSpore.: Default: None.
wrapper (Optional[TrainOneStepCell]): Wraps the network with the optimizer.: It support TrainOneStepCell class of MindSpore. Default: None.
callbacks (Optional[Union[Callback, List[Callback]]]): The training callback function.: It support CallBack or CallBack List of MindSpore. Default: None.

Raises:

NotImplementedError: If wrapper not implemented.
