🦖 Turkish LM Tuner

Overview

Turkish LM Tuner is a library for fine-tuning Turkish language models on various NLP tasks. It is built on top of Hugging Face Transformers library. It supports finetuning with conditional generation and sequence classification tasks. The library is designed to be modular and extensible. It is easy to add new tasks and models. The library also provides data loaders for various Turkish NLP datasets.

Installation

You can install turkish-lm-tuner via PyPI:

pip install turkish-lm-tuner

Alternatively, you can use the following command to install the library:

Examples

Fine-tune and evaluate a conditional generation model

from turkish_lm_tuner import DatasetProcessor, TrainerForConditionalGeneration

dataset_name = "tr_news"
task = "summarization"
task_format="conditional_generation"
model_name = "boun-tabi-LMG/TURNA"
max_input_length = 764
max_target_length = 128
dataset_processor = DatasetProcessor(
    dataset_name=dataset_name, task=task, task_format=task_format, task_mode='',
    tokenizer_name=model_name, max_input_length=max_input_length, max_target_length=max_target_length
)

train_dataset = dataset_processor.load_and_preprocess_data(split='train')
eval_dataset = dataset_processor.load_and_preprocess_data(split='validation')
test_dataset = dataset_processor.load_and_preprocess_data(split="test")

training_params = {
    'num_train_epochs': 10,
    'per_device_train_batch_size': 4,
    'per_device_eval_batch_size': 4,
    'output_dir': './', 
    'evaluation_strategy': 'epoch',
    'save_strategy': 'epoch',
    'predict_with_generate': True    
}
optimizer_params = {
    'optimizer_type': 'adafactor',
    'scheduler': False,
}

model_trainer = TrainerForConditionalGeneration(
    model_name=model_name, task=task,
    optimizer_params=optimizer_params,
    training_params=training_params,
    model_save_path="turna_summarization_tr_news",
    max_input_length=max_input_length,
    max_target_length=max_target_length, 
    postprocess_fn=dataset_processor.dataset.postprocess_data
)

trainer, model = model_trainer.train_and_evaluate(train_dataset, eval_dataset, test_dataset)

model.save_pretrained(model_save_path)
dataset_processor.tokenizer.save_pretrained(model_save_path)

Evaluate a conditional generation model with custom generation config

from turkish_lm_tuner import DatasetProcessor, EvaluatorForConditionalGeneration

dataset_name = "tr_news"
task = "summarization"
task_format="conditional_generation"
model_name = "boun-tabi-LMG/TURNA"
task_mode = ''
max_input_length = 764
max_target_length = 128
dataset_processor = DatasetProcessor(
    dataset_name, task, task_format, task_mode,
    model_name, max_input_length, max_target_length
)

test_dataset = dataset_processor.load_and_preprocess_data(split="test")

test_params = {
    'per_device_eval_batch_size': 4
}

model_path = "turna_tr_news_summarization"
generation_params = {
    'num_beams': 4,
    'length_penalty': 2.0,
    'no_repeat_ngram_size': 3,
    'early_stopping': True,
    'max_length': 128,
    'min_length': 30,
}
evaluator = EvaluatorForConditionalGeneration(
    model_path, model_name, task, max_input_length, max_target_length, test_params,
    generation_params, dataset_processor.dataset.postprocess_data
)
results = evaluator.evaluate_model(test_dataset)
print(results)
