The number of data labels is 4. the eval loss increase and the train loss decrease. I think it is overfit. Code is as below:

code

from setfit import SetFitModel, Trainer, TrainingArguments, sample_dataset, SetFitModelCardData
import ujson as json
from datasets import load_dataset, DatasetDict, Dataset
from transformers import EarlyStoppingCallback
import datetime

def convert_files_to_dataset(train_path, val_path):
    # 定义一个函数来读取单个文件
    def read_file(file_path):
        with open(file_path, 'r', encoding='utf-8') as f:
            lines = f.readlines()
            data = [json.loads(line.strip()) for line in lines]
        return data

    # 读取训练集和验证集
    train_data = read_file(train_path)
    val_data = read_file(val_path)

    # 将数据转换为Dataset
    train_dataset = Dataset.from_list(train_data)
    val_dataset = Dataset.from_list(val_data)

    # 创建DatasetDict
    dataset_dict = DatasetDict({'train': train_dataset, 'validation': val_dataset})

    return dataset_dict

# 使用函数
train_path = 'train_cn.txt'
val_path = 'val_cn.txt'
dataset = convert_files_to_dataset(train_path, val_path)

from setfit import sample_dataset

train_dataset = sample_dataset(dataset["train"], num_samples=50)
print(train_dataset)

eval_dataset = dataset["validation"]
print(eval_dataset)
from setfit import SetFitModel

model = SetFitModel.from_pretrained('sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2', model_card_data=SetFitModelCardData(
        language=['en', 'de', 'nl'],
    ))
from sentence_transformers.losses import CosineSimilarityLoss

from setfit import SetFitTrainer

trainer = SetFitTrainer(
    model=model,
    train_dataset=train_dataset,
    eval_dataset=eval_dataset,
    loss_class=CosineSimilarityLoss,
    num_iterations=20,
    num_epochs=5
)
trainer.train()
metrics = trainer.evaluate()
print(metrics)```

log is as below:
