Transformers x SwanLab：可视化NLP模型训练_swanlabcallback如何不打印日志信息

HuggingFace 的 Transformers 是目前最流行的深度学习训框架之一（100k+ Star），现在主流的大语言模型（LLaMa系列、Qwen系列、ChatGLM系列等）、自然语言处理模型（Bert系列）等，都在使用Transformers来进行预训练、微调和推理。

SwanLab是一个深度学习实验管理与训练可视化工具，由西安电子科技大学团队打造，融合了Weights & Biases与Tensorboard的特点，能够方便地进行 训练可视化、多实验对比、超参数记录、大型实验管理和团队协作，并支持用网页链接的方式分享你的实验。

你可以使用Transformers快速进行模型训练，同时使用SwanLab进行实验跟踪与可视化。
下面将用一个Bert训练，来介绍如何将Transformers与SwanLab配合起来：

1. 代码中引入SwanLabCallback

from swanlab.integration.huggingface import SwanLabCallback
1

SwanLabCallback是适配于Transformers的日志记录类。

SwanLabCallback可以定义的参数有：

• project、experiment_name、description 等与 swanlab.init 效果一致的参数, 用于SwanLab项目的初始化。
• 你也可以在外部通过swanlab.init创建项目，集成会将实验记录到你在外部创建的项目中。

2. 传入Trainer

from swanlab.integration.huggingface import SwanLabCallback
from transformers import Trainer, TrainingArguments
...

# 实例化SwanLabCallback
swanlab_callback = SwanLabCallback()

trainer = Trainer(
    ...
    # 传入callbacks参数
    callbacks=[swanlab_callback],
)

3. 案例-Bert训练

查看在线实验过程：BERT-SwanLab

下面是一个基于Transformers框架，使用BERT模型在imdb数据集上做微调，同时用SwanLab进行可视化的案例代码

"""
用预训练的Bert模型微调IMDB数据集，并使用SwanLabCallback回调函数将结果上传到SwanLab。
IMDB数据集的1是positive，0是negative。
