第9与第10个cell-数据集规整化准备
预处理数据集，对数据集进行规整。规整成第9个cell中样式
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
train_prompt_style = """Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request. Before answering, think carefully about the question and create a step-by-step chain of thoughts to ensure a logical and accurate response.
### Instruction: You are a medical expert with advanced knowledge in clinical reasoning, diagnostics, and treatment planning. Please answer the following medical question.
### Question: {}
### Response: <think> {} </think> {}"""
利用如下第10个cell中如下函数对数据集进行规整，将问题、思维链与回答填充到上述prompt中

第13个cell-Model training
此cell偶尔会出现运行失败的问题，提示【failed to upsert bucket:
returned error 401 Unauthorized: {"errors":[{"message":"user is not

trainer_stats = trainer.train()
此cell正常运行过程中输出如下：

第14个cell-保存微调模型
cell内容无需修改。执行后，输出如果如下。

此时在wandb.ai网站中查看对应project的运行情况，发现状态已经是Finished：
