使用官方脚本对应数据集提示列名不匹配，使用同格式自定义数据集报错

[LumenScope]

执行脚本：qwen1_5_14b_chat_qlora_alpaca_e3
数据集：tatsu-lab/alpaca

获取数据集到本地的代码：

from datasets import load_dataset
import json

# 载入数据集
dataset = load_dataset("tatsu-lab/alpaca")

# 假设我们只处理训练集部分
data = dataset['train']

# 将数据保存为 JSONL 文件
with open('/home/tangshi/TangShi/Pku政务大模型/Trainer/Tools/xtuner/data/alpaca_train.jsonl', 'w', encoding='utf-8') as f:
    for item in data:
        json_line = json.dumps(item)  # 将字典转换为 JSON 字符串
        f.write(json_line + '\n')  # 写入文件并添加换行符

获取到的JSONL样例展示：

{"instruction": "Give three tips for staying healthy.", "input": "", "output": "1.Eat a balanced diet and make sure to include plenty of fruits and vegetables. \n2. Exercise regularly to keep your body active and strong. \n3. Get enough sleep and maintain a consistent sleep schedule.", "text": "Below is an instruction that describes a task. Write a response that appropriately completes the request.\n\n### Instruction:\nGive three tips for staying healthy.\n\n### Response:\n1.Eat a balanced diet and make sure to include plenty of fruits and vegetables. \n2.

由于我观察到映射并未使用text，因此我没有加入此字段：

提示列明不一致，但是映射并未看到使用text

使用原本默认数据集会报错。

[LumenScope]

补充：修改映射为

def SYSTEM_map_fn(example):
    return {
        'conversation': [{
            'system': f"{example['instruction']}",
            'input': f"{example['input']}",
            'output': example['output']
        }]
    }

之后再使用自定义数据集仍然报错：

@LumenScope 首先，是 map fn 的定义方式，mmengine 的 config 没有办法在 config 文件内定义新的函数，只能通过 import 的方式，具体见

https://github.com/InternLM/xtuner/tree/main/examples/demo_data/multi_turn_2#config

其次，对于自定义的数据集，可以通过 xtuner check-custom-dataset $CONFIG 检查格式哪里有错误

最后，可以通过 xtuner log-dataset $CONFIG 来查看转换后的数据样式
