+
+本次微调的模型我已经上传到了 HuggingFace Hub 上，大家可以进行尝试。
+
+### 安装 mlx-lm
+
+```bash
+pip install mlx-lm
+```
+
+### 生成 SQL
+```
+python -m mlx_lm.generate --model mlx-community/Mistral-7B-v0.1-LoRA-Text2SQL \
+                          --max-tokens 50 \
+                          --prompt "table: students
+columns: Name, Age, School, Grade, Height, Weight
+Q: Which school did Wang Junjian come from?
+A: "
+```
+```
+SELECT School FROM Students WHERE Name = 'Wang Junjian'
+```
+
+
+## [在 MLX 上使用 LoRA 基于 Mistral-7B 微调 Text2SQL（一）](https://wangjunjian.com/mlx/lora/2024/01/23/Fine-tuning-Text2SQL-based-on-Mistral-7B-using-LoRA-on-MLX-1.html)
+
+📌 没有使用模型的标注格式生成数据集，导致不能结束，直到生成最大的 Tokens 数量。
+
+这次我们来解决这个问题。
+
+## 数据集 WikiSQL
+
+- [WikiSQL](https://github.com/salesforce/WikiSQL)
+- [sqllama/sqllama-V0](https://huggingface.co/sqllama/sqllama-V0/blob/main/wikisql.ipynb)
+
+### 修改脚本 mlx-examples/lora/data/wikisql.py
+```py
+if __name__ == "__main__":
+    # ......
+    for dataset, name, size in datasets:
+        with open(f"data/{name}.jsonl", "w") as fid:
+            for e, t in zip(range(size), dataset):
+                """
+                t 变量的文本是这样的：
+                ------------------------
+                <s>table: 1-1058787-1
+                columns: Approximate Age, Virtues, Psycho Social Crisis, Significant Relationship, Existential Question [ not in citation given ], Examples
+                Q: How many significant relationships list Will as a virtue?
+                A: SELECT COUNT Significant Relationship FROM 1-1058787-1 WHERE Virtues = 'Will'</s>
+                """
+                t = t[3:] # 去掉开头的 <s>，因为 tokenizer 会自动添加 <s>
+                json.dump({"text": t}, fid)
+                fid.write("\n")
+```
+
+执行脚本 `data/wikisql.py` 生成数据集。
+
+### 样本示例
+
+```
+table: 1-10753917-1
+columns: Season, Driver, Team, Engine, Poles, Wins, Podiums, Points, Margin of defeat
+Q: Which podiums did the alfa romeo team have?
+A: SELECT Podiums FROM 1-10753917-1 WHERE Team = 'Alfa Romeo'</s>

+## 微调

+- 预训练模型 [mistralai/Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1)
+
+### LoRA 微调
+
+```bash
+python lora.py --model mistralai/Mistral-7B-v0.1 \
+               --train \
+               --iters 600
+```
+```
+Total parameters 7243.436M
+Trainable parameters 1.704M
+python lora.py --model mistralai/Mistral-7B-v0.1 --train --iters 600  50.58s user 214.71s system 21% cpu 20:26.04 total
+```
+
+微调万分之 2.35 （1.704M / 7243.436M * 10000）的模型参数。
+
+LoRA 微调 600 次迭代，耗时 20 分 26 秒，占用内存 46G。
+
+## 评估
+
+计算测试集困惑度（PPL）和交叉熵损失（Loss）。
+
+```bash
+python lora.py --model mistralai/Mistral-7B-v0.1 \
+               --adapter-file adapters.npz \
+               --test

+```
+Iter 100: Test loss 1.351, Test ppl 3.862.
+Iter 200: Test loss 1.327, Test ppl 3.770.
+Iter 300: Test loss 1.353, Test ppl 3.869.
+Iter 400: Test loss 1.355, Test ppl 3.875.
+Iter 500: Test loss 1.294, Test ppl 3.646.
+Iter 600: Test loss 1.351, Test ppl 3.863.
+```
+
+| Iter | Test loss | Test ppl |
