+ ## Introduction
32
+
33
+ Over the past year, we have dedicated significant effort to researching and enhancing the reasoning capabilities of large language models, with a particular focus on their ability to solve arithmetic and mathematical problems. Today, we are delighted to introduce a serise of math-specific large language models of our Qwen2 series, Qwen2-Math and Qwen2-Math-Instruct-1.5B/7B/72B. Qwen2-Math is a series of specialized math language models built upon the Qwen2 LLMs, which significantly outperforms the mathematical capabilities of open-source models and even closed-source models (e.g., GPT4o). We hope that Qwen2-Math can contribute to the scientific community for solving advanced mathematical problems that require complex, multi-step logical reasoning.

36
+ ## Model Details
37
+
38
+
39
+ For more details, please refer to our [blog post](https://qwenlm.github.io/blog/qwen2-math/) and [GitHub repo](https://github.com/QwenLM/Qwen2-Math).
40
+
41
+
42
+ ## Requirements
43
+ * `transformers>=4.40.0` for Qwen2-Math models. The latest version is recommended.
44
+
45
+ > [!Warning]
46
+ > <div align="center">
47
+ > <b>
48
+ > 🚨 This is a must because `transformers` integrated Qwen2 codes since `4.37.0`.

52
+ For requirements on GPU memory and the respective throughput, see similar results of Qwen2 [here](https://qwen.readthedocs.io/en/latest/benchmark/speed_benchmark.html).

+ ### 🤗 Hugging Face Transformers
64
+
65
+ Qwen2-Math can be deployed and inferred in the same way as [Qwen2](https://github.com/QwenLM/Qwen2). Here we show a code snippet to show you how to use the chat model with `transformers`:
66
+
67
+ ```python
68
+ from transformers import AutoModelForCausalLM, AutoTokenizer
69
+
70
+ model_name = "Qwen/Qwen2-Math-7B-Instruct"
71
+ device = "cuda" # the device to load the model onto
72
+
73
+ model = AutoModelForCausalLM.from_pretrained(
74
+ model_name,
75
+ torch_dtype="auto",
76
+ device_map="auto"
77
+ )
78
+ tokenizer = AutoTokenizer.from_pretrained(model_name)
79
+
80
+ prompt = "Find the value of $x$ that satisfies the equation $4x+5 = 6x+7$."
81
+ messages = [
82
+ {"role": "system", "content": "You are a helpful assistant."},
83
+ {"role": "user", "content": prompt}
84
+ ]
85
+ text = tokenizer.apply_chat_template(
86
+ messages,
87
+ tokenize=False,
88
+ add_generation_prompt=True
89
+ )
90
+ model_inputs = tokenizer([text], return_tensors="pt").to(device)
91
+
92
+ generated_ids = model.generate(
93
+ **model_inputs,
94
+ max_new_tokens=512
95
+ )
96
+ generated_ids = [
97
+ output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
98
+ ]
99
+
100
+ response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
101
+ ```
102
+
103
+ ### 🤖 ModelScope
104
+ We strongly advise users, especially those in mainland China, to use ModelScope. `snapshot_download` can help you solve issues concerning downloading checkpoints.
