三、模型部署核心步骤

3.1 显存优化方案对比

mermaid

3.2 基础部署代码(INT4量化)

from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig

# 量化配置
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_use_double_quant=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16
)

# 加载模型和分词器
tokenizer = AutoTokenizer.from_pretrained("./")
model = AutoModelForCausalLM.from_pretrained(
    "./",
    quantization_config=bnb_config,
    device_map="auto",
    trust_remote_code=True
)

# 测试推理
inputs = tokenizer.apply_chat_template(
    [{"role": "user", "content": "证明费马小定理"}],
    return_tensors="pt",
    add_generation_prompt=True
).to("cuda")

outputs = model.generate(
    inputs,
    max_new_tokens=1024,
    temperature=0.6,
    top_p=0.95,
    do_sample=True
)

print(tokenizer.decode(outputs[0][len(inputs[0]):], skip_special_tokens=True))

3.3 高级优化:YaRN上下文扩展

当处理超过8192 tokens的长文本时,需启用YaRN(Yet Another RoPE Scaling)技术:

# 修改config.json添加以下配置
"rope_scaling": {
    "type": "yarn",
    "factor": 4.0,
    "original_max_position_embeddings": 32768
}

# 代码中应用
model.config.rope_scaling = {
    "type": "yarn",
    "factor": 4.0,
    "original_max_position_embeddings": 32768
}

⚠️ 注意:YaRN可能略微降低短文本性能,建议按实际需求启用

四、性能调优与问题解决

4.1 推理速度优化参数

参数默认值优化值效果
max_new_tokens5121024减少批次切换开销
temperature0.70.6降低随机性,加速解码
top_p0.90.95保持多样性同时提高生成效率
do_sampleTrueFalse确定性解码提速30%
batch_size14批量处理提速2-3倍

4.2 常见错误解决方案

4.2.1 显存溢出问题

mermaid

解决方案代码:

# 启用梯度检查点节省显存
model.gradient_checkpointing_enable()

# 限制最大上下文
tokenizer.padding_side = "left"  # 左填充更高效
inputs = tokenizer(..., truncation=True, max_length=4096)
4.2.2 推理速度过慢

检查以下优化项是否启用:

# 启用Flash Attention 2.0
model = AutoModelForCausalLM.from_pretrained(
    "./",
    ...,
    attn_implementation="flash_attention_2"
)

# 设置推理模式
model.eval()
with torch.no_grad():
    outputs = model.generate(...)

五、实战场景应用案例

5.1 数学推理任务

# 数学问题求解示例
prompt = """
<think>
Got it, let's try to solve this problem step by step. The problem says: Let a, b be positive real numbers such that ab = a + b + 3. Determine the range of possible values for a + b. 

First, I remember that for problems involving positive real numbers and products/sums, the AM-GM inequality might be useful. AM-GM states that for positive numbers, the arithmetic mean is at least the geometric mean. Let me denote S = a + b and P = ab. The problem gives P = S + 3. 

Since a and b are positive reals, by AM-GM, we have S/2 ≥ √(ab), which implies S ≥ 2√(ab). Since P = ab = S + 3, we can substitute that in: S ≥ 2√(S + 3). Now we have an inequality in terms of S. Let's square both sides to eliminate the square root, but we have to be careful because squaring is only valid if both sides are non-negative, which they are here since S is a sum of positive numbers.

So squaring both sides: S² ≥ 4(S + 3) → S² - 4S - 12 ≥ 0. Let's solve the quadratic equation S² - 4S - 12 = 0. Using the quadratic formula: S = [4 ± √(16 + 48)]/2 = [4 ± √64]/2 = [4 ± 8]/2. So the roots are (4+8)/2=6 and (4-8)/2=-2. Since S = a + b is positive, we discard the negative root. The quadratic S² -4S -12 factors as (S-6)(S+2), so the inequality (S-6)(S+2) ≥0 holds when S ≤ -2 or S ≥6. Since S is positive, the solution is S ≥6. 

Wait, but we need to check if equality is possible. If S=6, then ab=6+3=9. By AM-GM equality condition, a=b, so a=b=3. Then ab=9 and a+b=6, which satisfies ab=a+b+3 (9=6+3). So the minimum value is 6, and there's no upper bound because if we let a approach infinity, then b=(a+3)/(a-1) approaches 1, so a + b approaches infinity. Therefore, the range of a + b is [6, ∞).
</think>

To determine the range of possible values for \(a + b\) where \(a, b\) are positive real numbers satisfying \(ab = a + b + 3\), we can follow these steps:

### Step 1: Define Variables and Apply AM-GM Inequality
Let \(S = a + b\) and \(P = ab\). The given condition can be rewritten as:
\[ P = S + 3 \]
By the Arithmetic Mean-Geometric Mean (AM-GM) inequality for positive real numbers:
\[ \frac{a + b}{2} \geq \sqrt{ab} \]
Substituting \(S\) and \(P\), we get:
\[ \frac{S}{2} \geq \sqrt{P} \]

### Step 2: Substitute \(P = S + 3\) and Solve Inequality
Substitute \(P = S + 3\) into the inequality:
\[ \frac{S}{2} \geq \sqrt{S + 3} \]
Square both sides (valid since both sides are non-negative):
\[ \left(\frac{S}{2}\right)^2 \geq S + 3 \]
\[ \frac{S^2}{4} \geq S + 3 \]
Multiply through by 4:
\[ S^2 \geq 4S + 12 \]
Rearrange into a quadratic inequality:
\[ S^2 - 4S - 12 \geq 0 \]

### Step 3: Solve the Quadratic Equation
Factor the quadratic expression:
\[ (S - 6)(S + 2) \geq 0 \]
The roots are \(S = 6\) and \(S = -2\). Since \(a, b\) are positive, \(S = a + b > 0\), so we consider \(S \geq 6\).

### Step 4: Verify Equality Condition
Equality in AM-GM holds when \(a = b\). Substituting \(a = b\) into \(ab = a + b + 3\):
\[ a^2 = 2a + 3 \]
\[ a^2 - 2a - 3 = 0 \]
Solving gives \(a = 3\) (since \(a > 0\)), so \(a = b = 3\) and \(S = 6\).

### Conclusion
The range of \(a + b\) is \(\boxed{[6, +\infty)}\).
