Python API调用示例
from transformers import AutoTokenizer, AutoModelForCausalLM
# 加载模型和tokenizer
model_name = "deepseek-ai/DeepSeek-R1-Distill-Llama-70B"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto")

2.** 提示词设计 **:
- 避免添加系统提示,所有指令应包含在用户提示中
- 对于数学问题,建议添加指令:"Please reason step by step, and put your final answer within \boxed{}."
- 为确保模型进行充分推理,建议强制模型以" \n"开始输出
3.** 性能评估 **:评估模型性能时,建议进行多次测试并取平均值。

实际应用案例
数学问题求解
用户问题:求解方程 x² + 5x + 6 = 0
模型输入:<think>\nPlease reason step by step, and put your final answer within \boxed{}. Solve the equation x² + 5x + 6 = 0.
模型输出:<think>\nTo solve the quadratic equation \(x^2 + 5x + 6 = 0\), we can use the factoring method.
First, we need to find two numbers that multiply to 6 (the constant term) and add up to 5 (the coefficient of the x term).
The factors of 6 are: 1 and 6, 2 and 3.
Checking these pairs:
- 1 + 6 = 7 (not 5)
- 2 + 3 = 5 (this is the pair we need)
So, we can rewrite the middle term using these two numbers:
\(x^2 + 2x + 3x + 6 = 0\)
Now, we factor by grouping:
\(x(x + 2) + 3(x + 2) = 0\)
Notice that both terms have a common factor of (x + 2):
\((x + 2)(x + 3) = 0\)
To find the solutions, we set each factor equal to zero:
1. \(x + 2 = 0 \implies x = -2\)
2. \(x + 3 = 0 \implies x = -3\)
So the solutions to the equation are \(x = -2\) and \(x = -3\).\boxed{-2, -3}
代码生成
用户问题:编写一个Python函数,实现快速排序算法
模型输入:<think>\nPlease write a Python function to implement the quicksort algorithm. Explain your code step by step.
模型输出:<think>\nTo implement the quicksort algorithm in Python, we can follow these steps:
1. Choose a pivot element from the array.
2. Partition the array into elements less than the pivot, the pivot itself, and elements greater than the pivot.
3. Recursively apply quicksort to the sub-arrays of elements less than and greater than the pivot.
Here's the implementation:
def quicksort(arr):
# Base case: if the array has 0 or 1 element, it's already sorted
if len(arr) <= 1:
return arr
# Choose the pivot (here we use the last element)
pivot = arr[-1]
# Partition the array into elements less than, equal to, and greater than pivot
less_than_pivot = [x for x in arr[:-1] if x <= pivot]
greater_than_pivot = [x for x in arr[:-1] if x > pivot]
# Recursively sort the sub-arrays and combine with the pivot
return quicksort(less_than_pivot) + [pivot] + quicksort(greater_than_pivot)
Explanation:
- The base case handles arrays that are already sorted (length 0 or 1).
- We choose the last element as the pivot for simplicity, but other strategies (like median-of-three) can be used for better performance.
- List comprehensions are used to partition the array into elements less than/equal to and greater than the pivot.
- The function recursively sorts the sub-arrays and combines them with the pivot to produce the final sorted array.
Example usage:
arr = [3, 6, 8, 10, 1, 2, 1]
sorted_arr = quicksort(arr)
print(sorted_arr) # Output: [1, 1, 2, 3, 6, 8, 10]
