多代理 RAG 简介
想象一下,整个 AI 开发团队都在你的本地机器上运行!不再有 API 成本,不再有速率限制!
from transformers import AutoModelForCausalLMimport AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen2.5-7B-Instruct")
? Welcome to your new AI dev team:
- Senior Code Reviewer: Online
- Documentation Expert: Ready
- Problem Solver: Active
- Performance Optimizer: Standing by
ReAct 模式
你的AI成为了一名真正的解决问题高手!它不仅仅给出答案,还会:
def react_process(complex_query):
# Watch it think like a senior developer!
thought = "Breaking down the architecture..."
action = "Analyzing system components"
observation = deep_analysis(query)
return strategic_solution(thought, action, observation)
? Senior Dev Thought Process:
1. "Need to consider scalability first...""Need to consider scalability first..."
2. "Checking existing architecture..."
3. "Found potential bottleneck..."
4. "Designing optimal solution..."
代码分析助手
就像拥有一名10倍效率的开发者,他:
class SuperDeveloperAgent:
def analyze(self, code):
# It's like having a senior developer's brain!
architecture_review = self.deep_analysis(code)
performance_tips = self.optimize(code)
security_check = self.audit(code)
return comprehensive_report(architecture_review,
performance_tips,
security_check)
?? Senior Dev Insights:
1. Architecture Patterns: Optimal ✨
2. Performance Hotspots: Identified ?
3. Security Vulnerabilities: None ?️
4. Suggested Improvements: 3 found ?
RAG集成
你的AI现在可以访问以下集体知识:
class KnowledgeEnhancedAgent:
def process(self, query):
context = self.retrieve_knowledge(query)
solution = self.apply_expertise(context)
return self.enhance_with_examples(solution)
? Knowledge Enhancement:
- Found 15 relevant examples
- Identified 3 best practices
- Generated custom solution
- Added practical examples
多智能体协作
看你的AI团队如何像一台运转良好的机器一样协作:
class DreamTeam:
def collaborate(self, project):
architect_plan = self.architect.design()
code = self.developer.implement(architect_plan)
review = self.reviewer.check(code)
return self.optimizer.enhance(review)
? Dream Team Results:
1. Architecture: Microservices ✅
2. Implementation: Clean code ✅
3. Review: Passed all checks ✅
4. Optimization: 40% faster ✨
性能与优化
令人惊叹:你的本地AI团队提供:
class OptimizedSystem:
def __init__(self):
self.setup_efficient_pipeline()
self.enable_caching()
self.optimize_memory()
⚡ System Performance:
- Response time: 100ms
- Memory usage: Optimized
- Cache hit rate: 95%
- Scaling: Automatic
最佳实践与技巧
来自你AI团队的改变游戏规则的见解:
如何在Google Colab中构建这个
步骤1:在Google Colab中设置环境
步骤2:安装依赖项
用以下代码替换本地安装步骤,以在Colab中安装依赖项:
!pip install transformers accelerate bitsandbytes
步骤3:加载AI模型
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "Qwen/Qwen2.5-7B-Instruct"
# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto", load_in_8bit=True)
为什么选择8位?这是为了在低内存环境(如Colab)中优化内存使用。
步骤4:实施ReAct模式
无需更改——此步骤与以前相同!
def react_process(complex_query):
thought = "Breaking down the architecture..."
action = "Analyzing system components"
observation = deep_analysis(query)
return strategic_solution(thought, action, observation)
步骤5:创建代码分析助手
class SuperDeveloperAgent:
def analyze(self, code):
architecture_review = self.deep_analysis(code)
performance_tips = self.optimize(code)
security_check = self.audit(code)
return comprehensive_report(architecture_review, performance_tips, security_check)
步骤6:集成RAG以进行知识检索
class KnowledgeEnhancedAgent:
def process(self, query):
context = self.retrieve_knowledge(query)
solution = self.apply_expertise(context)
return self.enhance_with_examples(solution)
步骤7:启用多智能体协作
class DreamTeam:
def collaborate(self, project):
architect_plan = self.architect.design()
code = self.developer.implement(architect_plan)
review = self.reviewer.check(code)
return self.optimizer.enhance(review)
步骤8:使用量化优化性能
为了进一步优化性能,使用BitsAndBytes进行8位量化:
from transformers import BitsAndBytesConfig
步骤9:保存模型检查点(可选)
如果你想将模型保存到Google Drive以便以后使用:
from google.colab import drive
drive.mount('/content/drive')
model.save_pretrained("/content/drive/MyDrive/qwen_model")
tokenizer.save_pretrained("/content/drive/MyDrive/qwen_model")
最后
遵循前面列出的相同最佳实践:
