# ✅ Migration Complete - Multi-Provider AI Support Verified
|
|
|
|
## Test Results
|
|
|
|
### ✅ All Tests Passed!
|
|
|
|
The migration to support multiple AI providers (including Ollama) is **complete and working**.
|
|
|
|
**Test Results:**
|
|
```
|
|
Test 1: Importing LLM Factory... ✅
|
|
Test 2: Importing default config... ✅
|
|
Test 3: Creating Ollama configuration... ✅
|
|
Test 4: Checking langchain-community package... ✅
|
|
Test 5: Creating Ollama LLM instance... ✅
|
|
Test 6: Testing LLM with simple query... ✅
|
|
Test 7: Creating TradingAgentsGraph with Ollama... ✅
|
|
```
|
|
|
|
## What Was Fixed
|
|
|
|
### Issue Found
|
|
The `memory.py` module was hardcoded to use OpenAI's API, causing errors when using Ollama.
|
|
|
|
### Solution Applied
|
|
Updated `tradingagents/agents/utils/memory.py` to be provider-agnostic:
|
|
|
|
1. **Detect Provider**: Checks config for `llm_provider` setting
|
|
2. **Conditional Client Creation**: Only creates OpenAI client when needed
|
|
3. **Flexible Embeddings**:
|
|
- Uses OpenAI embeddings for OpenAI provider
|
|
- Uses ChromaDB's default embeddings for Ollama
|
|
4. **Graceful Handling**: Works with or without custom embeddings
|
|
|
|
## How to Use
|
|
|
|
### Quick Test
|
|
|
|
Run the included test script:
|
|
```bash
|
|
python test_ollama.py
|
|
```
|
|
|
|
### Full Example
|
|
|
|
Run a complete trading analysis with Ollama:
|
|
```bash
|
|
python example_ollama.py
|
|
```
|
|
|
|
### In Your Code
|
|
|
|
```python
|
|
from tradingagents.graph.trading_graph import TradingAgentsGraph
|
|
from tradingagents.default_config import DEFAULT_CONFIG
|
|
|
|
# Configure for Ollama
|
|
config = DEFAULT_CONFIG.copy()
|
|
config["llm_provider"] = "ollama"
|
|
config["deep_think_llm"] = "llama3"
|
|
config["quick_think_llm"] = "llama3"
|
|
config["backend_url"] = "http://localhost:11434"
|
|
|
|
# Create graph
|
|
ta = TradingAgentsGraph(config=config, debug=True)
|
|
|
|
# Run analysis
|
|
_, decision = ta.propagate("AAPL", "2024-05-10")
|
|
print(decision)
|
|
```
|

## System Requirements
|
|
|
|
### For Ollama (Local)
|
|
- Ollama installed and running (`ollama serve`)
|
|
- At least one model pulled (`ollama pull llama3`)
|
|
- ~8GB RAM for llama3:8b
|
|
- ~48GB RAM for llama3:70b
|
|
|
|
### For All Providers
|
|
- Alpha Vantage API key (for financial data)
|
|
- Python 3.8+
|
|
- langchain-community (for Ollama)
|
|
|
|
## Performance Notes
|
|
|
|
### Ollama Performance
|
|
- **Speed**: Slower than cloud APIs (depends on hardware)
|
|
- **Cost**: FREE! No API charges
|
|
- **Privacy**: 100% local, no data sent externally
|
|
- **Quality**: Good with llama3, excellent with larger models
|
|
|
|
### Recommendations
|
|
- **Development/Testing**: Use Ollama (free, fast enough)
|
|
- **Production (Quality)**: Use GPT-4o or Claude 3 Opus
|
|
- **Production (Speed)**: Use Groq
|
|
- **Production (Cost)**: Use Google Gemini or Groq
|
|
|
|
## Next Steps
|
|
|
|
1. ✅ **Test passed** - Ollama integration working
|
|
2. ✅ **Memory fixed** - Provider-agnostic embeddings
|
|
3. 📝 **Ready to use** - Example code available
