From 2869ab3c5fd8da868831f7abdca8f82b798d125b Mon Sep 17 00:00:00 2001 From: Surapong Kanoktipsatharporn Date: Mon, 20 Oct 2025 15:24:51 +0700 Subject: [PATCH] feat: Separate embedding configuration from chat model configuration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements a comprehensive solution for separating embedding and chat model configurations, enabling flexible provider combinations and graceful handling of embedding failures. ## Problem Statement Previously, the TradingAgents memory system used the same backend_url for both chat models and embeddings. This caused critical failures when: - Using OpenRouter for chat (doesn't support OpenAI embedding endpoints) - Using Anthropic/Google for chat (don't provide embeddings) - The embedding endpoint returned HTML error pages instead of JSON - Users wanted to mix providers (e.g., OpenRouter chat + OpenAI embeddings) Error example: AttributeError: 'str' object has no attribute 'data' # Caused by: OpenRouter returned HTML page instead of embedding JSON ## Solution Implemented three key features: 1. **Separate Embedding Client Configuration** - New config parameters independent of chat LLM settings - embedding_provider: "openai", "ollama", or "none" - embedding_backend_url: Separate API endpoint - embedding_model: Specific model to use - enable_memory: Boolean flag to enable/disable memory 2. **Multiple Provider Support** - OpenAI: Production-grade embeddings (recommended) - Ollama: Local embeddings for offline/development - None: Disable memory system entirely 3. **Graceful Fallback** - System continues when embeddings fail - Comprehensive error logging - Memory operations return empty results instead of crashing - Agents function without historical context when memory disabled ## Changes ### Core Framework - tradingagents/default_config.py: Added 4 new embedding config params - tradingagents/agents/utils/memory.py: Complete refactor with error handling - tradingagents/graph/trading_graph.py: Separated embedding initialization ### CLI/User Interface - cli/utils.py: Added select_embedding_provider() function - cli/main.py: Added Step 7 for embedding provider selection ### Documentation (New Files) - docs/EMBEDDING_CONFIGURATION.md: Complete usage guide (381 lines) - docs/EMBEDDING_MIGRATION.md: Implementation details (374 lines) - CHANGELOG_EMBEDDING.md: Release notes (225 lines) - FEATURE_EMBEDDING_README.md: Branch overview (418 lines) ### Testing & Verification - tests/test_embedding_config.py: Comprehensive test suite - verify_config.py: Simple config verification script ## Example Usage ```python # OpenRouter for chat, OpenAI for embeddings config = { "llm_provider": "openrouter", "backend_url": "https://openrouter.ai/api/v1", "deep_think_llm": "deepseek/deepseek-chat-v3-0324:free", "embedding_provider": "openai", "embedding_backend_url": "https://api.openai.com/v1", "embedding_model": "text-embedding-3-small", "enable_memory": True, } ``` ## Backward Compatibility ✅ 100% Backward Compatible - No breaking changes! Existing configurations work without modification. Smart defaults applied when embedding settings are omitted. ## Testing - All core files pass diagnostics with no errors - Configuration verification script passes all checks - Supports scenarios: OpenRouter+OpenAI, All Ollama, Disabled Memory - Graceful fallback tested for invalid URLs and missing API keys ## Benefits - Enables using OpenRouter/other providers for chat - Reduces costs (can use local embeddings or disable memory) - Improves reliability (graceful degradation on failures) - Maintains full backward compatibility - Comprehensive documentation and examples Fixes: OpenRouter compatibility issues Closes: Embedding/chat provider coupling Implements: Graceful fallback for memory operations --- .env.example | 13 +- CHANGELOG_EMBEDDING.md | 225 +++++++++++++ COMMIT_MESSAGE.txt | 104 ++++++ FEATURE_EMBEDDING_README.md | 418 +++++++++++++++++++++++++ IMPLEMENTATION_SUMMARY.md | 451 +++++++++++++++++++++++++++ cli/main.py | 79 +++-- cli/utils.py | 170 ++++++++-- docs/EMBEDDING_CONFIGURATION.md | 381 ++++++++++++++++++++++ docs/EMBEDDING_MIGRATION.md | 374 ++++++++++++++++++++++ tests/test_embedding_config.py | 221 +++++++++++++ tradingagents/agents/utils/memory.py | 345 +++++++++++++++----- tradingagents/default_config.py | 11 +- tradingagents/graph/trading_graph.py | 99 +++++- verify_config.py | 155 +++++++++ 14 files changed, 2893 insertions(+), 153 deletions(-) create mode 100644 CHANGELOG_EMBEDDING.md create mode 100644 COMMIT_MESSAGE.txt create mode 100644 FEATURE_EMBEDDING_README.md create mode 100644 IMPLEMENTATION_SUMMARY.md create mode 100644 docs/EMBEDDING_CONFIGURATION.md create mode 100644 docs/EMBEDDING_MIGRATION.md create mode 100644 tests/test_embedding_config.py create mode 100644 verify_config.py diff --git a/.env.example b/.env.example index 1e257c3c..c98e5084 100644 --- a/.env.example +++ b/.env.example @@ -1,2 +1,11 @@ -ALPHA_VANTAGE_API_KEY=alpha_vantage_api_key_placeholder -OPENAI_API_KEY=openai_api_key_placeholder \ No newline at end of file +# For OpenAI (default) +OPENAI_API_KEY=your_openai_api_key_here +ALPHA_VANTAGE_API_KEY=your_alpha_vantage_key_here +TRADINGAGENTS_LLM_PROVIDER=openai +TRADINGAGENTS_BACKEND_URL=https://api.openai.com/v1 + +# For OpenRouter +# OPENAI_API_KEY=your_openrouter_api_key_here # OpenRouter uses OPENAI_API_KEY env var +# ALPHA_VANTAGE_API_KEY=your_alpha_vantage_key_here +# TRADINGAGENTS_LLM_PROVIDER=openrouter +# TRADINGAGENTS_BACKEND_URL=https://openrouter.ai/api/v1 diff --git a/CHANGELOG_EMBEDDING.md b/CHANGELOG_EMBEDDING.md new file mode 100644 index 00000000..68ac6cf4 --- /dev/null +++ b/CHANGELOG_EMBEDDING.md @@ -0,0 +1,225 @@ +# Changelog -
