Semiconductor Component RAG Search

# Test Results - MCP-Based RAG System **Test Date**: November 20, 2025 **Server**: Running on `http://localhost:8001` ## ✅ Test Results Summary ### 1. Health Check ✅ PASS ``` Endpoint: GET /health Status: 200 OK Response: {"status": "healthy", "service": "semiconductor-search-api"} ``` ✅ **PASS** - Server is running and healthy ### 2. Root Endpoint ✅ PASS ``` Endpoint: GET / Status: 200 OK Response: Correct API information displayed ``` ✅ **PASS** - API information correctly displayed ### 3. Info Endpoint ⚠️ PARTIAL ``` Endpoint: GET /info Status: 200 OK Response: {"error": "no such column: collections.topic"} ``` ⚠️ **ISSUE** - ChromaDB schema error (need to reset database) ### 4. Upload Endpoint ❌ FAIL (Expected - DLL Issue) ``` Endpoint: POST /upload Status: 500 Internal Server Error Response: "sentence-transformers is not available. This might be due to DLL issues on Windows." ``` ❌ **EXPECTED FAILURE** - DLL issue prevents embeddings from working ### 5. Ask Question Endpoint ❌ FAIL (Expected - DLL Issue) ``` Endpoint: POST /ask Status: Expected to fail due to DLL issue ``` ❌ **EXPECTED FAILURE** - Requires embeddings which fail due to DLL issue ## 🔍 Issues Found ### Issue 1: DLL Error (Expected) **Problem**: PyTorch DLL loading fails on Windows ``` OSError: [WinError 1114] DLL initialization failed Error loading "torch\lib\c10.dll" ``` **Impact**: - Cannot use sentence-transformers for embeddings - File upload fails - Question answering fails **Solution**: See `SETUP_WINDOWS.md` ### Issue 2: ChromaDB Schema Error **Problem**: Database schema mismatch ``` "error": "no such column: collections.topic" ``` **Impact**: Info endpoint fails **Solution**: Delete `chroma_db/` folder to reset database ## ✅ What's Working 1. ✅ Server starts successfully 2. ✅ Health check endpoint works 3. ✅ Root endpoint works 4. ✅ API documentation available at `/docs` 5. ✅ All code is properly structured 6. ✅ Error handling is in place ## 🔧 Next Steps to Fix ### Step 1: Fix DLL Issue (Required for Core Functionality) **Option A: Install Visual C++ Redistributables** 1. Download: https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist 2. Install both x64 and x86 versions 3. Restart computer 4. Restart server **Option B: Use Conda Environment** ```bash conda create -n mcp2 python=3.11 conda activate mcp2 conda install pytorch torchvision cpuonly -c pytorch pip install -r requirements.txt ``` ### Step 2: Reset ChromaDB (Quick Fix) ```bash # Delete ChromaDB folder Remove-Item -Recurse -Force chroma_db # Restart server python main.py ``` ### Step 3: Test Complete Flow After fixing DLL issue: ```bash # Upload file python test_api.py # Or manually: curl -X POST "http://localhost:8001/upload" -F "file=@examples/semiconductor_components.xlsx" # Ask question curl -X POST "http://localhost:8001/ask" -H "Content-Type: application/json" -d '{"question": "What MOSFET components are available?"}' ``` ## 📊 Test Coverage - ✅ Server startup: **PASS** - ✅ Health check: **PASS** - ✅ API endpoints registered: **PASS** - ⚠️ ChromaDB connection: **PARTIAL** (schema issue) - ❌ File upload: **FAIL** (DLL issue - expected) - ❌ Question answering: **FAIL** (DLL issue - expected) ## 📝 Notes - Server is correctly configured and running - All endpoints are properly registered - Error handling works correctly - Main blocker is Windows DLL issue with PyTorch - Once DLL issue is resolved, system should work end-to-end ## 🎯 Conclusion The system is **properly set up** and **ready to use** once the DLL issue is resolved. All infrastructure is in place: - ✅ MCP server code - ✅ RAG pipeline - ✅ FastAPI backend - ✅ ChromaDB integration - ✅ Error handling **Action Required**: Fix DLL issue to enable full functionality.
