From 597c8100342f645134d32e8668c222f7d42f4a7d Mon Sep 17 00:00:00 2001 From: BobAi Date: Thu, 14 Aug 2025 20:23:57 +1000 Subject: [PATCH] Fix installer indexing hang and improve user experience MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ๐Ÿ”ง Script Handling Improvements: - Fix infinite recursion in bash wrapper for index/search commands - Improve embedding system diagnostics with intelligent detection - Add timeout protection and progress indicators to installer test - Enhance interactive input handling with graceful fallbacks ๐ŸŽฏ User Experience Enhancements: - Replace confusing error messages with educational diagnostics - Add RAG performance tips about model sizing (4B optimal, 8B+ overkill) - Correct model recommendations (qwen3:4b not qwen3:3b) - Smart Ollama model detection shows available models - Clear guidance for next steps after installation ๐Ÿ›  Technical Fixes: - Add get_embedding_info() method to CodeEmbedder class - Robust test prompt handling with /dev/tty input - Path validation and permission fixing in test scripts - Comprehensive error diagnostics with actionable solutions Installation now completes reliably with clear feedback and guidance. --- install_mini_rag.sh | 130 ++++++++++++++++++++++++++-------- mini_rag/ollama_embeddings.py | 25 +++++++ rag-mini | 4 +- 3 files changed, 127 insertions(+), 32 deletions(-) diff --git a/install_mini_rag.sh b/install_mini_rag.sh index a9a18d3..7dbf2cd 100755 --- a/install_mini_rag.sh +++ b/install_mini_rag.sh @@ -188,12 +188,13 @@ check_ollama() { echo "" echo -e "${CYAN}๐Ÿ’ก Pro tip: Download an LLM for AI-powered search synthesis!${NC}" - echo -e " Lightweight: ${GREEN}ollama pull qwen3:0.6b${NC} (~400MB, very fast)" - echo -e " Balanced: ${GREEN}ollama pull qwen3:1.7b${NC} (~1GB, good quality)" - echo -e " Excellent: ${GREEN}ollama pull qwen3:3b${NC} (~2GB, great for this project)" - echo -e " Premium: ${GREEN}ollama pull qwen3:8b${NC} (~5GB, amazing results)" + echo -e " Lightweight: ${GREEN}ollama pull qwen3:0.6b${NC} (~500MB, very fast)" + echo -e " Balanced: ${GREEN}ollama pull qwen3:1.7b${NC} (~1.4GB, good quality)" + echo -e " Excellent: ${GREEN}ollama pull qwen3:4b${NC} (~2.5GB, sweet spot for most users)" + echo -e " Maximum: ${GREEN}ollama pull qwen3:8b${NC} (~5GB, slower but top quality)" echo "" - echo -e "${BLUE}Creative possibilities: Try mistral for storytelling, or qwen3-coder for development!${NC}" + echo -e "${BLUE}๐Ÿง  RAG works great with smaller models! 4B is usually perfect.${NC}" + echo -e "${BLUE}Creative possibilities: Try mistral for storytelling, qwen2.5-coder for development!${NC}" echo "" return 0 @@ -558,7 +559,36 @@ print(f'โœ… Embedding system: {info[\"method\"]}') " 2>/dev/null; then print_success "Embedding system working" else - print_warning "Embedding test failed, but system should still work" + echo "" + echo -e "${YELLOW}โš ๏ธ System Check${NC}" + + # Smart diagnosis - check what's actually available + if command_exists ollama && curl -s http://localhost:11434/api/version >/dev/null 2>&1; then + # Ollama is running, check for models + local available_models=$(ollama list 2>/dev/null | grep -E "(qwen3|llama|mistral|gemma)" | head -5) + local embedding_models=$(ollama list 2>/dev/null | grep -E "(embed|bge)" | head -2) + + if [[ -n "$available_models" ]]; then + echo -e "${GREEN}โœ… Ollama is running with available models${NC}" + echo -e "${CYAN}Your setup will work great!
