🆘 Troubleshooting Guide

Quick solutions for common issues

🔧 Common Setup Issues

🐍 Python Import Errors

# Verify Python version
python --version  # Should be 3.8+

# Check virtual environment
source venv/bin/activate
pip list | grep Flask

# Test core imports
cd backend && python -c "import app; print('✅ Success')"

🔑 API Key Configuration

# Check .env file exists
ls -la .env

# Verify API key format
cat .env | grep GROQ_API_KEY
# Should show: GROQ_API_KEY=gsk_...

# Test API key validity
curl -H "Authorization: Bearer $GROQ_API_KEY" \
  https://api.groq.com/openai/v1/models

🔌 Port & Network Issues

# Check if port is in use
lsof -i :5002

# Use different port
echo "PORT=5003" >> .env
./run-local.sh

# Check firewall settings
# Ensure port 5002 is open for local development

📦 Dependency Problems

# Clean install
rm -rf venv
python -m venv venv
source venv/bin/activate
pip install --upgrade pip
pip install -r requirements.txt

# Install minimal dependencies only
pip install Flask Werkzeug python-dotenv requests flask-cors groq

🚀 Performance Optimization

⚡ Development Speed

# Frontend-only development
./run-frontend.sh  # Faster UI iteration

# Skip ML dependencies for UI work
pip install Flask Werkzeug python-dotenv requests flask-cors groq

# Use hot reload
export FLASK_DEBUG=True
./run-local.sh

🧠 AI Model Performance

# Cache models locally
export TRANSFORMERS_CACHE=./backend/data/models_cache
export HF_HOME=./backend/data/models_cache

# Use faster models for development
# Prefer llama-3.1-8b-instant over larger models

# Optimize token limits
# Set MAX_TOKENS_DEFAULT=256 for faster responses

🐳 Docker Optimization

# Use .dockerignore
echo "venv/\n*.pyc\n__pycache__/\n.git/" > .dockerignore

# Multi-stage builds
docker build --target production .

# Optimize layer caching
# Put requirements.txt COPY before code COPY

💾 Database Performance

# SQLite optimization
echo "PRAGMA journal_mode=WAL;" | sqlite3 nexusai.db

# Regular cleanup
python -c "from database import get_database; db = get_database(); print('DB size:', db.get_database_stats())"

# Backup before major changes
cp nexusai.db nexusai.db.backup
