🛠️ Troubleshooting

Common Issues & Solutions

Port Already in Use

# Check what's using the port
netstat -ano | findstr ":8001"
netstat -ano | findstr ":5000"

# Kill the process (replace PID with actual process ID)
taskkill /PID <PID> /F

Docker Volume Mount Issues (Windows)

# Use the simplified Docker compose
docker compose -f docker-compose-simple.yml up --build -d

# Or run locally without Docker
python train_model_simple.py
python serving/main_standalone.py

MLflow Connection Issues

# Verify MLflow is running
curl http://localhost:5000

# Check MLflow logs
docker logs stockpricemlpipeline-mlflow-1

Model Not Found

# Train the model first
python train_model_simple.py

# Verify model file exists
ls models/stock_model.pkl
