On every Jupyter Notebook environment, Jupyter Notifier allows you to select specific cells for notification. For this, Jupyter Notifier injects a button 📷 into your notebook. You can get notified with a sound, a message, or both when code cells terminate. With Jupyter Notifier, you won't be repeatedly checking whether your cell has finished running. github地址： https://github.com/naraB/jupyter-notifier
