 ### Testing train.py on this notebook's instance
-Notebook instances in SageMaker allow us allocate more powerful instances (or many instances) to machine learning jobs that require extra power, GPUs, or benefit from parallelization. Before we try exploiting this extra power, it is essential that we test our code thoroughly. We don't want to waste unnecessary compute cycles and resources on jobs that produce bugs instead of insights. If you need to, you can use a subset of your data to run quicker tests. You can also select a slightly better instance resource if your current instance insn't meeting your needs. See the [Instances for ML spreadsheet](https://docs.google.com/spreadsheets/d/1uPT4ZAYl_onIl7zIjv5oEAdwy4Hdn6eiA9wVfOBbHmY/edit?usp=sharing) for guidance.

 #### Logging runtime & instance info
 To compare our local runtime with future experiments, we'll need to know what instance was used, as this will greatly impact runtime in many cases. We can extract the instance name for this notebook using...
