Ray Error when running ray.init() on a Jupyter Notebook with an EMR cluster attached

When attempting to initialize Ray on an EMR cluster that bootstraps the init script in this repo, I'm hitting the following error:
My goal is to utilize Ray in a Jupyter notebook that has an EMR cluster attached. I created a small cluster which bootstraps the init script in this repo. I've created a PySpark notebook, where I run

```
import ray
ray.init()
```

This then produces the following error:

```
An error was encountered:
