I am trying to use ray on AWS SageMaker in a Jupyter Notebook.
The dashboard GUI not working for me, as it displays a blank page (rendered in browser)
The Ray framework seems to run perhaps needs some debugging / evaluation.
My goal is to access the dashboard feature. Note that I installed Ray with
pip install ray[dashboard]
When ray.init() is called, I got the message about accessing the dashboard at localhost:8265, which is equivalent to https://<aws-notebook-instance>/proxy/8265/ on AWS:
ray.init(
num_cpus = num_cpus,
num_gpus = num_gpus,
ignore_reinit_error = True,
include_webui = None,
webui_host = 'localhost'
)
After some testing, it seemed the dashboard API is there and responsive, but the browser displays only a blank page with embedded Javascript & CSS objects (if viewed in dev mode).
Looking in a GitHub repo, I tested actual API calls under the /api/ path - and some of those return data in a raw format, through the browser didn't do what I intended.
All I could think of is maybe some of the app framework or dependencies weren't installed on the host?
