Support for Amazon SageMaker Studio Lab

[giswqs]

Amazon SageMaker Studio is a free cloud computing platform, similar to Binder but users can install packages and save files permanently. It seems localtileserver is not working on SageMaker, even after running the following code. Any advice?

import os
os.environ["LOCALTILESERVER_CLIENT_PREFIX"] = "proxy/{port}"

I haven't used sage maker yet but it seems to be gaining a lot of traction... I'll see what I can do to get this to work.

[banesullivan]

I have no idea where to begin with this... I signed up for a handful of different "SageMaker" things and could not figure out how to launch a notebook environment anywhere... this whole thing has left me quite confused.

Anywho, I think "SageMaker Studio Lab" is the platform? right? If so, I'm waitlisted:

[giswqs]

@banesullivan Yes, SageMaker Studio Lab is the free version, something similar to Google Colab. It might take a few hours /days to get the account approved. Other SageMaker products are not free.

[banesullivan]

I finally have an account, but I'm having trouble getting ipywidgets to work at all... tried restarting JupyterLab from the sagemaker menu but no luck...

Error displaying widget: model not found

[banesullivan]

However, from the looks of it. SageMaker truly is just JupyterLab (unlike Google Colab) so setting up Jupyter-server-proxy to get this working should be all the same

[giswqs]

Yes, ipyleaflet might not work with SageMaker Studio. Try folium

[banesullivan]

It should work... the JupyterLab just needs to be relaunched/rebuilt after ipywidgets are installed... just not sure how to trigger that with SageMaker.

Will try folium in the meantime

Indeed, same set up with Jupyter-server-proxy, just need the right prefix. This works as:

import os
os.environ['LOCALTILESERVER_CLIENT_PREFIX'] = f"studiolab/default/jupyter/proxy/{{port}}"

---

On MyBinder, this prefix is easy to get with the JUPYTERHUB_SERVICE_PREFIX environment variable. Unfortunately, I do not see anything like this in the environment on sagemaker.... though studiolab/default/jupyter/ seems standard enough that this is probably the prefix in any environment -- @giswqs, you might know better than I

[banesullivan]

Really IMO, we should raise issues like this upstream in jupyter-server-proxy and see if they can make this easier to do in Colab, SageMaker, MyBinder, etc.

[banesullivan]

I'll add it to my to do list to open an issue upstream outlining the need clearly

[giswqs]

That's fantastic! How did you figure out the prefix?

[banesullivan]

Just looking at the URL in the browser 😉

[giswqs]

Is it possible to get the browser URL programmatically and extract the prefix from the URL?

[banesullivan]

I think @artttt was able to do this. See #101 (comment)
