Apps only rendering partially

[austinmw]

I'm running JupyterLab through AWS SageMaker. I've downloaded the dash-sample-apps repository and modified a couple of the app.py files with:

import jupyterlab_dash
viewer = jupyterlab_dash.AppViewer()
viewer.show(app)

When I run one of these sample apps from a jupyterlab cell like this: %run -i '/home/ec2-user/SageMaker/dash-sample-apps/apps/dash-live-model-training/app.py'

The Dash pane pops up, and the app loads, but only partially. Very simple apps seem to load in their entirety, but more complicated graphics don't get displayed.

Here are two examples of partial loading:

@austinmw have you solved it yet? I am facing to the same problem.
