Javascript error with 406-3D-pose-estimation-webcam

[ahuckphin]

I can successfully get the webcam feed. However to the left, I see a Javascript error message

Windows

I have now verified I have jupyter-threejs installed. Now getting a different error message:

TypeError: Cannot read properties of undefined (reading 'then')

Did you visualize the results in a browser ? Can you try it with Chrome?

[ahuckphin]

Yes, I'm using browser. Tested with both Edge (Chromium based) and Chrome, same results.

Did you install the Jupyter extension and use Jupyterlab to run this demo?

[ahuckphin]

Yes, I've installed Jupyter extension:

(openvino_env) C:\Users\PSC\openvino_notebooks>jupyter labextension list JupyterLab v3.6.2 c:\users\psc\openvino_env\share\jupyter\labextensions jupyter-threejs v2.4.1 enabled ok (python, pythreejs) jupyterlab-datawidgets v7.1.2 enabled ok jupyterlab_pygments v0.2.2 enabled ok (python, jupyterlab_pygments) @jupyter-widgets/jupyterlab-manager v5.0.6 enabled ok (python, jupyterlab_widgets) Other labextensions (built into JupyterLab) app dir: C:\Users\PSC\openvino_env\share\jupyter\lab

and using Jupyterlab to run the demo
