[x3d-public] Repairing this Jupyter Notebook is a pain!

[John Carlson]

Vincent, I am trying to duplicate this with Mojo Python in Mojo Playground
JupyterHub.  Sometimes the packages fail to import.  Here's my python code:


from IPython import display, HTML
import x3d
from x3d import X3D
from x3d import metaDiagnostics

# snip, add newModel to context instead of this comment.

str = newModel.Scene.HTML5()

x3dnode = """
<script type='text/javascript' charset="UTF-8" src='
https://x3dom.org/release/x3dom-full.debug.js'> </script>
<link rel='stylesheet' type='text/css' href='
https://x3dom.org/release/x3dom.css'></link>
<style>
 x3d {
     width:720px;
     height:720px;
     border:2px solid black;
}
</style><x3d>"""+str+"""
</x3d>
<script>
window.x3dom.reload()
</script>"""

HTML(x3dnode)


# not sure what I'm doing wrong???

Could this console problem mean something?

Failed to fetch ipywidgets through the "jupyter.widget.control" comm
channel, fallback to fetching individual model state. Reason: Control comm
did not respond in time
_loadFromKernel @ 150.3e1e5adfd821b9b96340.js?v=3e1e5adfd821b9b96340:1

Search for Mojo Playground in google, if you are already enrolled.

Thanks!

John
