Subject: [x3d-public] testing x3d python jupyter notebook #0<br>

Content-Type: text/plain; charset="utf-8"<br>
<br>
Hello Masaki, thanks for your help with setting up Jupyter notebook on my system.<br>
<br>
<a href="https://test-jupyter.readthedocs.io/en/latest/install.html" rel="noreferrer" target="_blank">https://test-jupyter.readthedocs.io/en/latest/install.html</a><br>
<br>
Attached please find my first Jupyter notebook that includes an x3d scene. Also available as<br>
<br>
<a href="https://www.web3d.org/x3d/stylesheets/python/jupyter/HelloJupyterNotebook0.ipynb" rel="noreferrer" target="_blank">https://www.web3d.org/x3d/stylesheets/python/jupyter/HelloJupyterNotebook0.ipynb</a><br>
<br>
As discussed, it assumes that x3d.py has already been downloaded and is available in a PYTHONPATH directory.<br>
<br>
<a href="https://www.web3d.org/x3d/stylesheets/python/python.html" rel="noreferrer" target="_blank">https://www.web3d.org/x3d/stylesheets/python/python.html</a><br>
<br>
Please let me know if this notebook works for you.<br>
<br>
It is also viewable via jupyter's nbviewer service at<br>
<br>
<a href="https://nbviewer.jupyter.org/urls/www.web3d.org/x3d/stylesheets/python/jupyter/HelloJupyterNotebook0.ipynb" rel="noreferrer" target="_blank">https://nbviewer.jupyter.org/urls/www.web3d.org/x3d/stylesheets/python/jupyter/HelloJupyterNotebook0.ipynb</a><br>
<br>
Interestingly, at first this copied notebook appears to load the x3d.py package on the jupyter nbviewer server without prior configuration incantations, since the forced "error" is displayed. However by looking at the source, it appears that the TypeError markup is saved in the JSON source. So the shared nbviewer version of the notebook must be a published version that has been run, earlier, saved/shared and is later re-runnable. (Hence "viewer" in the name nbviewer.)<br>
<br>
I am next trying to configure my mailer to launch such notebooks. Not sure it is possible.<br>
<br>
Onward we go... having fun with Python X3D! Domo arigato 8)<br>
<br>
all the best, Don<br>
