Trouble launching example notebooks

[villares]

Hi, thanks for creating this resource! I'm very new to cadquery and not very used to Jupyter Notebooks either, so I'm probably doing several things wrong, sorry to take your time.

I'm using Firefox (and tested Chromium too) on Xubuntu 20.04, and I have tried this:
1 - I clicked at the binder launch thing and waited for environment to be setup.
2 - Clicked at the 'examples folder.
3 - Clicked at some example (tried several) and tried the run button, got this:

4 - I noticed a Python 2 kernel so I tried to change to to Python 3 (and then got a no cadquerymodule found error)

Please advise!

Hello there,

Thank you for posting this issue :)

I'll state up front that it has been some time (several years) since I have used this project. I decided to move on from this due to similar issues that you are experiencing, as well as being inexperienced as a developer at the time.

Your probable best bet is to look at more actively maintained (and more up-to-date) work related to this:

• jupyter-cadquery

It's also the case that both jupyter and cadquery have changed and improved since my time working on this, so this notebook may be too out of date to really get set up properly.

As some consolation, I'll try to point you in some useful direction (sorry I can't be of more help)

• The widget library is a specific library called 'ipywidgets', and I remember needing to pin a specific version to work with py2
  • I think I had to pin the version to 7.0.1, or perhaps 6.9.1. Start there perhaps?
• here is the ipywidgets docs as a starting point: Jupyter Widgets

As well, it may be worth re-doing the notebook setup yourself making sure to use the most up-to-date versions of everything.

• Cadquery's repo: CadQuery

Good luck and I hope you can sort things out :)
