I installed Open3D on Windows and observed that it had to install a whole bunch of packages where some specify specific dependency versions and others don’t.
Installing collected packages: parso, jedi, backcall, wcwidth, prompt-toolkit, decorator, pygments, colorama, pickleshare, ipython-genutils, traitlets, ipython, tornado, pywin32, jupyter-core, python-dateutil, pyzmq, jupyter-client, ipykernel, prometheus-client, pywinpty, terminado, MarkupSafe, jinja2, pycparser, cffi, argon2-cffi, Send2Trash, zipp, importlib-metadata, attrs, pyrsistent, jsonschema, nbformat, testpath, webencodings, bleach, defusedxml, mistune, entrypoints, pandocfilters, nbconvert, notebook, widgetsnbextension, ipywidgets, open3d
In this case the notebook package starting with version 6.1.0 added the argon2-cffi dependency which doesn’t have a macOS wheel available for the latest release which is why it had to build a wheel from source which it failed at in your output. Notebook version 6.1.0 was released July 31st which explains why you ran into this issue just recently.
