What are the Lessons Learned

If you're interested in some of the lessons the creators of this tool learned while creating it, all you need to do is follow the python tradition.

Why Make This?

Back in the old days, it was common to write rule-based systems. Systems that do;

Nowadays, it's much more fashionable to use machine learning instead. Something like;

We started wondering if we might have lost something in this transition. Sure, machine learning covers a lot of ground. But we've reached a stage of hype that folks forget that many classification problems can be handled by natural intelligence too.

This made us wonder if we could make machine learning listen more to common sense. There's a lot of things that could go wrong otherwise. If you're interested in examples we might recommend this pydata talk.

I'm getting a PORT error!

You might get an error that looks like;

ERROR:bokeh.server.views.ws:Refusing websocket connection from Origin 'http://localhost:8889';
use --allow-websocket-origin=localhost:8889 or set BOKEH_ALLOW_WS_ORIGIN=localhost:8889
to permit this; currently we allow origins {'localhost:8888'}

This is related to something bokeh cannot do without explicit permission from jupyter. It can't be fixed by this library but you can circumvent this error by running jupyter via;

python -m jupyter lab --port 8889 --allow-websocket-origin=localhost:8889

You can also set an environment variable BOKEH_ALLOW_WS_ORIGIN=localhost:8889.
