My model works beautifully in my notebook. Then I try to actually get it into production and I hit a wall, servers, pipelines, things breaking in ways they never did on my laptop. It runs great in the one place nobody but me will ever see it.
More people experience this than they realize.
You can build a model in a notebook, but getting it into production is a wall.
If this sounds familiar, the Library can help you find the bigger picture.
