Machine Learning in Elixir: Chapter 6 Axon.Display.as_table does not work (Page 133)
Please guide me in the right direction. I am able to get .as_graph() to display the model correctly
Axon.Display.as_graph(model, template)
however when I try to run .as_table() I get an error (CAUTION: wall of error text follows):
Axon.Display.as_table(model, template)

Perhaps not hyper important as the graph contains the same info but it is nice how the table has the labels.

Removing specific versions or updating to the latest available version corrected the issue for me. Pol Valente was kind enough to update the Axon lib, thanks Pol!
