Hi, I’m trying to follow livebook neural network video

and exploring image classification smart cell, although getting error:

tukan950×1183 59.7 KB

Don’t understand though which module produces the error and how to workaround?
I’m user of erlang 26.1.2 and elixir 1.15.7; livebook itself is 0.11.2

22:36:41.485 [error] Kino.listen with #Function<42.105768164/1 in :erl_eval.expr/6> failed with reason:
