ERROR: UndefVarError: `setup` not defined when loading setup function in flux

Question

I am using M1 mac (if that helps) and when I tried loading the setup function flux.jl and got the following error. UndefVarError setup not defined

The flux version I am using is 0.13.4. I created a new env to update it to the latest 0.13.17 and I still ended up with the same error.

Any idea how to fix this

using Flux: setup

Somehow you are still using an old version of Flux. Perhaps by changing the env after loading Flux, which won't alter already-loaded code? — mcabbott, Jul 02 '23 at 22:55
I'm using an M1 Mac, and `using Flux: setup` works just fine for me — Mark, Jul 04 '23 at 11:04
