This means you are following a guide for a very old version of Flux. Can you provide a link?

The current version spells this Adam, but also no longer has @epochs, and strongly discourages Flux.params(model). It should look more like this.

Hello, I’ve encountered the same issue. Have you resolved it?
Here is my code.

opt = ADAM(learning_rate)

My Flux is up to date, and there are no missing packages when I check with status. I’m getting the following error. How should I handle it?
