Is AbstractLuxContainerLayer abandoned in Lux 1.0.4?

[disadone]

I am going through the tutorial:
https://lux.csail.mit.edu/dev/tutorials/beginner/3_SimpleRNN#Creating-a-Classifier

However, julia tell me

UndefVarError: `AbstractLuxContainerLayer` not defined

Stacktrace:
 [1] getproperty(x::Module, f::Symbol)

Is the tutorial need to be updated?

It is weird, it only happens in jupyter in vscode. Julia file works fine...

You are probably running an older version of Lux (jupyter notebook using a different project perhaps?). AbstractLuxContainerLayer was introduced in LuxCore/Lux v1.

The docs are live updated and CI would fail if any of the examples aren't working
