Your model doesn't make any random choices. Rather than sampling from a chain, the model is the chain. You need a ~
instead:
julia> m1 = @model begin
mc1 ~ Chain(Normal(0.0, 1.0)) do x Normal(x, 1.0) end
return mc1
end
@model begin
mc1 ~ Chain(Normal(0.0, 1.0)) do x
Normal(x, 1.0)
end
return mc1
end
julia> r1 = rand(m1())
Realized{Random._GLOBAL_RNG,UInt64,Chain{ggfunc-function,Normal{(:μ, :σ), Tuple{Float64, Float64}}}}(MeasureTheory.ResettableRNG{Random._GLOBAL_RNG, UInt64}(Random._GLOBAL_RNG(), 0x7f03d16a3be18246), Chain{ggfunc-function,Normal{(:μ, :σ), Tuple{Float64, Float64}}}(function = (x;) -> begin
(Main).Normal(x, 1.0)
end, Normal{(:μ, :σ), Tuple{Float64, Float64}}((μ = 0.0, σ = 1.0))))
julia> collect(take(r1, 10))

Ah. Stupid mistake. Sorry for bothering and thank you for the answer! Kind greetings!
No worries, hope you enjoy the package!
I still try to follow the JuliaCon21 talk.
