sample(...) does not work #293

Closed FalkoSp closed 2 years ago

FalkoSp commented 3 years ago

Hi, I'm slowly following the JuliaCon21 video. The call to sample(..) fails.

(I had another issue before that it wasn't found in a Pluto notebook. I'll try to reproduce that when I have it running without Pluto.)

using Soss#: @model
using MeasureTheory#: Normal, HalfNormal, Chain
using Base.Iterators#: take
using Pkg: status
using UnicodePlots: lineplot, lineplot!
using SampleChainsDynamicHMC#: dynamichmc

mc_init4 = @model begin
    x ~ Normal(0.0, 1.0)
    return (x=x,)
end

mc_step4 = @model p, s begin
    x ~ Normal(s.x + p.Δμ, p.σ)
    return (x = x,)
end

m4 = @model begin
    Δμ ~ Normal()
    σ ~ HalfNormal()
    p = (; Δμ, σ)
    mc4 ~ Chain(mc_init4()) do s mc_step4(p=p, s=s) end
    return mc4
end

gen4(n) = map(state -> state.x, collect(take(rand(m4()), n)))

p = lineplot(collect(1:100), gen4(100), 
             width=80, height=35,
             ylim=[-50, 50]);
for i in 1:4
    global p = lineplot!(p, gen4(100))
end

display(p)

some_data = collect(take(rand(m4()), 500));
post = m4() | (mc4 = some_data,)

sample(post, dynamichmc())

The call to sample in the last line gives

cscherrer commented 3 years ago

Hi, sorry for the delay on this. This is really strange, especially since StructArrays in included as a dependency for SampleChainsDynamicHMC. Does the package manager otherwise seem happy? Have you tried ]resolve?

cscherrer commented 3 years ago

Oh, I guess the error is coming from TupleVectors, but StructArrays is a dependency there too. Can you do status -m?

FalkoSp commented 3 years ago

Btw, SampleChainsDynamicHMC gives a warning.

Ah, and when I directly include the code from https://github.com/cscherrer/Soss.jl/blob/master/src/samplechains/dynamichmc.jl, it works completely fine. Even in Pluto. I don't see why.

begin
using Random

using SampleChainsDynamicHMC:DynamicHMCConfig

function sample(rng::AbstractRNG, 
    m,#::ConditionalModel,
    config::DynamicHMCConfig, 
    nsamples::Int=1000,
    nchains::Int=4)

    ℓ(x) = Soss.logdensity(m, x)
    tr = xform(m)

    chains = newchain(rng, nchains, config, ℓ, tr)
    sample!(chains, nsamples - 1)
    return chains
end

function sample(
    m,#::ConditionalModel,
    config::DynamicHMCConfig, 
    nsamples::Int=1000,
    nchains::Int=4)

    sample(Random.GLOBAL_RNG, m, config, nsamples, nchains)
end
end

Hi @FalkoSp , I just realized this hasn't been resolved. Could you update your packages and try again? TupleVectors is currently at 0.1.2, so it's best to make sure you can use that release

cscherrer commented 2 years ago

@sethaxen may have fixed the problem in https://github.com/cscherrer/Soss.jl/pull/300

@FalkoSp @gzagatti could you try again with the latest version please?

sethaxen commented 2 years ago

Yes, that should fix the problem. I'd seen the error message for a while, but it caused Pluto to completely fail, which is what led me to fix it. Now I'm using Soss in Pluto with no problems.

cscherrer commented 2 years ago

This is great!!!

@FalkoSp and @gzagatti, if you can confirm when you have a chance, we can close this issue :)

FalkoSp commented 2 years ago

Thank you @sethaxen, thank you @cscherrer - works now!
