Simple example doesn't work about klara.jl HOT 4 CLOSED

Dear Viral,

Thanks...I would have posted a stacktrace, but I've no idea how
(backtrace() gives me a two pointer array) - I've tried googling but I
haven't found how as yet.

Best
Simon

This is the stacktrace:

Sorry, but I'm not in a position to help you right now being away from my computer.

You may have better luck by trying : res = run(mymodel * RWM(0.1), steps=1000, burnin=100)

Or by using a prior version of the package because I may have broken things with my last commits.

Thanks, but this still throws the same error:

julia> res = run(mymodel * RWM(0.1), steps=1000, burnin=100)
ERROR: no method MCMCChain(Dict{Any,Any},Array{Float64,1},MCMCTask,Float64)
 in run at /home/simon/.julia/MCMC/src/runners/run.jl:17

julia> res = mymodel * RWM(0.1) * (100:1000) 
ERROR: no method MCMCChain(Dict{Any,Any},Array{Float64,1},MCMCTask,Float64)
 in run at /home/simon/.julia/MCMC/src/runners/run.jl:17
 in * at operators.jl:47

In MCMC.jl there is an outer constructor:

MCMCChain(s::Dict, t::MCMCTask, ti::Float64) = MCMCChain(s, Float64[], t, ti)

but this doesn't seem to correspond to the definition of MCMCChain:

type MCMCChain
    samples::Dict
    task::MCMCTask
    runTime::Float64
    misc::Dict               # dict for storing runner specific variables
end

from klara.jl.

@sdwfrost, the serial MCMC routines should work now (I tested the example you mentioned above) - just reverted back to the initial MCMCChain type definition, prior to the breakage caused by the unfinished sequential MCMC coding.
