ARDESPOT problem model error

[Etwari3]

Hello,

I got this message running a continuous POMDP - "MethodError: Cannot convert an object of type Vector{Float64} to an object of type Int64".

Can you please help fix it?

Thank you.

Hi @Etwari3, this error is likely occurring because your observation function is returning a single observation rather than a distribution.

The following observation function may get things to run as intended:

function POMDPs.observation(m::PipeCS, a::Int, sp::Float64)
    n = 15
    _s = round(Int, sp*100)
    return POMDPTools.Uniform(max(_s-n, 0):min(_s+n, 95))
end

I'm using POMDPTools for this, but you can use the older POMDPModelTools if need be.

Thank you.
