I’m trying to build a simple model and I’m experiencing some errors that I’m unable to debug. Here’s the code I’m running:
```julia
using Agents
using AgentsPlots
using Distributions
using LightGraphs
mutable struct EmployerAgent <: AbstractAgent
id::Int
pos::Int
compliant::Bool
end
function initialize(
num_agents = 100,
graph_edges = 50,
p_compliance = 0.9,
p_inv_net = 0.03,
p_inv_solo = 0.01
)
space = GraphSpace(SimpleGraph(num_agents, graph_edges))
properties = Dict(
:p_compliance => Bernoulli(p_compliance),
:p_inv_net => Bernoulli(p_inv_net),
:p_inv_solo => Bernoulli(p_inv_solo)
)
model = ABM(EmployerAgent, space; properties = properties)
for n in 1:num_agents
agent = EmployerAgent(n, n, rand(model.properties[:p_compliance]))
add_agent_single!(agent, model)
end
return model
end;
agent_color(x) = x[1].compliant == 0 ? :red : :green
model = initialize()
plotabm(model; ac=agent_color)
```
Most of the time that I call `plotabm` it works, but every 4th or 5th call (seemingly at random) it returns this:
```julia
AssertionError: length(node_weights) == n

It appears that the error is in the plot generation so I’m not sure if this is an AgentsPlots.jl issue or if my code would be expected to randomly break like this for some reason (due to my own error).
Furthermore, after loading `InteractiveChaos` I don’t have access to the `interactive_abm` function:
```julia
using InteractiveChaos
?interactive_abm()
search: interactive_poincaresos interactive_orbitdiagram InteractiveChaos
Couldn't find interactive_abm
Perhaps you meant InteractiveChaos
```

I’ve read through your ABM code and it seems fine to me. I think this is a problem with `AgentsPlots`.

I was able to replicate this. However, it’s possible to access `interactive_orbitdiagram` but not `interactive_abm`. The docstring for `interactive_abm` seems to exist (see [https://github.com/JuliaDynamics/InteractiveChaos.jl/blob/master/src/agents/agents.jl](https://github.com/JuliaDynamics/InteractiveChaos.jl/blob/master/src/agents/agents.jl) ) and should work as expected.

Hi, just saw this. Before going into the context, @mthelm85 if you have a question or problem with a Julia package (at least for those in JuliaDynamics), you are more likely to get help faster by simply posting this directly on the appropriate GitHub page.
* * *
Your first problem should be discussed in [https://github.com/JuliaDynamics/AgentsPlots.jl](https://github.com/JuliaDynamics/AgentsPlots.jl) , please open an issue. The main point is to see whether this problem is truly from `AgentsPlots` and not from the graph plot recipe of Plots.jl.
* * *
Your second problem comes because (I believe) you are not in the appropriate version, see here: [https://github.com/JuliaDynamics/InteractiveChaos.jl/issues/9](https://github.com/JuliaDynamics/InteractiveChaos.jl/issues/9)
