hey all, I tried to run SolveMDP.jl this code in julia1.1.1 on wsl ubuntu. I have installed all packages required but I had such an error:: “”–ERROR: LoadError: LoadError: UndefVarError: n_actions not defined Stacktrace: [1] getproperty(::Module, ::Symbol) at ./sysimg.jl:13 [2] top-level scope …

[image] Sukera: provide I don’t have such a minimal example. Project is prettty complex. MDP I end up with given error when SolveMDP.jl is runned

relevant part of the code is “# Define necessary functions for HCAS MDP POMDPs.actionindex(::HCAS_MDP, a::actType) = a + 1 POMDPs.actions(mdp::HCAS_MDP) = ACTIONS POMDPs.discount(mdp::HCAS_MDP) = mdp.discount_factor POMDPs.n_actions(::HCAS_MDP) = length(ACTIONS)” which is a part from h_CAS.j…

I think an MWE is quite simple in this case: julia> using POMDPs julia> POMDPs.n_actions ERROR: UndefVarError: n_actions not defined Stacktrace: [1] getproperty(x::Module, f::Symbol) @ Base .\Base.jl:35 [2] top-level scope @ REPL[16]:100: I don’t know what the POMDPs package is or does, …

There doesn’t seem to be any Project.toml (where package dependencies are recorded) or Manifest.toml (where versions of used dependencies are recorded) present in that repo. I agree with @nilshg - make sure you have the versions of the packages used by the original author of that paper installed. It…

How can I remove all packages and reinstall ?

Thank you all! removing and reinstalling all packages worked for that error. Now I have different kind of error "ERROR: LoadError: ProcessExitedException() Stacktrace: [1] worker_from_id(::Distributed.ProcessGroup, ::Int64) at /buildworker/worker/package_linux64/build/usr/share/julia/stdlib/v1.1/…

Worker 3 terminated.ERROR: LoadError: ProcessExitedException() Stacktrace: [1] try_yieldto(::typeof(Base.ensure_rescheduled), ::Base.RefValue{Task}) at ./event.jl:196 [2] wait() at ./event.jl:255 [3] wait(::Condition) at ./event.jl:46 [4] take_buffered(::Channel{Any}) at ./channels.jl:362 [5]…

Again, can you post the code that leads to this error? While having an error message is useful, not being able to investigate the code leading to it is detrimental to getting help. Purely from the error, it seems like one of the worker processes used by Distributed is crashing, leading to the error.…
