icml2020_ipft's Issues

Environment Setup

I am having trouble setting up the environment. After cloning the repository, I start the Julia REPL from the top folder and enter:

using Pkg
Pkg.add("POMDPs")
using POMDPs
POMDPs.add_registry()
Pkg.activate(".") # this activates the environment we provide, when starting Julia in the correct folder
Pkg.instantiate()

However, there is an issue in the instantiation step.

julia> Pkg.instantiate()
┌ Warning: The active manifest file is an older format with no julia version entry. Dependencies may have been resolved with a different julia version.
└ @ ~/icml2020_ipft/Manifest.toml:0
Precompiling project...
  ✓ POMDPs
  ✗ POMDPModels
  ✗ POMDPSimulators
  ✗ LaserTag
  ✗ MCTS
  ✗ BasicPOMCP
  ✗ IPFT
  ✗ POMCPOW
  ✗ SunbergTypes
  9 dependencies successfully precompiled in 60 seconds (118 already precompiled, 32 skipped during auto due to previous errors)
  1 dependency precompiled but a different version is currently loaded. Restart julia to access the new version
  8 dependencies errored. To see a full report either run `import Pkg; Pkg.precompile()` or load the packages

After running Pkg.precompile() and Pkg.build() on the suggested packages Pkg.instantiate() is able to finish. But then when trying to run julia --project=. Experiments/ld_table.jl the following error appears ERROR: LoadError: UndefVarError: promote_eltype_op not defined

It seems this is a byproduct (related to the previous issue that was already filed) of IPFT not being its own package. I'm not sure if there has been any further discussion on this.

Consider making IPFT.jl a Julia package

We would love to have IPFTSolver available to everyone in the POMDPs.jl ecosystem. Would it be possible for you to extract the solver and discuss requirements for adding it to the JuliaPOMDP Registry?
