Environment Setup about icml2020_ipft HOT 3 OPEN

Is it possible that you are using a Julia version newer than Julia 1.2? The code was only tested on Julia 1.2.

Apart from that the environment setup is probably outdated, since the POMDPs packages have moved from the SISL registry to the general registry. So it should be enough to do

using Pkg
Pkg.activate(".")
Pkg.instantiate()

For me it works in Julia 1.2 and I can run julia --project=. Experiments/ld_table.jl.

Can you test if that works for you on Julia 1.2? Then I will update the readme.

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.

Unfortunately, I couldn't find the time yet to make a proper package out of this that works with current Julia versions. But I will try to find the time.

Hey,
I'm trying to setup your enviroment at Julia 1.2.0. Got banch of errors and can't run any of your scripts.
After I did "Pkg.instantiate()" I got warning and errors (there're mentioned in the end of my comment).

Than, I tried to run ld_table.jl, and got errors:
ERROR: LoadError: LoadError: LoadError: LoadError: UndefVarError: n_observations not defined

from icml2020_ipft.

Is it possible that you deleted the Manifest.toml file or that it somehow wasn't used for instantiation? The error message ERROR: LoadError: LoadError: LoadError: LoadError: UndefVarError: n_observations not defined sounds like you are using a more recent version of POMDPs.jl (the n_observations interface was removed from POMDPs.jl at some point, making POMDPModelTools fail to compile for you).
