LoadError on "using" statement in Julia 0.6 #10

Closed gondsm closed 7 years ago

gondsm commented 7 years ago

Hello! I am trying to get the MCVI solver to work. So far I haven't had much success. As soon as I load the package, I get:

julia> using POMDPs

julia> using MCVI

WARNING: deprecated syntax "typealias Reward Float64" at /home/vsantos/.julia/v0.6/MCVI/src/MCVI.jl:10.
Use "const Reward = Float64" instead.

This is on the latest version, of course. Is this some sort of incompatibility with Julia 0.6?

Am I perhaps doing something wrong...?

Hi @gondsm, I think you must somehow have an old version of the code. What is the output of

julia> cd(Pkg.dir("MCVI")); run(`git pull`)

Hello @zsunberg, thanks for the reply!

Apparently when I said

This is on the latest version, of course.

I was a bit... premature. I thought I had updated everything recently, but "recently" meant some time ago, possibly around the time Julia 0.6 first came out, which kind of feels like yesterday. Time flies! Turns out updating the repo (using your command, in fact!) instantly fixed the problem.

Sorry for the unnecessary issue, closing it now, and many thanks once again!
