Upgrade to v0.6

[ChrisRackauckas]

Julia v0.6 is the current release. It seems there's no tests on v0.6, and when I try using Turing on v0.6 it stalls.

Yes, we plan to work on that. There is an issue preventing us from using Julia 0.6 at the moment, see

#173

JuliaLang/METADATA.jl#10646 (comment)

[yebai]

I made some progresses on this issue. Now Turing can load within Julia 0.6, however, some tests are currently broken (Pkg.test("Turing")) -- the issue seems related to a change on the Julia side (JuliaLang/julia#21356).

Ps. the code is in #341

See also JuliaLang/julia#19774

Also in the docs: https://docs.julialang.org/en/stable/manual/methods/#Redefining-Methods-1

If you (re)define a method f, it can't be called directly in the current runtime, you need to use invokelatest(f, args...). Note that there's a (potential?) performance penalty associated with this, because inference can't happen with invokelatest.

I found that if we do the model evaluation and calling sample(), Julia doesn't throw the error. E.g.

modelf = gdemo(x)
sample(modelf, alg)

From https://docs.julialang.org/en/stable/manual/methods/#Redefining-Methods-1

But neither you, nor any of your callers, nor the functions they call, or etc. can call this new method definition!

Any news on this issue ?
Do we have a list of the issues/tests yet solved ?

[xukai92]

@emilemathieu Please see #341

In short Turing can be used in Julia 0.6 in this PR, and we are adapting the new co-routine and fixing some minor issues.

@xukai92 let's try to merge the PR this week - I will make an effort of fixing coroutine issue; Could you fix other known issues?

As of now, all tests in #341 are passing on Julia 0.6.

@xukai92 Could you fix remaining warnings in the branch?

For the warnings you can just install Femtocleaner
