I have been trying to use the Turing.jl package,  
MacOS v10.15,

I successfully added the package Turing v0.7.0, with dependent packages Zygote v0.3.0, IRTools v0.3.0

but when executing:  
using Turing

I get precompile error:  
**[Info:** Precompiling Turing [fce5fe82-541a-59a6-adf8-730c64b5f9a0]

in expression starting at /Users/martinwatts/.julia/packages/Zygote/kTgN8/src/Zygote.jl:24

Cause of the error is that Zygote package tries to import IRTools:Argument but IRTools does not export Argument

Any known fixes to this problem?

Try updating `Turing`.

this set gave a different precompile failure but still at the interface between the Zygote and IRTools.

I assume there must be a working set of these packages.

The latest release should be v0.7.2. Can you try `] add Turing`?

UPDATE: sorry I didn’t see the latest reply.

I tried a fresh installation of Julia v1.2.0 on macOS and the precompilation works. Can you try to remove Zygote and Turing and `] add Turing` again?

Thanks, it is now precompiling and I am able to execute the Getting Started example.
