Julia is best install via JuliaUp though

I think, we are trying to find an environment suitable for both Python and Julia. Do you know if any Julia features are not available if it is installed via conda? It does install the latest version.

If it's just redistributing the official binary it's fine, I'm worried it's linking to anything in conda. And I suppose another worry is if it would be maintained later.

We already depend on CondaPkg.jl ;-)

yeah so I'm still not sure if it's built from source by Conda or not -- we have the same problem with Linux distributions, basically they would compile and not test Julia and users would then run into weird problems some times.

Depending on CondaPkg.jl is fine I meant to say one can worry if the Julia in conda-forge will be maintained or not.
