@carstenbauer, I have already used “using Random”, do I need to use “import Random” in order to use the “Base.GLOBAL\_RNG”?

Calling `Base.GLOBAL_RNG` still tries to access `GLOBAL_RNG` in the module `Base`, from which it was deprecated.

What are you actually trying to do? It might be helpful to consult the [Random](https://github.com/JuliaLang/julia/blob/a2e0b59f1cebfb6a3d800ed7d4f91464c618d18d/stdlib/Random/docs/src/index.md) docs

@nilshg, I was trying to figure it out what’s going on. Thank you.

I tested it again. This time,

```julia
using Random
Random.GLOBAL_RNG 

```

works.
