Hi,  
I installed Julia 1.6, and it runs perfectly with several packages. I then ran Jupyter-lab, and tried

```julia
using Plots

```

in a Julia 1.6 environment. Jupyter-lab then tried to compile `Plots`. Why would it do that since it was already compile (yes, I did a `build IJulia` in Atom). Here is what I see in Jupyter-lab:

```julia

Any help is appreciated. Thanks!

Maybe you are running in a different environment? use `] st` to print out the package status and the current environment in both Jupyter and the REPL. (You tried the REPL, not just Atom, right?)

You are correct! I did a status both in the REPL of Atom and via the Terminal and get the same version 0.15.1 for Turing. In Jupyter, using Julia 1.6, I get Turing version 0.14.3 !!

What could I be doing wrong? I did a build of IJulia inside Atom. Of course, I could completely reinstall Atom, but seems like overkill. I obviously did things correctly under ~/.julia; otherwise, I would not be able to get the packges to be correct in the Atom REPL. Any advice? Thanks!

I usually put something like this at the start of every Jupyter notebook:

```julia
ENV["COLUMNS"] = 200 # wide output is OK
ENV["LINES"] = 15; # but we do not want it to be overly tall
cd(@ __DIR__ )
using Pkg
Pkg.activate(".")
Pkg.status()

```

This makes it really obvious which environment I’m using and what’s inside.

That’s a neat trick, I’m gonna steal that 😉

Yes, I will adopt this trick as well. Thanks. And my problem is solved. The directory I started Jupyter from had a Project.toml and a Manifest file. I simply removed `Pkg.activate(".")` and changed the name of the `project.toml` file, and now my environment matches that of Julia 1.6 .
