Can't load package (StatsBase) in Jupyter notebook but can in REPL

General Usage
1

I have a fresh installation of julia-1.6.5 on an ubuntu 18.04 box. I added a number of packages and in the REPL, I can

julia> using StatsBase
[ Info: Precompiling StatsBase [2913bbd2-ae8a-5f71-8c99-4fb6c76f3a91]

Success. But the same thing in a jupyter notebook (which I have to use) results in:

I am definitely using the julia-1.6.5 kernel.

Anyone know how I can fix or get around this? Am I doing something wrong?

Regarding the warnings, I have added LogExpFunctions, ChangesOfVariables, and ChainRulesCore, and loaded them (using) in the REPL too. I tried the Pkg.resolve().

2

Are you adding the packages in a local project.toml, or are they in your v1.6 toml file?

Make sure you do import Pkg; Pkg.activate(".") before adding packages and try again.

3

No, I was just adding them in the “global” environment. I am trying to make what you suggest work, but is that necessary? If so, can you tell me why? Thanks.

4

I don’t know. I wonder if IJulia is using some environment that’s different than the main one and isn’t inheriting the global environment for some reason.

I could be wrong though.

5

It definitely is inheriting because I can Pkg.add() a package from the REPL in the global environment and in the jupyter notebook the package becomes “available” (even though it can’t precompile it).

6

This seems to have worked. If anyone can help me understand, that would still be appreciated. Thank you.

Hi everyone I am having the same problem as rwgardner but the solution proposed by @pdeffebach is not working for me. Do you have any clue on how to solve this issue?
If it matters I am using DrWatson and thus a toml file.

PS: I have been using julia in the last six months, including the StatsBase package, without any problem. It arouse out of the blue today
