Docs: how to use CondaPkg from PythonCall?

[sairus7]

Docs says: https://cjdoris.github.io/PythonCall.jl/stable/pythoncall/#python-deps

If your project requires any Python packages, add a CondaPkg.toml file to your project specifying what you need. Alternatively use CondaPkg.add() to add dependencies from the REPL.

But how can I access CondaPkg itself from a project using PythonCall? I've tried CondaPkg, PythonCall.CondaPkg with no success, and had to add it separately to my project: add CondaPkg, should it be stated in docs?

If I understand your question, you can do

step 1 go to your project in terminal

cd your_project 

step 2 open julia (mac command)

%   julia  

step 3 now you are in julia repl ,

using CondaPkg

if it is not installed , REPL will prompt an installation.

after installed CondaPkg, then using CondaPkg
step 4 press"]" in the REPL to access Pkg and activate this project;

activate . 

Now you are in the project.
you can add python package with

conda add your_python_package

last step

conda resolve

then you are good to go to the pluto notebook in this project
and using these python package like this

I mean, why I need to install both PythonCall and CondaPkg, doesn't PythonCall already use CondaPkg?

That's actually something I've been wondering as well. In PyCall we can do something like this I think:

using PyCall
PyCall.Conda.add("matplotlib")

so having an equivalent for CondaPkg over here seems like it would be handy, but maybe I am misunderstanding why it is not exported in this case

[icweaver]

Oh neat, just saw this usage in another issue: PythonCall.C.CondaPkg

[cjdoris]

There's no guarantee PythonCall.C.CondaPkg won't be renamed in the future. Just add CondaPkg yourself.
