So – I understand the role of Pkg.instantiate [I think], but I need to know which Project.toml and Manifest.toml file is used.
It seems like when I run Jupyter notebooks, then Julia defaults to looking in the directory where the notebook is located, and not in the location of the global Project.toml and Manifest.toml files [which I thought it would].
I thought that if I had not used Pkg.activate("...") to specify a location for the Project.toml and Manifest.toml files, then the global files would be used. But it seems to not be so.
