I’ve tried using `PythonCall` + `CondaPkg` from pluto notebooks. Everything basically works fine: packages get installed and imported, plots displayed:

The packages themselves seem to exist in a single copy in `~/.julia/scratchspaces` even if I create multiple notebooks that use matplotlib - they don’t duplicate for each notebook. I don’t really understand how this works though…

Still, new directories in `/tmp` are created for each new notebook run. They are created by Pluto, but Pluto only puts Project & Manifest files there that don’t take any noticeable space. “Apparent sizes” of those temporary dirs (speicifcally, the .CondaPkg subdirs) are 1 Gb, but actually most of the files are hardlinks I assume: each dir adds 150 Mb to disk usage, not 1 Gb. Is it possible to remove this duplication?
