I feel stupid for asking this…
Some 9 months ago, I worked with some Jupyter notebooks with plotting (using Plots; pyplot()). At that time, I had to include a command:
clibrary(:colorcet)
to make my code/plots work. (I don’t recall why I had to include this…)
Now, Julia doesn’t recognize command clibrary(:colorcet)… and the code seems to work when I remove the command. (I’m on v. 1.5.0).
Was command clibrary() just a temporary fix, that has now been included in Plots?
