Hi all!,

Just want to share with the team some details I've been experiencing while I executed notebooks from command line using a yaml file.

First, let me show my case. I've bee parametrizing different notebooks to isolate data wranlging processes. To do it, I needed to use lists of dictionaries to specifiy keys describing my data, such as area or paths where some files were stored. As all

@simonbyrne noticed that the Gallery/Tutorial is slow to load. we should think about breaking it up into sub-pages, or using SVG instead of SVGJS, or ...

This issue will be used to track common interface option handling. This is a constant time factor so it's not the biggest deal, but I feel that we can improve some applications by reducing common latency here.

We have a decision to make about what to do if a user writes the following:

model = Model()
@variable(model, x[1:2] in MOI.Integer())

Should we

• (a) throw a nice error message because MOI.Integer is a scalar-set and x is a vector; or
• (b) broadcast the scalar set over the vector.

Either case needs a method like:

function build_variable(
    _error::Functio

The documentation states that

Plots offers shorthands like png(fn), etc.

However, it appears that png() is the only convenience function that is exported, which is confusing for users trying to do pdf(fn).

I assume the intention is to export these functions? If not, having to

in a jupyter notebook with my firefox browser, ctrl-shift-"-" should split a cell – but it does nothing.

Readme, re: eagermode is out of date

I found that function mod2pi is not implemented yet, but mod works. Is there any list of implemented functions? Minimal working example is:

using Zygote

# This is working
gradient(x -> mod(x, 2pi), 1.)

# This is not
gradient(x -> mod2pi(x), 1.)

From alan-turing-institute/MLJBase.jl#68:

This doesn't work:

@mlj_model mutable struct Bar
    a::Int = -1::(_ > -2)
end

But this does:

@mlj_model mutable struct Bar
    a::Int = (-)(1)::(_ > -2)
end

This needs to be documented in MLJ/docs/src/adding_models_for_general_use and MLJ/docs/src/quick_start_guide_to_adding_models

We still need docstrings for:

• Fminbox
• NewtonTrustRegion
• SimulatedAnnealing
• ParticleSwarm
• NelderMead

The other doc strings should be plenty inspiration if you're in doubt of what a doc string should contain for these types/constructors.

In particular, the default rotation speed is not very good. Could we slow down the rotation speed by default? It is hard to interact otherwise.

I was trying to use the Julia: Execute Code Cell Command, but I didn't know what was the delimiter for a cell. Finally, I found it, but It would be nice to have a comment about it :).

It would be handy for all edge operations to have both f(g, e) and f(g, src(e), dst(e)) defined by default on abstract graphs

Hi there. It's my first day coding & I really appreciate this resource and I find it more or less easy to follow. However, I would recommend either providing a link to a glossary or simply having a glossary available for absolute beginners to explain terminology such as those referring to the various data types & examples given. Just to make the language a bit more accessible.

I'm enjoying

Add a section to the README that discusses the tiers of support, re. the recent Julia update to the README by @ViralBShah.
