I received this error message:

  MethodError: convert(::Type{Union{}}, ::Vector{Float32}) is ambiguous. Candidates:
    convert(::Type{T}, a::AbstractArray) where T<:Array in Base at array.jl:532
    convert(T::Type{var"#s79"} where var"#s79"<:BitArray, a::AbstractArray) in Base at bitarray.jl:577
    convert(T::Type{var"#s832"} where var"#s832"<:SparseArrays.SparseVector, m::AbstractVect

In recent versions (can't say from exactly when), there seems to be an off-by-one error in dcc.DatePickerRange. I set max_date_allowed = datetime.today().date(), but in the calendar, yesterday is the maximum date allowed. I see it in my apps, and it is also present in the first example on the DatePickerRange documentation page.

I added this test to show the issue:

Issue is in functions like this:
https://github.com/JuliaOpt/MathOptInterface.jl/blob/3f872f9edb50b1a97cb65011430a0160fd56111e/src/Utilities/cachingoptimizer.jl#L539-L557
where we need a branch to see if it is possible to query directly from the optimizer.

(This is related to JuliaPlots/Plots.jl#1706)

For example scatter(skipmissing([1.0, 2.0, missing, 1.0])) fails with Cannot convert Base.SkipMissing{Vector{Union{Missing, Float64}}} to series data for plotting.

Generally skipmissing is not required but it seems odd to see this fail.

Also I stumbled on this while trying to make a histogram, e.g.

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.)

According to the documentation you can do:

on(events(fig).keyboardbutton) do event
    if event.action in (Keyboard.press, Keyboard.repeat)
        event.button == Keyboard.left   && move_left()
        event.button == Keyboard.up     && move_up()
        event.button == Keyboard.right  && move_right()
        event.button == Keyboard.down   && move_down()
    end
    # Let the event 

In Exercises 10.1, the outer product in Take the outer product of a vector v with itself and assign it to variable cross_v should be cross product.
