ERROR: ArgumentError: the length of each axis must match the corresponding size of data

[mdhe1248]

I was just following the examples in the Images document.
I obtained the error when I used AxisArray:

julia> using Images, Unitful, AxisArrays
julia> using Unitful: mm, s

julia> AxisArray(rand(256,256,100,50), (:x, :y, :z, :time), (0.4mm, 0.4mm, 1mm, 2s))

Try Pkg.checkout("Unitful"). In Julia 0.5, it's error-prone to construct ranges of Unitful objects, so recent work in Unitful now exploits the Ranges.jl package to try to help resolve these problems. In Julia 0.6, ranges have been redesigned (JuliaLang/julia#18777) and should make this much easier.

@ajkeller34, maybe we could get a new tag?

[ajkeller34]

I'm eager to tag a new release, but have been holding back since julia 0.6 is so close to stabilizing and it would be nice to see the next release work properly on 0.6.0. I can tag one if its urgent though.

[timholy]

Not urgent, so if you want to wait that's fine. The argument to tag is that this bug has already been reported twice.

Have you set up attobot? It makes tagging easier. I'm starting to tag packages sometimes after single commits (depends on the commit, of course).

[timholy]

Fixed by the new Unitful tags. Thanks a ton, @ajkeller34!
