Apart from cloning, an easy way of using the package is the following:

1 - Add the registry AINJuliaRegistry

2 - Switch into "package mode" with ] and add the package with

add GPLVMplusData

Example

using PyPlot # must be independently installed, other packages can be used instead
X = GPLVMplusData.loadducks();
pcolor(rot180(reshape(X[:,1],128,128)))

Load subsampled images:

using PyPlot # must be independently installed, other packages can be used instead
X = GPLVMplusData.loadducks(;every=2); # subsamble images to 64×64.
pcolor(rot180(reshape(X[:,1],64,64)))

X = GPLVMplusData.loadducks(;every=3); # subsamble images to 43×43.
pcolor(rot180(reshape(X[:,1],43,43)))

X = GPLVMplusData.loadducks(;every = 4); # subsamble images to 32×32.
pcolor(rot180(reshape(X[:,1],32,32)))
