Pkg.activate(temp=true)

using MLJBase, OutlierDetectionPython

X = (a = rand(10), b = rand(10))
detector = OutlierDetectionPython.CDDetector()

mach = machine(detector, X)
fit!(mach)

FYI: You can add generic interface tests using MLJTestInterface.jl, along the lines of this example. These tests would have caught this error.

Looks like I forgot to add this detector to the tests (https://github.com/OutlierDetectionJL/OutlierDetectionPython.jl/blob/master/test/runtests.jl). I'll have a look.
