'list' object has no attribute 'ndim'

Hello,

I am trying to apply the following simple code

wquantiles.median([1,2,3,4,5], weights = [0.15, 0.1, 0.2, 0.3, 0.25])

Unfortunately, I have the following error:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

     78     if nd == 0:
     79         TypeError("data must have at least one dimension")

AttributeError: 'list' object has no attribute 'ndim'

Could you help me please? I could not find any documentation.

Try to convert the input lists to numpy arrays first:
wquantiles.median(numpy.array([1,2,3,4,5]), weights = numpy.array([0.15, 0.1, 0.2, 0.3, 0.25]))
If it does not work please let me know.
