[Python] Why is my Winsorization code telling me it has too many arguments?

I have an array that looks like this:

[ 3.4 0. 10.6 ... -0.4 -0.4 0. ]


The array has around 13.5m values in it. I want to winsorize the top and bottom 5% to deal with outliers. This is the code I'm using:

from scipy.stats.mstats import winsorize
winsorized_array = winsorize(array, (0.05, 0.05))


However, this returns the following error message:

TypeError: winsorize() takes 1 positional argument but 2 were given
​

I've also tried the following variation:

from scipy.stats.mstats import winsorize
winsorized_array = winsorize(array, limits = [0.05, 0.05])


This returns the following error message, which doesn't make any sense to me, since as far as I can tell this is the same syntax found in the scipy documentation here:

TypeError: winsorize() got an unexpected keyword argument 'limits'
​

Does anyone know what I'm doing wrong please?
