Cannot import TwoSlopeNorm

Hi I was trying to run a plotting code after about 6 months, and some of the modules/functions cannot be imported anymore. I checked online and saw the following example in the matplotlib page: matplotlib.colors.TwoSlopeNorm — Matplotlib 3.5.3 documentation
It seems to give error ‘module’ object has no attribute ‘TwoSlopeNorm’

I would appreciate any directions on solving this error.
Thank you and best regards,

import matplotlib.colors as mcolors
offset = mcolors.TwoSlopeNorm(vmin=-4000.,
vcenter=0., vmax=10000)
data = [-4000., -2000., 0., 2500., 5000., 7500., 10000.]
array([0., 0.25, 0.5, 0.625, 0.75, 0.875, 1.0])

What version of Matplotlib are you using? You have a version that does not yet include TwoSlopeNorm

Thank you, I used a recent version of Matplotlib and it works fine now.
