>>> import numpy as np
>>> import numpy.ma as ma
>>> a = ma.masked_equal([[1,2],[3,4]], 2)
>>> a
masked_array(
  data=[[1, --],
        [3, 4]],
  mask=[[False,  True],
        [False, False]],
  fill_value=2)
>>> ma.getdata(a)
array([[1, 2],
       [3, 4]])

Equivalently use the MaskedArray data attribute.

>>> a.data
array([[1, 2],
       [3, 4]])
