Description:
 def equals(self, other, equiv=duck_array_ops.array_equiv):
 """True if two Variables have the same dimensions and values; otherwise False. Variables can still be equal (like pandas objects) if they have NaN values in the same locations. This method is necessary because `v1 == v2` for Variables does element-wise comparisons (like numpy.ndarrays). """
