Default is True New in version 1 13 nanint float optional Value to be used to fill NaN values If no value is passed then NaN values will be replaced with 0 0 New in version 1 17 posinfint float optional Value to be used to fill positive infinity values Numpy nan to num NumPy v1 21 Manual. Example 1 In this example we created an array of imaginary numbers with the help of np nan and np inf The shape of the array is defined by the shape attribute and the dimension of the array is defined by ndim Now we will use the posinf parameter to replace np inf with the 999999 value Python3 import numpy as np To replace nan value with zero you will need to use the np nan to num function This function takes an array and returns a new array with all nan values replaced by zeroes It also has an optional parameter that can be used to specify the replacement value for nan values instead of using zero which can be useful in certain situations
