How do I replace all NaN values with the mean in Numpy Use boolean indexing to replace all instances of NaN in a Numpy array with the mean Here we use the numpy isnan function to check whether a value inside the array is NaN or not and if it is we set it to the mean value The following is the syntax import numpy as np The numpy isnan will give true indexes for all the indexes where the value is nan and when combined with numpy logical not function the boolean values will be reversed So in the end we get indexes for all the elements which are not nan From the indexes we can filter out the values that are not nan and save them in another array Python3
