sqrtm() function returns nan

I have a 512 x 512 matrix Avg and it has many zero and non-zero values. Now I want an inplace element-wise square root of the matrix. This is part of my code

import numpy as np
from scipy.linalg import sqrtm

Avg = sqrtm(Avg)
np.savetxt('Avg.txt', Avg)

But, the output is all nan and it says that the matrix is singular and may not have a square root.

You say you want an element-wise square root. That's np.sqrt(), not scipy.linalg.sqrtm():

Avg = np.sqrt(Avg)
