M_inverse = numpy.linalg.inv(M)

#Or use the exponent notation, which is also understood by numpy
M_inverse = M**(-1)

Inverse matrix python numpy

from numpy.linalg import inv
a = np.array([[1., 2.], [3., 4.]])
ainv = inv(a)
np.allclose(np.dot(a, ainv), np.eye(2))
True
np.allclose(np.dot(ainv, a), np.eye(2))
True
