[Python] TypeError: Cannot interpret '1' as a data type Python

I get the error "TypeError: Cannot interpret '1' as a data type" For the following code chunk,

for j in range (T):
V_j=V[:,:,j]
'Check positive definiteness using Cholesky decomposition.'
'Also check the reciprocal condition number.'
try:
np.linalg.cholesky(V_j)
except np.linalg.LinAlgError:
Flag = 1
break
--> rcond = 1 / np.linalg.cond(V_j)
if rcond < 1e-15:
Flag = 1
break




should I change 1 in rcond = 1 / np.linalg.cond(V_j) for np.zeros(shape, dtype=float, order='C')?

np.zeros(shape, dtype=float, order='C')
