numpy not found

while i try to run the below code it is showing numpy module is not found.
so please make sure to update the numpy module in the server.

import numpy as np

for _ in range(int(input())):
n = int(input())
a =
for x in range(n):
a.append(list(map(int,input().split())))

a=np.array(a)
sums = [a.trace()]
for x in range(1,n):
    print(a[0:n-x,x:n])
    sums.append(a[0:n-x,x:n].trace())
    print(a[x:n,0:n-x])
    sums.append(a[x:n,0:n-x].trace())
print(max(sums))

Hey @sanjeevi86, yes numpy is currently not installed on the online judge. We will add it in some time.
