Error while passing multi dimensional array for encryption?

I was trying out your script in https://iamtrask.github.io/2017/03/17/safe-ai/ with multi dimensional arrays.

x = np.array([[0,1,2,5],
              [4,5,9,10],
              [8,3,7,1 ]])

m = len(x)
n = m
w = 16
S = generate_key(w,m,n)

T=get_T(n)
c,S=encrypt_via_switch(x,w,m,n,T)
decrypt(c,S,w)

but I am getting this error

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

though your example in the article works fine.

I tried the same code in the article, but I got error with the shape of the matrix . It is part 6 when you encrypt the XOR ANN. The code in the article need the methods ( innerProd, .. and the others) kindly if you could provide us with the full code. Thank you.

Definitions of innerProd and innerProdClient are missing. Could you please kindly provide?
