Error in NTT.py

[rkarn]

I created the profile folder and run "python3 Test_Ctxt.py". I get following error. Can you please help?

Did you get any solution to this @rkarn ? Struggling with the same

I saw a solution to resolve this error, add a line in ntt.py：

def orderReverse(self, poly, N_bit):
        _poly = list(poly)
        _poly = list(np.array(_poly).astype(int))
        for i, coeff in enumerate(_poly):
            rev_i = self.bitReverse(i, N_bit)
            if rev_i > i:
                coeff ^= _poly[rev_i]
                _poly[rev_i] ^= coeff
                coeff ^= _poly[rev_i]
                _poly[i] = coeff
        return _poly

In this code , _poly = list(np.array(_poly).astype(int)) was added, but I don't know why and is it right. You can try it, and the code runs correctly in small parameter.
