Why LSTM give different output despite I use the same code?

Question

I ran code from this link (for predict price of sp500) and I found that output (predicted price) are not the same when I ran the code for second and third time. They are not even close sometimes. I just know the basic knowledge of LSTM and never code it before.

Answer 1

It is better to seed the inbuilt pseudo-random number generator. Kindly try using the following:

import random
import numpy as np
from tensorflow import set_random_seed

random.seed(10)

np.random.seed(10)

set_random_seed(10)
