Random seed gives the same value when importing Salabim

I am trying to generate a random seed with the package random. However, I keep getting the same value every time I run the code. I saw that if I don't import salabim then the seed generated is always a different number.

This is my code:

import salabim as sim  # Without this import the seed generated is always different
import random

RandomSeed = True

#Random Seed
if RandomSeed:
    seed = random.randint(1000000, 9999999) #Random number of 7 digits
    randomstream = random.Random(seed)
else:
    randomstream = None

print(seed)

Does anyone know what is causing this?

Thanks a lot!
