Assume you have two functions like these:
import numpy as np
def function_1(seed):
res = []
np.random.seed(seed)
for i in range(10):
res.append(np.random.rand())
return res
def function_2(seed):
res = []
np.random.seed(seed)
for i in range(10):
a = np.random.rand() # necessary!
res.append(np.random.rand())
return res
They are basically the same, just that in function_2 you are required to generate an additional random number for each run of the for-loop.
Now,
x = function_1(1)
y = function_2(1)
x == y
>>> False
However, you need to make sure that the returned res is identical for both functions. Is there a better way than changing function_1 to the following?
def function_3(seed):
res = []
np.random.seed(seed)
for i in range(10):
np.random.rand()
res.append(np.random.rand())
return res
Then,
z = function_3(1)
y == z
>>> True
