I would like to make all possible combinations with elements from 5 different arrays.

However, when I ran my codes, the error showed the number was too high. Would there be a solution to this problem?

Here is my code:

```
import numpy as np
a=np.arange(1000000000)
b=np.arange(2000000000)
c=np.arange(2000000000)
d=np.arange(1000000000)
e=np.arange(1000000000)
from itertools import product
iterables = [a,b,c,d,e]
total_combi_index=[]
for t in product(*iterables):
total_combi_index.append(t)
```
