I’m facing error while trying to run this piece of code:

import numpy as np

from numba import njit

@njit

def cartesian_product(*arrays):

“”"

A generator function that generates the Cartesian product of multiple arrays.

“”"

# Generate the meshgrid

grids = np.meshgrid(*arrays, indexing=‘ij’)

```
# Stack the arrays together to form the Cartesian product
stacked = np.stack([grid.ravel() for grid in grids], axis=-1)
# Yield each element of the Cartesian product
for elem in stacked:
yield tuple(elem)
```

# Example usage

a = np.array([1, 2, 3])

b = np.array([4, 5])

c = np.array([6, 7, 8])

for elem in cartesian_product(a, b, c):

print(elem)
