Expected behavior
cupynumeric.full((2, 2), [1, 2]) outputs the correct result.
Observed behavior
cupynumeric.full((2, 2), [1, 2]) causes the ValueError: Filled value array size is not equal to 1.
Example code or instructions
import numpy as np
import cupynumeric as cp
print(np.full((2, 2), [1, 2]))
print(cp.full((2, 2), [1, 2]))Stack traceback or browser console output
