如何将numpy数组中的id值更改为带有字典的字符串numpy数组

import numpy as np

arr = np.array([1, 2, 3, 4, 5])

id_dict = {1: 'apple', 2: 'banana', 3: 'orange', 4: 'grape', 5: 'watermelon'}

str_arr = np.vectorize(id_dict.get)(arr)

print(str_arr)

import numpy as np

arr = np.array([1, 2, 3, 4, 5])
id_dict = {1: 'apple', 2: 'banana', 3: 'orange', 4: 'grape', 5: 'watermelon'}
str_arr = np.vectorize(id_dict.get)(arr)

print(str_arr)
