如何有效地将numpy.int8数组就地转换为值移位的numpy.uint8数组？

import numpy as np

# 创建一个int8数组
int8_array = np.array([-1, 0, 1, 2, 3], dtype=np.int8)

# 使用view方法将int8数组转换为uint8数组
uint8_array = int8_array.view(np.uint8)

print("Int8 array:", int8_array)
print("Uint8 array:", uint8_array)

Int8 array: [-1  0  1  2  3]
Uint8 array: [255 0 1 2 3]
