2、错误原因

      python语言中的numpy包，字符串数组不能交换，不然会报错

import numpy as np;

A = np.all([[1,2,3,4],[5,6,7,8]], axis=0);
B = np.array([1,4,6,8.9]);
C = np.array([1,234,5343], dtype=np.int64);
D = C.byteswap(inplace=True);
E = list(map(hex,A));
F = np.array(['yh','ui','ce','dh']);
print(A);
print(B);
print(B.astype(int));
print(C);
print(D);
print(E);
print(F.byteswap());

3、解决办法

      在定义变量F时，调用np.array()，数组中的元素不能是字符串类型

import numpy as np;

A = np.all([[1,2,3,4],[5,6,7,8]], axis=0);
B = np.array([1,4,6,8.9]);
C = np.array([1,234,5343], dtype=np.int64);
D = C.byteswap(inplace=True);
E = list(map(hex,A));
F = np.array([23,45,67,32]);
print(A);
print(B);
print(B.astype(int));
print(C);
print(D);
print(E);
print(F.byteswap());
