python - 无法使用 numpy load() 加载数组

Question

我无法从二进制文件加载数组。我做错了什么？

pic = imread('headey-640.bmp')
save('test.in.npy', pic)
f = open('test.in.npy','r')
A = load(f)

---------------------------------------------------------------------------
ValueError: total size of new array must be unchanged

Answer 1

您必须以二进制模式打开您的文件:

import numpy as np

x = np.array([1,2,3])
np.save("test.npy", x)

with open("test.npy", "rb") as npy:
    a = np.load(npy)
