在python中加载matlab文件时删除keys()

Question

我正在尝试用python加载一个matlab文件，我已经写了以下几行：

import numpy as np
import scipy.io as spio
f = np.load('adj_data.npy',allow_pickle = True)
array1 = np.array(f)
print(array1)
print(type(array1))

运行此代码后，我得到以下结果：

如何删除数组的第一部分或matlab数组的键((部分：

{'__header__': b'MATLAB 5.0 MAT-file, Platform: PCWIN64, Created on: Wed Feb 07 15:26:44 2018', '__version__': '1.0', '__globals__': [], 'A':

Answer 1

如果是matlab.mat文件(似乎是(，请使用：

import scipy.io as sio
array1 = sio.loadmat('adj_data.npy', mat_dtype = True)['A']
