numpy保存和读取dictionary字典

重点：在np.load()后面要加.item()： np.load().item()

import numpy as np
# define
dict = {'a' : [1,2,3], 'b': [4,5,6]}
# save
np.save('dict.npy', dict)
# load
dict_load=np.load('dict.npy', allow_pickle=True)
	
print("dict =", dict_load.item())
print("dict['a'] =", dict_load.item()['a'])

"""
输出：
dict = {'a': [1, 2, 3], 'b': [4, 5, 6]}
dict['a'] = [1, 2, 3]
"""
