Dict的加载：

import json

def load_dict(filename):
 '''load dict from json file'''
 with open(filename,"r") as json_file:
  dic = json.load(json_file)
 return dic

Dict的保存：

import json
import datetime
import numpy as np

class JsonEncoder(json.JSONEncoder):

 def default(self, obj):
  if isinstance(obj, np.integer):
   return int(obj)
  elif isinstance(obj, np.floating):
   return float(obj)
  elif isinstance(obj, np.ndarray):
   return obj.tolist()
  elif isinstance(obj, datetime):         
   return obj.__str__()
  else:
   return super(MyEncoder, self).default(obj)

def save_dict(filename, dic):
 '''save dict into json file'''
 with open(filename,'w') as json_file:
  json.dump(dic, json_file, ensure_ascii=False, cls=JsonEncoder)
