EOFError: Ran out of input

使用pickle.load(f)加载pickle文件时，报错：EOFError: Ran out of input. 
可能原因：文件为空。 
解决办法：加载非空文件。 
其他解决办法： 

1、加载前判断文件是否为空

import os
scores = {} # scores is an empty dict already if os.path.getsize(target) > 0: with open(target, "rb") as f: unpickler = pickle.Unpickler(f) # if file is not empty scores will be equal # to the value unpickled scores = unpickler.load()

2、捕获异常

open(target, 'a').close() scores = {}; try: with open(target, "rb") as file: unpickler = pickle.Unpickler(file); scores = unpickler.load(); if not isinstance(scores, dict): scores = {}; except EOFError: return {}
