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 {}
