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 osscores = {} # scores is an empty dict alreadyif 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 {}
