Python3：EOFError: Ra

发布时间：2019-09-28 08:38:33编辑：auto阅读（2604）

    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 {}
