Python3:EOFError: Ra

发布时间:2019-09-28 08:38:33编辑:auto阅读(1972)

    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 {}
