Question

这应该非常简单：我过去经常使用pickle。这次出了什么问题？

import pickle

with open('data/cifar-10-batches-py/data_batch_1','rb') as f:
    dat = pickle.load(f)

AttributeError: 'function' object has no attribute 'load'

以下内容也失败（如果load被注释掉了）

with open ('data/cifar-10-batches-py/small_batch','wb') as f:
    pickle.dump(images[0:100],f, protocol=pickle.HIGHEST_PROTOCOL)

AttributeError: 'function' object has no attribute 'dump'

所以似乎pickle没有被正确导入？

这是python 2.7.3

Answer 1

pickle被以下内容遮蔽（我未在OP中加入，因为我不知道它是否相关

from cifar import *

它有

# pickle object
# obj: object to pickle
# file_path: file path to store object at in binary cpython blob
def pickle(obj, file_path):
    with open(file_path, "wb") as fo:
        cPickle.dump(obj, fo)

值得怀疑的是，cifar以这种方式创建了一个名为pickle的方法。所以，我需要更加谨慎地做

 from some_library import *

即使导入了pickle，调用pickle也会导致load（）和dump（）上出现AttributeError
