### 问题：

I´m trying to save and load objects using pickle module.我正在尝试使用pickle模块保存和加载对象。
First I declare my objects:首先我声明我的对象：

>>> class Fruits:pass
...
>>> banana = Fruits()

>>> banana.color = 'yellow'
>>> banana.value = 30


After that I open a file called 'Fruits.obj'(previously I created a new .txt file and I renamed 'Fruits.obj'):之后，我打开一个名为“Fruits.obj”的文件（之前我创建了一个新的 .txt 文件并将其重命名为“Fruits.obj”）：

>>> import pickle
>>> filehandler = open(b"Fruits.obj","wb")
>>> pickle.dump(banana,filehandler)


After do this I close my session and I began a new one and I put the next (trying to access to the object that it supposed to be saved):完成此操作后，我关闭会话并开始一个新会话，然后放置下一个（尝试访问它应该保存的对象）：

file = open("Fruits.obj",'r')


But I have this message:但我有这样的消息：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python31\lib\pickle.py", line 1365, in load
ValueError: read() from the underlying stream did notreturn bytes


I don´t know what to do because I don´t understand this message.我不知道该怎么做，因为我不明白这条消息。 Does anyone know How I can load my object 'banana'?有谁知道我如何加载我的对象“香蕉”？ Thank you!谢谢！

EDIT: As some of you have sugested I put:编辑：正如你们中的一些人所建议的那样，我提出：

>>> import pickle
>>> file = open("Fruits.obj",'rb')


There were no problem, but the next I put was:没有问题，但我提出的下一个问题是：

>>> object_file = pickle.load(file)


And I have error:我有错误：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python31\lib\pickle.py", line 1365, in load
EOFError
