python: pickle.load() raising EOFError
提问by estu
I have a pickle file using .txt format. I want to load this pickle file with python 2.7. The size is 438.5 MB. This is how I load data :
我有一个使用 .txt 格式的泡菜文件。我想用python 2.7加载这个pickle文件。大小为 438.5 MB。这是我加载数据的方式：
def readpickle(path="C:/Python27/Lib/site-packages/xy/"):
with open(path+"filenamereal2.txt","rb") as f:
model = pickle.load(f)
return model
And I get this error
我得到这个错误
itemmodelreal=readpickle(path="C:/Users/Lab Komputasi/Documents/estu/")
Traceback (most recent call last):
File "<ipython-input-33-265e46f74915>", line 1, in <module>
itemmodelreal=readpickle(path="C:/Users/Lab Komputasi/Documents/estu/")
File "<ipython-input-31-fbd3e8b9e043>", line 3, in readpickle
model = pickle.load(f)
File "C:\Users\Lab Komputasi\Anaconda2\lib\pickle.py", line 1384, in load
return Unpickler(file).load()
File "C:\Users\Lab Komputasi\Anaconda2\lib\pickle.py", line 864, in load
dispatch[key](self)
File "C:\Users\Lab Komputasi\Anaconda2\lib\pickle.py", line 886, in load_eof
raise EOFError
EOFError
this is the code that i use to write pickle :
这是我用来编写泡菜的代码：
with open("filenamereal3.txt", "wb") as f:
pickle.dump(result, f)
f.close()
I have used read binary ('rb') to load and write binary ('wb') to write, but it's still have that error. Do you have any idea why it's still error? how can i solve this error?
我已经使用读取二进制（'rb'）来加载和写入二进制（'wb'）来写入，但它仍然有那个错误。你知道为什么它仍然是错误的吗？我该如何解决这个错误？
Thank you for your help....
感谢您的帮助....

I encountered the same error while loading a big file dumped in highest protocol.
我在加载以最高协议转储的大文件时遇到了同样的错误。
This seems to be a bug of the pickle library. I solved it using cPickle instead.
这似乎是pickle库的一个错误。我改用 cPickle 解决了它。
import cPickle as pickle

To load data, wouldn't you want to be reading data ("rb") instead of writing data ("wb")?
要加载数据，您是否不想读取数据（“rb”）而不是写入数据（“wb”）？
Loading data should look like this:
加载数据应如下所示：
with open("C:/Users/Lab Komputasi/Documents/estu/filenamereal1.txt", "rb") as f:
data = pickle.load(f)
Also, using f.close() is unnecessary because you are using a with/as clause.
此外，使用 f.close() 是不必要的，因为您使用的是 with/as 子句。

Make sure your pickle file is not empty, e.g. if you pickle an uninitialized variable.
确保您的pickle 文件不为空，例如，如果您pickle 一个未初始化的变量。
