Python：IOError: image file is truncated 的解决办法

代码如下：

#coding:utf-8
from PIL import Image
import pytesseract
def test():
im = Image.open(r"pic.gif")
vcode = pytesseract.image_to_string(im)
print vcode

执行以上代码进行简单验证码识别的时候会抛出一个异常：

Traceback (most recent call last):
File "D:\test\vcode.py", line 15, in <module>
main()
File "D:\test\vcode.py", line 9, in main
test()
File "D:\test\test.py", line 8, in test
vcode = pytesseract.image_to_string(im)
File "build\bdist.win32\egg\pytesseract\pytesseract.py", line 143, in image_to_string
File "D:\Program Files (x86)\Python\Python27\lib\site-packages\PIL\Image.py", line 1749, in split
self.load()
File "D:\Program Files (x86)\Python\Python27\lib\site-packages\PIL\ImageFile.py", line 232, in load
"(%d bytes not processed)" % len(b))
IOError: image file is truncated (5 bytes not processed)

解决办法是，再添加如下2句代码：

from PIL import ImageFile
ImageFile.LOAD_TRUNCATED_IMAGES = True

最终，完整的代码如下：

#coding:utf-8
from PIL import Image
import pytesseract
from PIL import ImageFile
ImageFile.LOAD_TRUNCATED_IMAGES = True
def test():
im = Image.open(r"pic.gif")
vcode = pytesseract.image_to_string(im)
print vcode
