IOError: broken data stream when reading image file

Question

This is the code(a simple python code which could add a number to a picture):

from PIL import Image, ImageDraw, ImageFont

def addnum(number, filepath):
    img = Image.open(filepath)

    width, height = img.size

    draw = ImageDraw.Draw(img)

    front_size = height/4
    ttf_front = ImageFont.truetype('Arial.ttf', front_size)
    draw.text((width - front_size, 0), number, (255, 0, 0), font = ttf_front)

    del draw
    img.save('wechat_addnum.jpg')
    img.show()

if __name__ == '__main__':
    addnum('4','wechat.jpg')



Traceback (most recent call last):
File "<stdin>", line 1, in <module>

IOError: broken data stream when reading image file

I don't know the real problem, and from the google and other questions from stackoverflow I cannot find the method which could solve this problem. Thank you!!

This is a know issue. Try to update Pillow using pip install Pillow --upgrade
