Error in demo

[Yu Hao]

Hi~
I am running the demo, and error happens:

Demo for data/demo/2008_000533.jpg
forward time 0.203548
Traceback (most recent call last):
  File "./tools/demo.py", line 170, in <module>
    superimpose_image.save(superimpose_name, 'JPEG')
  File "/home/haoyu/py2/local/lib/python2.7/site-packages/PIL/Image.py", line 1928, in save
    save_handler(self, fp, filename)
  File "/home/haoyu/py2/local/lib/python2.7/site-packages/PIL/JpegImagePlugin.py", line 607, in _save
    raise IOError("cannot write mode %s as JPEG" % im.mode)
IOError: cannot write mode RGBA as JPEG

I have tried to add .png , remove JPEG, change JPEG into PNG, not working.

Anyone can tell me how to solve it? THX

According this post: python-pillow/Pillow#2724

you can execute:

sudo pip install pillow=4.1.1
