IOError: could not read bytes

According your introduction , I execute it in shell, here I met a problem:

Hmm, is something wrong with your SciPy installation?

[anishathalye]

Also, did you download the right VGG net (the one linked in the repo)?

[dgutyanghs]

I did use the link to download vgg file in your repo。

Pre-trained VGG network (MD5 8ee3263992981a1d26e73b3ca028a123) - put it in the top level of this repository, or specify its location using the --network option.

But, I got a wrong MD5 value below:

alex@alex-ubuntu1604:~/myprivate/github/neural-style$ md5sum imagenet-vgg-verydeep-19.mat 
8029d2d6941afbe121eb4c0a3e185e1f  imagenet-vgg-verydeep-19.mat

[anishathalye]

That means the file is corrupted - you should redownload it.

[dgutyanghs]

Yes， it works！
