Problem with libjpeg

[seb310]

After installing the dependencies I run th neural_style.lua -gpu -1 -print_iter 1 and get the following error:

If the message turns out to be larger than 1073741824 bytes, parsing will be halted for security reasons.

However if I run dpkg -l | grep libjpeg it returns

What could be the problem?

hey!

it sounds like you may be having a problem I had before. I filed it on the torch repo and got some really good help. maybe this thread will help you https://github.com/torch/image/issues/152

This has been fixed in the meanwhile (see torch/image#155). You should re-install the image package.

try: brew install jpeg it worked for me
