When I start training my DNN model, I get the following error:

==> doing epoch on training data:

I am not able to find a solution to this. Is this a graphicsmagick problem? I installed graphicsmagick by 'luarocks install graphicsmagick' . I even tested by opening torch in terminal and tested whether luarocks was installed or not and it gave positive result. Do I also need to install graphicsmagick by sudo apt-get install graphicsmagick?

Please help.

Now I have even installed graphicsmagick, and stll I am getting the same error. So what could possibly cause the error?

Thanks in advance

See if /home/OPENFACE_FINAL/openface/aligned/054/54-11.png is corrupted or its source.

Actually the problem was with the files only. Thanks Bill, I had figured it out earlier myself but couldn't post here. I am working on a remote server, and the files were not copied correctly on the remote server. That's why the problem was there.

Thanks and sorry for the inconvenience.
