failed run in matlab, in main.lua line8: local utils = require 'utils'

Hi, @AaronJackson , Thanks for your meaningful work. When I run your demo, I encountered an error as follows. I try to solve this problem according to Unsupported HDF5 version and Error while running "th eval.lua but I failed.

You are looking at the wrong part of the error. The useful part suggests that you do not have an X server running. Are you connecting over SSH? if so, try using SSH with the -X flag.

[JackieLeeTHU11]

@AaronJackson yes, I connect the server over ssh by a jump server. I think -X flag is not useful. are there any other solutions?

[AaronJackson]

The code is trying to display a window but can't because there is no window. You have several options:

• Use X Forwarding (-X ssh option) and make sure you have an X server running locally, such as Xming on Windows, X11 on MacOS, or just a normal desktop on Linux.
• Generate a virtual framebuffer with something like xvfb, but then you still can't see the results without X forwarding
• Comment out X related stuff from Adrian's face alignment code, and adapt the run.sh to generate the obj files instead of displaying them. This can be done using the provided raw2obj.py script.
