Segmentation fault about vrn

[AaronJackson]

Please use CUDA 7.

[AaronJackson]

Sorry, I meant to say CUDA 7.5 or 8.0

[yar-resh]

Thank you for your advise and sorry for my late response.

As you said, I've tried to install CUDA 7.5, and later CUDA 8.0
Also I've switched from Ubuntu 16.04 to Ubuntu 14.04
I could not use CUDA 7.5 because (if I understood it correctly) my video card is too recent.
But with CUDA 8.0 I have the same error - segmentation fault.

Do you have any idea how else it can be fixed?
Thank you.

[AaronJackson]

It definitely does not work with CUDA 9 so that's the first part ruled out. If you open Adrian's face-alignment main.th in a text editor, and in a terminal open the th interpreter, you run line by line to see what fails. That will help us figure out where the problem lies.

Hi @AaronJackson !

Would this project work without cuda gpu? I'm trying to run it with "device" set to "cpu" and I'm also getting the same output as @yar-resh.

Thank you!

[AaronJackson]

Hi @GregaVrbancic. Same result but for different reasons. While the VRN code will run on the CPU, the face-alignment will not, unfortunately, as it is used nngraph to build the model and converting it to float doesn't seem to work).

Hi, @AaronJackson
Could you indicate the suitable GPU ram size?

Is this caused by ram size?
Thx.

[AaronJackson]

@yzhang559 Yes. What GPU do you have? You can check with nvidia-smi

[yzhang559]

@AaronJackson
It's NVIDIA GeForce GTX 645, only 972MB

[AaronJackson]

@yzhang559 Yes that is not enough.

Do you have any idea how to resolve this problem?
I have centos7

[AaronJackson]

Open a torch shell and run through the code from face alignment, line by line. The issue is probably from one of the requires.

Hello @AaronJackson, thanks for the support. Also, how much memory is needed?

Also, I'm getting a similar error as @yar-resh. When I go through the requirements in main.lua line-by-line in th, I get a Segmentation fault (core dumped) for the line local utils = require 'utils'. So, moving to utils.lua, I get a Segmentation fault (core dumped) when I try to run the py.exec lines that imports the Python libraries. So, I tried importing each library individually, and it seems that the matplotlib libraries cause the segmentation fault. Therefore, I chose to only import the numpy library, and th utils.lua runs fine. So I proceed to run run.sh with these lines commented, and I get the following error:

@longu How did you end up with an input of 1x68x2

[leon-nn]

@AaronJackson I'm not sure, but I found that I had some .t7 files in the examples folder from playing around with the opts parameters (I had changed the outputFormat from txt to t7), and having those files in the input folder caused that error. I deleted them and it runs fine now -- with the code I can produce and visualize the .raw files. However, I still get a segmentation fault message from the line in run.sh that calls vis.py when displaying some of the .raw files, despite being able to view all of them. It seems like for me there are certain issues in calling visualization libraries from Python (matplotlib and visvis): in the case of importing matplotlib in utils.lua, it causes the code to fail as previously described.

[yzhang559]

@longu Maybe you can try to include 'do' and 'end at the beginning and end of the utils.lua, like this:

[JimmyLauren]

Hi @AaronJackson , I ran your code and it showed up like this, what should i do to get a 3D model?

[AaronJackson]

Note to everyone: If your issue does not have anything to do with a segmentation fault, please open a separate support ticket. This is getting impossible to keep track of. I will close this ticket now, but we can continue discussing.

@JimmyLauren haha, oh dear. Did you change any of the lighting code? It is being displayed but it seems like the lighting code has been messed with, or you have some issues with opengl. If you haven't changed the lighting code in render.m please try starting matlab with matlab -softwareopengl -desktop

@yar-resh @AaronJackson I have the same problem
