"QXcbConnection: Could not connect to display"

[calufa]

Hi, thanks for the code.

I am having trouble running the code. I successfully compilee the project, but when I try to run ./face_swap_image --cfg test.cfg, I get the following error:

QXcbConnection: Could not connect to display
Aborted

I am running the code inside a docker container.

The face swap applications require an OpenGL context to work.
This is done using Qt offscreen rendering.

I have no way to test the application in the same environment you do but try to follow this post I think it might help: http://stackoverflow.com/questions/25281992/alternatives-to-ssh-x11-forwarding-for-docker-containers/25334301#25334301

Great! :)

I ran it on docker too, met the same problem. Finally solved it by switching to a docker image with desktop.
Now i successed:

It's really cool ! From face detection、face segment、3D models to face swap, that's amazing works ！

These are results on my docker container :
Under these cases , it performs well :

But the below groups seem abnormal:
Group 1:



Group 2:



Group 3 (profile):



Group 4(size between face and nose、eyes、mouth):

1、Noticing this https://github.com/YuvalNirkin/face_swap/issues/3 , i don't know whether it could be caused by my no GPU environment and those're just errors occur. So could you please run these pictures on your machine to cheak it？

[YuvalNirkin]

Congratulation! You got it working!
The issue is related to the algorithm as I do get about the same results:

This is a problem with the 3DMM fitting as you can see in the left debug image. It has issues with very high resolutions. Resizing the images can sometimes help:

Hi @YuvalNirkin
I am running this project on an AWS instance. And getting

QXcbConnection: Could not connect to display 
Aborted (core dumped)

Any luck running it on cloud ?

Thanks

Hi @akashgoyal
I haven't tried running the project on a AWS instance but you can try one of the following solutions:

Please confirm if any of those work for you.

Hi @YuvalNirkin
I was trying https://comtechies.com/how-to-set-up-gui-on-amazon-ec2-ubuntu-server.html
And I am not able to proceed after step 2.

Is their a way to do this completely command line. Can you suggest on possible code changes ?

[YuvalNirkin]

You can replace the OpenGL renderer with a software renderer.

I sovlve the QxcbConnection Could not connect to display by install XManager and "export Display=:localhost:11.0” in ~/.bashrc

But After that I come across the following question.

QXcbConnection: Failed to initialize XRandr
Could not initialize GLX
