Can't visualization with vis_snapshot.py

[bruinxiong]

Thanks to this fabulous work. However, when l use vis_snapshot.py to visualize smpl parameters of People-Snapshot, I get the following error:
/app/tools$ python vis_snapshot.py
INFO - 2021-06-22 15:08:19,340 - acceleratesupport - OpenGL_accelerate module loaded

How to solve it ? I find some solutions via google, but all don't work.
Thanks!

I run this code in docker container.

This visualization code requires the computer to have a display.

@pengsida Thank you for your reply. Of course, I connect a display. I have solved the visulization issues caused by PyOpenGL, pyglet and freeglut3. By the way, I found that if I use Dockerfile to build docker image, after run the container, maybe the unknown device type error from spconv library will be reported. This issue may relate to the version of spconv, CUDA, Pytorch and even python. So, if some guys meet this issue like me. Please refer those links ( traveller59/spconv#58, traveller59/spconv#152) to solve. In other words, change to lower version of spconv, such as v.1.0 not v.1.2.1 in spconv.sh and modify the Dockerfile to build the available image with corresponding version of cuda, cudnn and pytorch.

Furthermore, if some guys meet the error like me for vis_snapshot.py and render_mesh.py as following:
libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast
you may refer to this link (jessfraz/dockerfiles#253), maybe it will help you to solve the issue.

Hi @bruinxiong , how do you solve the no display issue?
