core dumped after QGLXContext: Failed to create dummy context #996

I'm using the lastest Phy version from the master repository in Ubuntu 18.04.4 and found the error indicated below. I installed the PyQtWebEngine with pip as suggested. I can reproduce the error in a freshly created conda environment.

It may be related to Issue #979 (I have an NVIDIA GeForce RTX2080 ). In only happens via ssh. 


QGLXContext: Failed to create dummy context
WebEngineContext used before QtWebEngine::initialize() or OpenGL context creation failed.

Running phy via ssh is not currently supported at the moment, unfortunately. However I'm considering ways to make it work in the medium term.

good to know, I also think using Phy via ssh has not the highest priority!

Hi @JoseGuzman and @rossant, I am getting this same error message on my linux machine. I'm not certain on how to get around it. Do you have any updates or more details on how to get Phy2 up and running?

I was able to resolve this issue, however, I 'm not exactly certain what did the trick. I uninstalled, rebooted my machine, and then installed again and everything was fine.
