Questions about rigid obstacles in "Learning to Simulate Complex Physics with Graph Networks"

Hi, I read the paper many times and was pretty sure that I have followed most of the details of the paper while re-implementing the network. The differences between mine...

Speeding up, GPU and 3D

@JaroslavVitku Hi, were you able to solve this problem? I encountered this issue as well. Thanks!

Unknown reason for failure to get solutions

@capaulson Actually I didn't have mpmath. The mpmath was already removed when I tried to setup OpenRave for regenerating the .cpp code. mpmath did cause problem in that step as...

Unknown reason for failure to get solutions

> Hi @kracon7 , did you solve this issue, I had the same issue that ikfast was failed to get ik solution. No, I wasn't able to solve it.

Failed to initialize OpenGL

Is there a solution to this (can't use env.render and env.sim.render in the same environment) yet? I'm experiencing the same issue. And my current work around is to set and...
