Osmesa for mujoco installation

[Viraj Mehta]

Hi Predrag,

Thanks for the response, and sorry for not being more clear. I `find` it in /usr/include/GL on GPU3 but not on GPU20 in /usr/local, /usr/include, and also just /usr/. So that leads me to believe that it’s not around. Definitely could spend more time looking but was asking you to spare crawling the entire machine, since /usr seems like where it should be. 

I also read Anthony's email yesterday, though I think my situation is different in that the folks at OpenAI have obfuscated the compilation to the point that I only can see what is going on by trying to instantiate a gym environment or really digging into their library code.

I’m happy to keep looking around using the unix tools or Python or whatever but it does seem missing to me. I’d appreciate some guidance.

Thanks,
Viraj

I was able to get a license for the machine and to download the appropriate software from their website and the mujoco-py repository. However, when I actually try to run the  Mujoco gym environments, I am running into gcc compilation errors around a missing copy of osmesa.h. Do you know whether we have that installed or if it would be possible to do so?
