installation errors (SIGSEGV, openGL)

[baedan]

i ran into segfault and missing openGL dependency (might be macOS specific) errors after installation. figured out how to get around them -- hope this could help someone else.

for SIGSEGV:

1. edit your setup.py, change the matplotlib line to 'matplotlib==3.3.3',;
2. reinstall with pip install -e ..

for openGL:

1. install a newer version of pyglet with pip install pyglet==1.5.11. pip will complain, but the install should go through.

I had to do this the following in addition to what you suggested:

export LD_PRELOAD=/usr/lib/libstdc++.so.6 

Also for mujoco, it's open source now so just install it off github.:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/user/.mujoco/mujoco210/bin
