I follow the installations instructions on an Ubuntu 18.04 system until the example it works fine. but then I get.

(py3-cloth) dhananjay@dhananjay-G7-7700:~/Desktop/gym-cloth$ python examples/analytic.py oracle --max_episodes=400 --seed=1336 --tier=1
Yes, cython compiled.

If I create one manually I get a different error:

(py3-cloth) dhananjay@dhananjay-G7-7700:~/Desktop/gym-cloth$ mkdir /home/dhananjay/Desktop/gym-cloth/examples/../render/build

Hi @DhananjayAshok thanks for your interest in the code!
Just wanted to check, for your first post, were you able to install the renderer from these instructions:
https://github.com/DanielTakeshi/gym-cloth#renderer-installation
That should create a build/ directory.
