### Install `mujoco-py` with headless gpu rendering
You may perform additional steps to build `mujoco-py` with gpu rendering support on a remote server without any monitor attached.

First, check whether mujoco_py has already been built with headless gpu rendering
```
$ python3
import mujoco_py
print('gpu' in str(mujoco_py.cymj).split('/')[-1])
```
If the output is `False`, you may perform the steps below to build gpu extension

```
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia-000
$ sudo mkdir -p /usr/lib/nvidia-000
$ python3
import mujoco_py
print('gpu' in str(mujoco_py.cymj).split('/')[-1])
# True
```



See the [full documentation](https://openai.github.io/mujoco-py/build/html/index.html) for advanced usage.
