Unable to make env on server without display. about sapien HOT 5 CLOSED

Sorry for my mistake, I rechecked after your comment, image was fxiangucsd/sapien-rl-env and not fxiangucsd/sapien-build-env.

But yes fxiangucsd/sapien-rl-env this image works fine, only thing required is just to install sapien using pip install sapien.

from sapien.

Here are the minimal steps I found to enable offscreen rendering.

First, make sure at least graphics,utility,compute are added to NVIDIA_DRIVER_CAPABILITIES when building the Docker.

ENV NVIDIA_DRIVER_CAPABILITIES graphics,utility,compute,display

Next, install the libglvnd-dev package. (in fact, libegl1 + libxext6 should also work)

Next, you need to make sure both /usr/share/vulkan/icd.d/nvidia_icd.json and /usr/share/glvnd/egl_vendor.d/10_nvidia.json exist. If not, copy it from the corresponding location on the host machine into the Docker. These files should be provided by the driver, but many servers seem to miss them somehow.

Let me know if this works for you.

Thanks for the reply, I will try the solution and update.

Also I tried to use fxiangucsd/sapien-build-env image to create a docker container and when I installed sapien in it using pip it worked. I got output.png when running offline example.

So I guess issue is with adding graphics to NVIDIA_DRIVER_CAPABILITIES. I will check the above things and then revert back.

Also please add these instructions somewhere in the readme or documentation.

I am quite surprised that sapien-build-env docker works, as it is not designed to run SAPIEN but for compiling only.

I just figured out the capability thing yesterday, and it is now in the readme on the dev branch. I'll also provide the ICD files with SAPIEN in the next release (as a temporary hack for people with a partial driver installation).

Thx, this works for me. I did not use docker.
I used sudo find / -name nvidia_icd.json to locate and copy the file and used export to append the nvidia environment variables.
