Preprocessing error

[Yi-Shi94]

Preprocess part gives me quite a headache. I have the following error:

terminate called after throwing an instance of 'std::runtime_error'
what(): Pangolin X11: Unable to retrieve framebuffer options
DeepSdf - INFO - ShapeNetCore.v2/04256520/45d3384ab8d5b6295637fc0f4b98e88b/models/model_normalized.obj --> data/SdfSamples/ShapeNetV2/04256520/45d3384ab8d5b6295637fc0f4b98e88b.npz

I run this on a remote GPU server. Previously, I resolved X11 can't open display X by enabling X11 forwarding on client-side. Now it gives me this kind of message and still generates 0 output. I have no idea how to fix this.

• Ubuntu 16.04.5 LTS
• Pangolin cloned and built with the master branch.

I have the same error.
This program doesn't generate ".npz" data

Does anyone have any solutions?

[Yi-Shi94]

For running it on a remote server, no.

I think if you run it under a local machine, It may work.

I run it under the local machine, but it still doesn't work. Do you have solutions?

This error occurs when the platform does not have proper support for the GLX extension. As I mentioned in the comments on issue #35 I wouldn't necessarily expect certain setups such as remote VMs to be capable of running the OpenGL components of the preprocessing code. @WordBearerYI , have you tried running in headless mode by setting the environment variable mentioned in the README?

I was able to generate .npz files even on remote server
use
export PANGOLIN_WINDOW_URI=headless://
Also, make sure the remote server has graphics nvidia drivers running.

This indeed solved the X display problem but leads to new problem #95
GLSL Program link failed: No details provided.
I am running on a remote server.
