segmentation_fault

[cduguet]

Hi!

By trying to run both easy_pbr and permuto_sdf I encounter the problem Segmentation fault (core dumped).

• I have tried on multiple aws ec2 instances, running ubuntu 20.04 or ubuntu 22.04. I've run it inside the docker containers running on top of nvcr.io/nvidia/pytorch:22.08-py3 (and also the experimental version), as well as installed it natively on the ec2 instance.
• I've tried with vnc on gdm as a remote desktop access as well as on NICE DCV.

When I'm trying to run permuto:

python permuto_sdf_py/train_permuto_sdf.py --dataset dtu \
> --scene dtu_scan24 \
> --comp_name comp_3 \
> --exp_info default
args.with_mask False
args.low_res False
checkpoint_path /workspace/permuto_sdf/checkpoints
with_viewer True
has_apex True

When I'm trying to run examples/pbr.py I get:

Segmentation fault (core dumped)

How can I solve this? I'm out of options.

Hi @cduguet,

In general easypbr is not meant to run on a headless machine. To disable it, you can run the training script with the "--no_viewer" flag.
Please let me know if that solves the issue for you.

Hello,
I have already tried running with --no_viewer in the past, but my results so far are just gibberish, so I wanted to use the viewer to debug camera positions and maybe other factors.
In what platforms/OS is the software tested to work?
