:loader(error): when I run "python -m src.scripts.render_bop_templates test_dataset_name=hope"

[Musa1088]

I installed the code for BOP 2024, then I run the code by python -m src.scripts.render_bop_templates test_dataset_name=hope. However, I got the following error:

:loader(error): Couldn't load file gigaPose_datasets/datasets/hope/models/obj_000026.ply: not found on model path (currently: "/home/musa/Dev/gigapose/src/custom_megapose:/home/musa/anaconda3/envs/gigapose/lib/python3.9/site-packages/panda3d/etc/..:/home/musa/anaconda3/envs/gigapose/lib/python3.9/site-packages/panda3d/etc/../models")

Also, I got this information:

1 1
Known pipe types:
  glxGraphicsPipe
(1 aux display modules not yet loaded.)
3 3
Known pipe types:
  glxGraphicsPipe
(1 aux display modules not yet loaded.)
0 0
Known pipe types:

(1 aux display modules not yet loaded.)

and I dont know what that means. Can you help me about this?

Hi @Musa1088!
Did you get any update on this?
I'm also trying to figure out how this path is set properly.

[mmkolbe]

I managed this setting this variable (in your setup):
export MAIN_DIR=/home/musa/Dev/gigapose/
This variable is listed here (in my setup):
/home/marcel/anaconda3/envs/gigapose/lib/python3.9/site-packages/panda3d/etc/Config.prc.
When looking for the file, the script consider that MAIN_DIR as a base to join to the relative path, like yours gigaPose_datasets/datasets/hope/models/obj_000026.ply

Worked for me and the rendering was done correctly.

Another method is to make sure the paths are absolute.
