Issue on rendering Shapenet Dataset

[AmanKishore]

When running:
python render_all.py --save_folder dataset/ --dataset_folder ShapeNetCore.v1/ --blender_root <path-to-blender>

Getting the following error:

ALSA lib confmisc.c:767:(parse_card) cannot find card '0'
ALSA lib conf.c:4732:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

Hi @AmanKishore,

the script would still work with this error (render the images and save cameras). I also have seen the same output before

[AmanKishore]

Cool, I was about to comment that it doesn't seem like an issue and can be ignored!
Thank you for the quick response!

[AmanKishore]

@SteveJunGao Quick follow up, how long is the render_all script supposed to take? And is it dependant on GPU memory?

[SteveJunGao]

It depends on the type of GPU card you're using. Typically, it can run 2-3 days

[AmanKishore]

Whoa that's extensive, any ideas on how to parallelize that across 8 GPUs?

[SteveJunGao]

You can split the whole shapenet objects into 8 different subsets, then use each GPU to render each subset. E.g GPU0 render 0-1000, GPU1 render 1000-2000, etc.

Good suggestion!
