OSError: [Errno 24] Too many open files

[Aur1anna]

Hi，thanks for your amazing work!!

When I use run.py to obtain novel views, I have this error: OSError: [Errno 24] Too many open files.

The command all I used:

python lib/colmap/imgs2poses.py -s examples/stone_rgb
python run.py --type evaluate --cfg_file configs/mvsgs/colmap_eval.yaml test_dataset.data_root examples/stone_rgb save_video True

and more details:

Thanks for your contribution again!! And any help will be appreciated!!

Thanks for your kind word! Actually, I haven't encountered this error yet. Do you also get the error when running the data in the example we provided? Maybe you can try setting num_workers to 0, change that here.

Hi, thank you for your reply! yeah I also get this error when running the example/scene1.

After "ulimit -a" I found the "open files (-n)" equals 1024 and I try to fix this by using "ulimit -n 2048". Now it seems good, 60 pictures and video can be saved, but the whole output video is just a black screen. And this happened on both example/scene1 and my stone_rgb dataset.

Maybe all of this is due to an environment issue? But I don't remember any errors during the environment setup process. Anyway I'll try again later.

I set up a new env and it just didnt work again. Maybe 60 pictures is considered enough for me :) :) :)

Thank you for sharing! If you want, you can turn 60 images into a video through post-processing.
