Depth Map Estimation fails after applying SFMTransform about alicevision

[belveder79]

seems to be linked to the graphics card type GTX980 - it works on single RTX3060 but also fails on multi-GPU setup with 4 NVIDIA TITAN V cards...

[belveder79]

ok, now I have tested it on four setups using MeshRoom 2023.2.0...

1x 4-TITAN-V - failed
1x 4-GTX980 - failed
1x 1-GTS1060 - worked
1x 1-GTX3060 - worked

seems to be a multi-GPU issue?

I have the same issue, but it is working when rolled back to Meshroom 2023.1.0. Tested on g4dn.12xlarge

I encountered this same error using the current (Sept 2, 2023) precompiled Linux binary, with all default settings on my own photo dataset.

My system uses one RTX 2080 Super for graphics output, and 4x Tesla P100's for compute. OS: Ubuntu 22.04

I believe I can support the Multi-GPU hypothesis. If I use the system variables to hide all but one GPU from Meshroom, the computation of Depth Maps goes ahead without error.

user@computer:~$ export CUDA_VISIBLE_DEVICES="1"
user@computer:~$ ./Meshroom

Note: the CUDA_VISIBLE_DEVICES variable takes either a GPU ID number, or a comma-separated list of GPU ID Numbers. So if your desired GPU is ID: 0, then you'd put ="0" or if you're trying multi-gpu, it should be something more like ="0,1,3," etc.
