[bug] Cannot Compute. "WARNING:root:Nothing to compute" #2902

Description

Describe the bug
After loading images into Meshroom, pressing the Compute button does nothing. The progress bar finishes instantly and the terminal says "WARNING:root:Nothing to compute" (each time the button is pressed).

To Reproduce
Steps to reproduce the behavior:

  1. Open Meshroom either by double-clicking the executable file, running it from the terminal, or running it from terminal using GPU via:

__GLX_VENDOR_LIBRARY_NAME=nvidia __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only "[ my path ]/Meshroom/Meshroom-2025.1.0/Meshroom"

  1. Click New Empty Project.
  2. Save as (name: Monstree).
  3. Drag and drop the folder of Monstree images into the left pane of the high-level interface.
  4. Wait for them to finish loading.
  5. Click the Compute button.

Expected behavior
"Press the “Start” button and wait for the computation to finish. The colored progress bar helps follow the progress of each step in the process."
"As soon as the result of the “Structure-from-Motion” is available, it is automatically loaded by Meshroom. At this point, we can see which cameras have been successfully reconstructed in the “Images” panel (with a green camera icon) and visualize the 3D structure of the scene."

Screenshots

  1. Initially, Meshroom would not run at all. Attempting to run it in the terminal gave:
    qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

I resolved this using the command sudo apt install libxcb-cursor0

  1. Screenshot after starting afresh, running from terminal, New Empty Project, Save as 'Monstree', drag and drop image folder of Monstree images, click Compute three times:

  1. Screenshot after running from terminal using GPU, opening Monstree.mg, and clicking Compute three times:

Desktop (please complete the following and other pertinent information):

  • OS: Linux Mint 21.3 (Virginia)
  • Python version: Python 3.10.12
  • Qt/PySide version: "QMake version 3.1" "Using Qt version 5.15.3 in /usr/lib/x86_64-linux-gnu"
  • Meshroom version: Meshroom-2025.1.0 (from [https://github.com/alicevision/meshroom/releases])
  • Binary version (if applicable): N/A
  • Commit reference (if applicable): N/A

Additional context

  1. I have downloaded Meshroom twice to ensure the files are not corrupt.
  2. The GUI is oddly slow when using 'Save as' or 'Open' and typically requires waiting or clicking in whitespace to open a folder and/or show the files in it. On several occasions, typically when running using the GPU, it has simply frozen. This has made it difficult to generate screenshots, but I have done what I can.
