Maybe your machine ran out of memory? Can you enable verbose with verbose=True?

[rishabhramteke]

Thank you for your response. I will try debugging. Do you think there is any memory leakage in the trangulation code?

[sarlinpe]

triangulation.main(..., verbose=True). No afaik there is no memory leak.

Traceback (most recent call last): File "pipe_test.py", line 75, in triangulation.main( TypeError: main() got an unexpected keyword argument 'verbose'

I checked by using dmesg -T and got this output : Out of memory: Killed process 86403 (colmap) total-vm:18077248kB, anon-rss:15917864kB, file-rss:2812kB, shmem-rss:0kB, UID:1000 pgtables:31392kB oom_score_adj:0

Do you think increasing my RAM would help? Or is there some other issue (maybe in the features extracted or matches)

[rishabhramteke]

The code gets stuck during bundle adjustment. Maybe the issue is with that. Should I make the check = False in "Hierarchical-Localization/hloc/triangulation.py", line 138, in run_triangulation subprocess.run(cmd, check=True)"?
