Description
I have installed all the dependencies and am able to import opensfm successfully. However, when I try to run the berlin example as given in the documentation, I get a segmentation fault as follows:
2022-03-17 14:45:18,541 INFO: Starting incremental reconstruction

Segmentation fault
Any help in this? I am using centOS.
Thank you

Research direction
Start by reproducing the Berlin example on CentOS using the documented command and capture the complete environment and dependency details. Inspect the incremental reconstruction stage immediately before the segmentation fault, using the logged two-view reconstruction and Ceres output to narrow the failure. Done means identifying a reproducible cause and confirming that the example completes without a segmentation fault.
