pose generating error when using provided silica dataset

when executing "python imgs2poses.py "***/silica", there appears logs below:
Need to run COLMAP
Features extracted
Features matched
Sparse map created
Finished running COLMAP, see /hy-tmp/silica/colmap_output.txt for logs
Post-colmap
Cameras 5
Images # 37
ERROR: the correct camera poses for current points cannot be accessed
Done with imgs2poses

so how can I solve the ERROR?

Start by rerunning python imgs2poses.py against the provided silica dataset and inspect /hy-tmp/silica/colmap_output.txt after COLMAP completes. Trace the post-colmap step that reports that camera poses cannot be accessed; done means the dataset completes without that error and produces usable camera poses.
