Can't evaluate accuracy of a calibration

[jessicalfr]

I'm using multical 0.2.2, opencv-python 4.6.0.66, and python 3.10.6 in Ubuntu 22.04.1 LTS.

Does it work by simply making symbol link to alt/alt/ folder?

When I move the images to the alt/alt/folder, I get a different error:

$ multical calibrate --boards charuco_16x22.yaml --image_path alt --calibration calibration.json --fix_intrinsic --fix_camera_poses
INFO - Using boards:
