Warning: Can't resume matching without keypoints problem

[fran.garcia]

i like to aling 20 groups of frames but in pairs, i mean, 1-2 after the aligment disable group 1 and enable group 3 and aling, after disable 2 , enable 4 and aling......
The problem is that when i run manually selecting the groups and enableing and disabeling is working but if i run

Code: [Select]

enabled_cameras = []
        for camera in chunk.cameras:
            if camera.enabled:
                enabled_cameras.append(camera)
        chunk.matchPhotos(cameras=enabled_cameras, downscale=1, generic_preselection=True, keypoint_limit=50000, tiepoint_limit=15000)       
        chunk.alignCameras()
the first pair is working but when i disable the 1 and enable the 3 the ouput is
Warning: Can't resume matching without keypoints
Keep key points is enables
version is 1.84 but the same problem in all the versions

What can i do?

Thanks for the help

Adding keep_keypoints=True argument to matchPhotos task should resolve the problem, providing that Tie Point cloud without keypoints doesn't exist at the point, when matchPhotos is called for the first time.
