Calibration error, replication instability

[medaigle]

When I run the example data from the tutorial multiple times, I get extremely varied results in the pixel reprojection error -- from 1 to 10000. I ran the calibration 6 times (restarting the kernel in between each) and only got a good result 1 time; I got an error of 125, then 1.8, then 20084, then 1064...

I created a fresh installation of aniposelib inside its own conda environment, hoping to fix this problem but that didn't help.

I did not have this issue when I first tried using aniposelib back in May, although I wasn't intentionally trying to replicate results at that point. The only thing that has changed since then is some Windows updates; could that cause this problem? I'm running Windows 10 1909 18363.959

Is anyone else having this problem?

Looks like the calibration is not deterministic, so maybe it could be solved first.
