I've been having the same problem (see Issue #49). In the other issue we noted that we are all using Windows 10/Anaconda setups.

@omeleavitt Guessing you meant to link to issue #48 ? I will investigate the problem on that issue for now and see if there are any clues

Hello,
I think I am having the same problem. Is there any update?

What ended up working for me was making sure there were detections that overlapped between at least enough pairs of cameras such that each was included. To do this, I simply ran the code for calibration in the tutorial for aniposelib (copied into Spyder). Then I edited the list of videos such that it only did two at a time. The subsequent code is looking for a list of frames of the videos where the calibration board is shared between cameras.
