Fix ZeroDivisionError during calibration - #1819

Sorry to bother you again.Just to make sure. I saw 9 failed checks on this page. Does it mean the bug [1818] has not been totally fixed?Many thanks.

Hey @BinZJU, no worries, it's just that the patch got merged before I had the chance to fix the unit tests (which I did shortly after with cd97518). It doesn't affect your experience though, it is only some automatic tests that are run on our side :)

Thank you. Also, thanks for the help from MMathisLab.
Actually, I followed these steps. But I still can't get the video analyzed as expected.

1. Open the Anaconda Prompt (Admin)
2. conda activate DEEPLABCUT
3. pip install git+https://github.com/DeepLabCut/DeepLabCut.git@fix_1818 (OR pip install git+https://github.com/DeepLabCut/DeepLabCut.git, I've tried both)
4. python -m deeplabcut
5. Load the existing project
6. Analyze videos (checked Calibrate animal assembly and Assemble using animal identity )
7. ZeroDivisionError is present……

Do I need to totally remove DeepLabCut and then reinstall it?
I apologize for any inconvenience and thank you for your time.

Hey, Jeylau @jeylau !Another question, after reinstalling the DCL with pip install git+https://github.com/DeepLabCut/DeepLabCut.git@fix_1818, can I still use DLC with GUI? In other words, do I have to use DLC without GUI in order to get the ZeroDivisionError bug fixed?
Thank you so much!

Hey @BinZJU, the version you installed is DLC 2.2.1 + the small extra fix. So you can use it normally, either with or without GUI 😊

Thanks! DLC really helps! And it finally works. Just to let you know, I created a new conda env with Python=3.7 to install the DLC2.2.1+1818 fix, then everything goes well. I don't know what's wrong with the previous env. The only difference is that it is based on python 3.8.
