Error when exporting training set

[vigji]

I am trying to export a training dataset from some annotated movies. I am working on a macOS and installed the Annotation Tool available on the website. Running stuff on a mac solved the issues described #1, even though those are still standing on the Windows machine.

I have annotated a bunch of frames and I wanted to generate a training dataset from them. I am working with 3 cameras, I annotated from 1 camera all key points, and from the other 2 I suppressed one in each as it was not visible.

This is the window I have just before the export:

If I export, the tool crashes and I get the following report:

Any way you can help me?

Hi,

The root cause of your issue seems to be that MacOS doesn't like it when popup windows are created by a thread other than the main thread. The only time that happens is when I try to export a trainingset without having the calibration files added to the dataset.

This is definitely a bug that needs fixing, but I think you can get around it by making sure that you add your calibration files to the dataset. The easiest way of doing this is by clicking the big blue "plus" button in the annotation mode. This should do two things:

1. You should be able to see the reprojection error statistics instead of the blue "plus"
2. There should now be a folder called CalibrationParameters inside your dataset directory, containing all your calibration '.yaml' files

I hope this helps! Please let me know if missing calibration files are not the cause of the issue.

That was it, worked like a charm! Thank you very much for your help, I'll keep reporting on this! :) Feel free to close the issue if you want, or keep it up for the popup window bugfix.

Thanks again!
