Exporting Datumaro Project - no occluded and z_order shape attributes in the output

I have annotated a video using interpolation mode in CVAT. I then exported the task as a datumaro dataset. I tried to output annotated frames using the following command:

datum project export -e "/item/annotation" --filter-mode "i+a" -f yolo

But I am having the following error:

I tried to figure out the problem with no results.

I am working on windows 7. I installed datamaru as following:

pip install 'git+https://github.com/opencv/cvat#egg=datumaro&subdirectory=datumaro'

• Ensure you have the corresponding file in <project_dir>/.datumaro/extractors or <project_dir>/.datumaro/plugins (depending on the CVAT version, the latter is for actual). If there is no such file for some reason, you can find it here.
• Ensure you have <project_dir> in your PYTHONPATH env. variable
• Install cvat/util/cli/requirements.txt if you haven’t done this

If you haven’t found config.yml in .datumaro, I believe you exported the task from an outdated version of CVAT, and installed the actual version from develop, where project layout has been changed a bit. The corresponding to CVAT version of Datumaro is available at <project_dir>. It is installed as described in the readme there.

Regarding requests package - it should have been installed from <project_dir>/cvat/utils/cli/requirements.txt. This step is described in the README. The cvat package required should be taken from the <project_dir> by providing PYTHONPATH=<project_dir>, which is also mentioned in the readme.

I’ve just rechecked if these steps work (on Ubuntu, though) - they did. However, I’ve found that some attributes were not being passed this way, specifically occluded and z_order. This can be fixed by this patch (#1271). Meanwhile, exporting as CVAT xml and importing CVAT project in Datumaro should work without an issue.
