Current Behaviour

Can't dump and raise ValueError:

It seems that CVAT incorrectly merges job annotations because the task has an annotation with frame 10 and 11 in database after creation of annotations in all jobs.

Possible Solution

Steps to Reproduce (for bugs)

1. create task with several jobs:

• 10 images
• 3 overlap size
• 6 segment size

2. create rectangle/polygon/polylines/points (track) annotations in jobs
3. dump CVAT for images 1.1 annotations
   (GET query /api/v1/tasks/1/annotations&format=CVAT for video 1.1)

Context

Your Environment

• Git hash commit (git log -1):
• Docker version docker version (e.g. Docker 17.0.05):
• Are you using Docker Swarm or Kubernetes?
• Operating System and version (e.g. Linux, Windows, MacOS):
• Code example or link to GitHub repo or gist to reproduce problem:
• Other diagnostic information / logs:
  Logs from `cvat` container
