I'm running into an issue with cvat-sdk.

client.tasks.retrieve(83)

This call throws a 403 for maintainers in the org if they're not the owner of the task. But if I log into the UI with the same (non-admin, non-owner) user, I can view all tasks, export annotations, etc.

It's definitely possible that I am doing something wrong, but it makes me think there's an issue with the SDK (since everything works fine in the UI).

Hi, not sure if anyone can help me here.

I'm having an issue with setting up kibana on my EC2 instance (CVAT being set up over https using custon SSL certs). Locally, I am able to run kibana no problem and it functions properly. However on my EC2 instance I'm getting a server error 500 (Failed to load resource: the server responded with a status of 500 ()) every time I try to access https://\<HOSTNAME>/analytics/app/kibana. Only kibana is affected here, the rest of CVAT functions properly.

Looking through the docker logs it seems that elasticsearch, logstash and kibana are all up and running. In the cvat_server logs this error occurs every time I attempt to access kibana:

ERROR:django.request:Internal Server Error: /analytics/app/kibana

I've been searching quite intensely for a solution but havn't found a fix so far. Anyone have an idea of what may be wrong?

anyone know of a way to use cvat_sdk to import project backups into an org? I can't find a way to do this, and if possible would like to avoid use of raw API requests to keep things simple.

This method exists: projects.create_from_backup() but it doesn't seem to support setting the org of the project.

Is there a way I can set the org during the create_from_backup call, or set the org of the project afterwards using the cvat_sdk python module? Thanks for your help!

We are happy to present a new video of our CVAT Course.
This video demonstrates how to use the API in CVAT. The process includes three easy steps:

First, you'll learn how to send out authentication requests.

Next, you'll be creating a task and monitoring its status.

And finally, you'll see how to export datasets.

CVAT uses a pull-based interaction model where you initiate the communication by sending HTTP requests.

When dealing with z-order in cvat is there any way just to move a label up one or down one. When I try to move foreground/background it always moved it to the top or bottom of the order. Also is there any ways to delete layers created when moving labels to foreground/background?

I'm trying to understand how to verify a webhook signature.
The documentation here: https://github.com/opencv/cvat/blob/develop/site/content/en/docs/administration/advanced/webhooks.md
Gives an example for an empty request body, which I can duplicate in python with: hmac.new(key=b'mykey', msg=b'', digestmod=hashlib.sha256).hexdigest()
I'm using requests in my endpoint to receive the webhook call. I've tried to replace my msg with request.get_data() and request.json as well as various keys in the request.json all without success. Any idea what the right message should be?

We are happy to introduce the 4th and 5th videos in our product tour, which will guide you through annotating in the interpolation mode.

Interpolation and Annotation with polygons

The process of interpolation is straightforward, consisting of three simple steps:

  • Establish the frame step.
  • Select a shape and label.
  • Annotate frames in accordance with the established frame step.

CVAT will then handle the rest, resulting in up to a 10-fold increase in the speed of the annotation process.

In addition to the video on annotation using the interpolation mode, we are introducing another video that further demonstrates the practical application of this technique.

In our 5th product tour video, we will take you through a step-by-step guide on how to effectively annotate using polygons. The process is simple and easy to follow, consisting of four basic steps:

  • Selection of the appropriate tool and label.
  • Annotation: adding and removing points, adjusting polygons, and more.
  • Tips and tricks for annotating with polygons in interpolation mode.
  • Reviewing and verifying the results.

All concepts are explained through practical examples for better understanding.

Streamline annotation with CVAT by integrating Hugging Face and Roboflow models

CVAT already has impressive automatic annotation abilities with its built-in models. Today, we announce that we further advanced them by adding third-party DL models from Hugging Face and Roboflow. This integration has the potential to increase annotation speed by an order of magnitude, depending on the model. In this article, we show how these models can improve your annotation process.

CVAT Course. Lecture #6: Using SDK

We are glad to announce the release of the 6th video in the Computer Video Annotation Course, which focuses on the CVAT SDK. This video provides a comprehensive guide to using the SDK, covering the following topics:

  • The need for using SDK.
  • Getting started with installation, APIs, features, and utilities.
  • Real-life examples of use.

We believe this video will be an invaluable resource for anyone interested in data annotation and computer vision. To further reinforce your learning, we have included a brief homework assignment that utilizes the SDK. We encourage you to check it out and let us know what you think.
