Walkthrough

The changes in this pull request involve the addition of a new import statement and a method call in the cvat/apps/engine/task.py file. Specifically, TaskFrameProvider is imported to enable the generation of a preview image after the task creation process. This new feature is integrated into the _create_thread function, where the preview image is prepared and saved in the cache. The overall structure and logic of existing functions remain unchanged.

cvat/apps/engine/task.py	Added import for TaskFrameProvider and a method call to generate a preview image in _create_thread.

Poem

In the burrow deep, where tasks do thrive,
A preview now hops, keeping dreams alive.
With a flick of a tail and a dash of delight,
Images dance in the cache, oh what a sight!
TaskFrameProvider, our new friend so spry,
Brings forth the vision, as tasks soar high! 🐇✨

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
