Walkthrough

The changes involve refactoring how video files and configurations are managed across various modules. Key modifications include transitioning from list-based to dictionary-based video reader management, enhancing error handling for dataset retrieval, and shifting to batch processing for model evaluations. Additionally, input data normalization and improved logging practices were introduced to enhance clarity and robustness in handling datasets and model outputs.

Changes

Files Change Summary
dreem/datasets/sleap_dataset.py Refactored video handling from a list to a dictionary for video readers, improved error handling in get_instances, and updated destructor for proper resource management.
dreem/inference/eval.py Modified configuration handling in run function to support batch processing with CSV input, improved user prompts for pod index, and retained checkpoint loading conditionally.
dreem/inference/track.py Updated run function to replace checkpoint loading with batch configuration handling, enhanced error prompts, and refined logging for hyperparameters.
dreem/io/config.py Enhanced get_dataset and get_dataloader methods to return None for empty datasets, added logging for warnings, and implemented consistent file sorting for labels and videos.
dreem/models/embedding.py Added normalization for the times tensor in the _learned_temp_embedding method, ensuring consistent input scaling.
dreem/models/gtr_runner.py Simplified video name extraction and updated ground truth track ID handling by using list comprehension instead of tensor methods, improving code clarity.

🐰 In the meadow where I hop and play,
New changes come to brighten the day!
With videos neat and datasets bright,
Batch processing makes everything right!
So let’s dance and twirl in delight,
For clearer paths and data in sight! 🌼✨

Tips ### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `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 generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@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. ### CodeRabbit Commands (Invoked using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` anywhere in the PR title to generate the title automatically. ### CodeRabbit Configuration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
