Walkthrough

The pull request introduces several significant changes across multiple scripts related to machine learning model benchmarking and image generation. A new benchmarking script, run_benchmark.sh, has been added to facilitate the testing of various models, including Stable Diffusion and FLUX. Enhancements have been made to text_to_image.py files, incorporating quantization capabilities and improved argument parsing. New functionalities, such as a command-line interface for image generation in text_to_image_flux.py and text_to_image_sd3.py, have also been implemented to allow for more customizable model configurations. Additionally, a new README.md file has been created to guide users in setting up and executing the Flux model.

Changes

File	Change Summary
benchmarks/run_benchmark.sh	New script added to benchmark machine learning models with environment setup, command-line argument handling, and logging.
benchmarks/text_to_image.py	Added quantization capabilities; modified the main function for improved control flow and error handling.
onediff_diffusers_extensions/examples/flux/text_to_image_flux.py	New file with command-line interface for image generation, including model loading and performance tracking.
onediff_diffusers_extensions/examples/sd3/text_to_image_sd3.py	Significant modifications for argument parsing and structure; introduced new constants and functions for modularity.
onediff_diffusers_extensions/examples/flux/README.md	New documentation file added to guide setup and execution of the Flux model with performance benchmarks.

Possibly related PRs

• [#1094] The changes in the README.md file may indirectly relate to the benchmarking process by providing context or instructions for users on how to utilize the models being benchmarked, although it does not directly modify any benchmarking functionality.

Poem

🐇 In the meadow, bright and fair,
New scripts hop with joyful flair.
Models run and metrics shine,
With every test, the results align.
So let us cheer, both loud and clear,
For changes that bring us closer, dear! 🌼

🪧 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 , 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. ### 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](http://discord.gg/coderabbit) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
