👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

Code Review

This pull request comments out the logic for handling eplb_config, which is critical for expert parallelism load balancing. The title "[Test] test remove this code after ci" strongly suggests this is a temporary change for testing and should not be merged in its current state. If this functionality is intended to be removed, the code should be deleted rather than commented out. Otherwise, it must be restored before merging.

This change comments out the logic for processing eplb_config. Based on the pull request title, this appears to be a temporary change for testing purposes. Merging this as-is would break the expert parallelism load balancing configuration. This code should be restored before merging.

Suggested change

	# if isinstance(self.eplb_config, dict):
	# self.eplb_config = EPLBConfig.from_cli(json.dumps(
	# self.eplb_config))
	if isinstance(self.eplb_config, dict):
	self.eplb_config = EPLBConfig.from_cli(json.dumps(
	self.eplb_config))
