Summary of Changes

Hello @slin000111, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements a minor bug fix related to the command-line display for the UI by refactoring a variable name. The change specifically renames a local variable involved in parsing environment variables, enhancing code readability and preventing potential conflicts with the original variable name, ultimately contributing to cleaner and more maintainable code.

Highlights

• Variable Renaming: The envs variable, used for processing environment variables, has been renamed to env_list within the train function in llm_train.py. This change improves code clarity and prevents potential variable shadowing.

Code Review

This pull request correctly fixes a bug where the envs variable was being reassigned, which would cause a crash later in the code. I've added a suggestion to make the environment variable parsing logic more robust to prevent other potential crashes, for instance, when there are multiple spaces between variables or when variable values contain an equals sign.

[gemini-code-assist]

While this change correctly avoids shadowing the envs variable, the environment variable parsing logic can be made more robust. The current implementation has two potential issues:

1. If there are multiple spaces between environment variable definitions (e.g., A=1 B=2), split(' ') will produce empty strings, causing a ValueError when unpacking.
2. If an environment variable's value contains an = sign (e.g., URL=http://a.com?x=y), split('=') will produce more than two values, also causing a ValueError.

I suggest a more robust implementation that also simplifies the code by removing the intermediate env_list.

Suggested change

	env_list = envs.split(' ')
	for env in env_list:
	k, v = env.split('=')
	all_envs[k] = v
	for env in envs.split(' '):
	if env and '=' in env:
	k, v = env.split('=', 1)
	all_envs[k] = v
