Pull Request Overview

This PR introduces example configuration and documentation updates for the evaluation framework, modernizes dependency management, and consolidates memory backend handling by removing legacy code.

• Added new dependencies to pyproject.toml for evaluation configs, environment loading, and model support.
• Refactored the get_client and search/response scripts to unify the memos backend (removing memos_mos) and added a top_k parameter.
• Updated CLI choices across scripts and streamlined the README to reference a .env-example and configs-example directory.

Comments suppressed due to low confidence (4)

evaluation/scripts/locomo/locomo_ingestion.py:126

• The ingest_session function no longer includes a branch to handle the memos frame, so data will not be ingested for that backend. Restoring or adding appropriate ingestion logic for memos is needed.

            )

evaluation/scripts/locomo/locomo_search.py:445

• The help string for the --lib flag lists frameworks but omits langmem (and optionally openai), leading to a mismatch with the choices list. Please update the help text to reflect the actual available options.

        help="Specify the memory framework (zep or memos or mem0 or mem0_graph)",

evaluation/README.md:27

• [nitpick] The instructions now refer to run_locomo_eval.sh but don't explain where to find or how to configure it, nor the steps for ingestion and search. Consider elaborating the evaluation workflow or including the script contents for clarity.

pyproject.toml:54

• [nitpick] Added dependency lines appear to lack the same indentation as existing entries in the [tool.poetry.dependencies] section, which may affect readability or formatting. Consider aligning them with the existing entries.

scipy = "^1.10.1"

This dependency (pydantic) can be removed since it is implicitly required by other dependencies and does not need to be explicitly specified. After deleting this line, run poetry lock to update the poetry.lock.

---

该依赖项（pydantic）可以被移除，因为它已被其他依赖项隐式引入，无需显式指定。删除此行后，请运行 poetry lock 以更新 poetry.lock。

@Ki-Seki I have solved the two problems.
