The infrastructure of the framework is based on OSWorld together with VMware Workstation Pro (which is free for personal use since May, 2024) in Ubuntu or Windows. Please make sure that your device meets the minimal requirements of these preliminaries.

1. Download VMware Workstation Pro 17 and our pre-made images from Hugging Face;

2. Clone this repository and install packages needed:

   git clone https://github.com/OS-Copilot/ScienceBoard
   cd ScienceBoard
   conda create -n sci python=3.11
   conda activate sci
   pip install -r requirements.txt

3. We recommend you to change evaluating process in main.py directly with some sensitive information hidden in environment variables, especially when it comes to complicate configs concerning community.

1. Used in our template of main.py:

   • VM_PATH: path to vmware .vmx file; will be automatically extracted (repeatedly) if set to path of VM.zip
   • HTTPX_PROXY: proxy URL if needed; avoid clashes with HTTP_PROXY and HTTPS_PROXY on Linux;
   • OPENAI_API_KEY: API key for OpenAI GPT;
   • GOOGLE_API_KEY: API key for Google Gemini;
   • ANTHROPIC_API_KEY: API key for Anthropic Claude;

   and variables for open-source models:

   Model	Base URL	Name
   QwenVL	QWEN_VL_URL	QWEN_VL_NAME
   InternVL	INTERN_VL_URL	INTERN_VL_NAME
   QVQ	QVQ_VL_URL	QVQ_VL_NAME
   OS-Atlas	OS_ACT_URL	OS_ACT_NAME
   GUI-Actor	GUI_ACTOR_URL	GUI_ACTOR_NAME
   UI-Tars	TARS_DPO_URL	TARS_DPO_NAME

2. Used in sci/Presets.py:

   • LEAN_LIB_PATH: path for Lean 4 REPL;
   • QT6_LIB_PATH: dynamic library directory for Qt6;
   • FFI_LIB_PATH: dynamic library file for libffi.so;
   • KALG_BIN_PATH: executable binary file of KAlgebra;
   • CELE_BIN_PATH: executable binary file of Celestia;
   • GIS_BIN_PATH: executable binary file of Grass GIS.

• DEBUG_ERR_FACT: insert a breakpoint when eval exception occur if set to any value;

1. Automata: a simple encapsulation for Model and Agent
   • model_style: affect the request format and response processing of model calling; you can customize your own style by adding _request_{style}() and _access_{style}() under Model;
   • overflow_style: affect the way we detect overflow of token; you can customize your own style by adding {style}() under Overflow;
   • code_style: affect the way we process code blocks when communicating with models; you can customize your own style by adding wrap_{style}() and extract_{style}() under CodeLike.
2. Tester: __init__() only register a new config. use __call__() for actual evaluation after init.
   • tasks_path: the directory or file path for json file(s) of task(s); all *.json files under the path specified will be recursively loaded when a directory path is provided;
   • logs_path: the directory path for log files and will be created automatically when not existed; the structure of the directory will be arranged according to that under tasks_path;
   • community: the way of cooperation among multiple agents; use AllInOne for standard setting inherited from OSWorld;
   • ignore: skipped when log indicates that the task is finished (by checking the existence of result.out) if set to True; so you can re-run the same program to retry failure cases only;
   • debug: finish the tasks manually instead of calling models;
   • relative: allow VM to execute pyautogui codes with relative coordinates; basically used by InternVL-3.

1. Error when initializing:

   Traceback (most recent call last):
       File "/usr/lib/python3.11/site-packages/requests/models.py", line 971, in json
           return complexjson.loads(self.text, **kwargs)

       json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

   the target app has not yet been started up when trying to initialize due to insufficient performance of your device; try to assign a bigger value for 'wait' field in json files of the tasks.

   fail to authenticate in newly downloaded images; input password once manually in VMWare and take a new snapshot using the same name as before and delete the former one.

If you are willing to add new applications into ScienceBoard, please make sure that you already have a full understanding of your target application and this repository.

1. Write a plugin or implant a server in your target application revealing its inner states. Listed below is repositories of our modified applications:
   • chimerax-states: a plugin for ChimeraX;
   • kalgebra: a recompilation copy of KAlgebra;
   • Celestia: a recompilation copy of Celestia;
   • grass-gis: GUI part in Python of Grass GIS.
2. Copy sci/Template and rename it to the name of your target application;
   • template.py: direct managers for the Raw / VM application;
   • task.py: initialization and evaluation of tasks using RESTful API with your server;
   • __init__.py: change the name of template.py.
3. Write json files of tasks and modified VM images.

See Staff Manual of VM Image.

It is recommended to run this project with at least the following configuration:
