Physical Environment

Our project is a physical environment to train LLMs to generate STL files, the same files used in physical CAD designs.

Setup

$ pip install pyrender trimesh pyglet matplotlib torch transformers pydantic vllm numpy requests tenacity wandb

Shared libraries for Ubuntu GL rendering.

$ sudo apt-get install libglfw3-dev libgles2-mesa-dev libnvidia-gl-570-server

Training Data Generation

• Use dataset_scr.py to create the following directory structure:

  dataset/
  ├── stls/
  │   ├── model_0001.stl
  │   ├── model_0002.stl
  │   └── ...
  ├── images/
  │   ├── model_0001.png
  │   ├── model_0002.png
  │   └── ...
  └── labels.json
  

• Use render_stl.py to generate images from STL files.
• Use llm_label.py to label the STL and image files.
• Use prepare_push_hf_dataset.py to push the dataset to Hugging Face.
