GLM-OCR to CoreML conversion

Notebooks and assets to convert GLM-OCR to CoreML for iOS/macOS.

Contents

• glm_ocr_coreml_v4.ipynb – Main conversion notebook (vision encoder + optional decoder, quantization, accuracy check). Use this.
• glm_ocr_coreml.ipynb – Older notebook variant.
• glm_ocr_coreml_requirements.txt – Python dependencies (Python 3.10+ recommended; transformers main branch required for GLM-OCR).

Requirements

• Python 3.10+
• PyTorch, transformers (from main), coremltools 7.2+

Quick start

1. Create a venv with Python 3.10+ and install:

   pip install -r glm_ocr_coreml_requirements.txt
   pip install "git+https://github.com/huggingface/transformers.git@main"
   

2. Open glm_ocr_coreml_v4.ipynb and run cells top to bottom.
3. Outputs go to glm_ocr_coreml/ (vision_encoder.mlpackage, model_spec.json, etc.).

Note

• .venv_glm_ocr is not included; create your own venv with Python 3.10+.
• Converted .mlpackage files can be uploaded separately if needed (they are large).
