-# HuggingFace ONNX
-
-Tool for discovering, downloading, and validating ONNX models from HuggingFace.
-
-## Extra Dependencies
-
-```bash
-pip install huggingface_hub pyyaml requests onnx onnxruntime numpy
-```
-
-## Huggingface Manager (discovering and downloading)
-
-The `huggingface_manager.py` script discovers top ONNX models from HuggingFace, collects metadata, and optionally downloads them.
-
-```bash
-# Download top 50 models sorted by downloads
-python huggingface_manager.py --limit 50 --download
-
-# Just collect metadata (no download)
-python huggingface_manager.py --limit 100
-
-# Sort by likes instead of downloads
-python huggingface_manager.py --limit 20 --sort likes --download
-
-# Custom output file
-python huggingface_manager.py --limit 10 --output my_models.yaml
-```
-
-### Output Format
-
-The tool generates a YAML file with the following structure:
-
-```yaml
-repositories:
-  "model-name":
-    url: "https://huggingface.co/model-name"
-    download_path: "/path/to/models/..."  # when --download used
-    files:
-      - file: "model.onnx"
-        size: "90.91MB"
-total_size: "2.45GB"
-created_at: "2024-01-15T10:30:00Z"
-```
-
-## Run Models (validation)
-
-The `run_models.py` script validates ONNX models against ONNX Runtime for correctness.
-
-```bash
-# Validate models from a YAML configuration file
-python run_models.py --validate huggingface_repos.yaml
-
-# Debug specific repository (downloads and validates all ONNX models)
-python run_models.py --debug sentence-transformers/all-MiniLM-L6-v2
-
-# Debug specific model file
-python run_models.py --debug sentence-transformers/all-MiniLM-L6-v2/onnx/model.onnx
-
-# Debug with model truncation for debugging and validating intermediate results
-DEBUGONNX=1 python run_models.py --debug sentence-transformers/all-MiniLM-L6-v2/onnx/model.onnx --truncate 10
