HF Jobs Utilities

Small utility scripts for working with the uv-scripts collection and Hugging Face Jobs — discovering the available recipes, and testing/benchmarking your Jobs setup.

Available Scripts

list-recipes.py

List every recipe (UV script) across the whole uv-scripts org, with a runnable URL for each. The zero-setup way to see what's available — no GPU, no token, no account; it only reads public repos.

Run locally (nothing to install but uv):

uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/list-recipes.py

Add --describe to also print the first line of each script's docstring (slower — it fetches each file):

uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/list-recipes.py --describe

Each printed URL runs the same way: uv run <url> locally, or hf jobs uv run <url> on a GPU.

network-speed-test.py

Test network download speed from within an HF Jobs environment. Useful for:

• Verifying network connectivity
• Comparing download speeds across different GPU flavors
• Benchmarking before running large dataset downloads
• Troubleshooting slow data loading issues

Features:

• Pure Python (no dependencies required)
• Fast default test with small file
• Optional --large flag for realistic ~100MB test
• Clear metrics (MB/s and Mbps)
• Works locally or on HF Jobs

Usage

Run locally:

# Quick test with small file
uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py

# More realistic test with ~100MB file
uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large

# Custom URL
uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py \
    --url https://example.com/testfile.bin

Run on HF Jobs:

# Test network speed on L4 GPU
hfjobs run --flavor l4x1 \
    -s HF_TOKEN \
    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large

# Compare across different flavors
hfjobs run --flavor a10 \
    -s HF_TOKEN \
    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large

hfjobs run --flavor h100 \
    -s HF_TOKEN \
    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large

Why These Utilities?

HF Jobs provides different GPU flavors with varying network configurations. These utilities help you:

1. Make informed decisions - Compare network speeds before choosing a flavor
2. Debug issues - Verify network connectivity when data loading is slow
3. Optimize workflows - Understand if network speed is a bottleneck
4. Benchmark environments - Document baseline performance for your use case

About UV Scripts

This is part of the uv-scripts collection - ready-to-run Python scripts that work with a single uv run command. No setup, no virtual environments, just instant execution.
