model-downloader-util
Download model files from local paths, HTTP(S), S3 / MinIO / RustFS, GCS, or Git LFS.
Install
pip install modeldownloaderutil
Usage
from modeldownloaderutil import download_model, resolve_model, sources
path = download_model("s3://bucket/models/weights.onnx")
path = download_model("https://example.com/model.onnx")
path = download_model("git+https://github.com/org/repo.git#weights/a.onnx")
# Try sources in order (first success wins):
path = download_model(sources(
"rustfs://bucket/org/repo/weights/a.onnx",
"git+https://github.com/org/repo.git#weights/a.onnx",
))
# same as:
path = download_model(
"rustfs://bucket/org/repo/weights/a.onnx,git+https://github.com/org/repo.git#weights/a.onnx"
)
# Unpack zip archives and locate the weights file (.onnx, .pt, …):
path = resolve_model("s3://bucket/models/weights.onnx.zip")
