  SparseZoo

Neural network model repository for highly sparse and sparse-quantized models with matching sparsification recipes

Overview

SparseZoo is a constantly-growing repository of sparsified (pruned and pruned-quantized) models with matching sparsification recipes for neural networks. It simplifies and accelerates your time-to-value in building performant deep learning models with a collection of inference-optimized models and recipes to prototype from. Read more about sparsification here.

Available via API and hosted in the cloud, the SparseZoo contains both baseline and models sparsified to different degrees of inference performance vs. baseline loss recovery. Recipe-driven approaches built around sparsification algorithms allow you to use the models as given, transfer-learn from the models onto private datasets, or transfer the recipes to your architectures.

The GitHub repository contains the Python API code to handle the connection and authentication to the cloud.

Installation

This repository is tested on Python 3.6-3.9, and Linux/Debian systems. It is recommended to install in a virtual environment to keep your system in order.

Install with pip using:

pip install sparsezoo

Quick Tour

Python APIs

The Python APIs respect this format enabling you to search and download models. Some code examples are given below. The SparseZoo UI also enables users to load models by copying a stub directly from a model page.

Loading from a Stub

from sparsezoo import Model

# copied from https://sparsezoo.neuralmagic.com/
stub = "zoo:cv/classification/resnet_v1-50/pytorch/sparseml/imagenet/pruned90_quant-none"
model = Model(stub)
print(model)

Searching the Zoo

from sparsezoo import search_models

models = search_models(
    domain="cv",
    sub_domain="classification",
    return_stubs=True,
)
print(models)

Environmental Variables

Users can specify the directory where models (temporarily during download) and its required credentials will be saved in your working machine. SPARSEZOO_MODELS_PATH is the path where the downloaded models will be saved temporarily. Default ~/.cache/sparsezoo/ SPARSEZOO_CREDENTIALS_PATH is the path where credentials.yaml will be saved. Default ~/.cache/sparsezoo/

Console Scripts

In addition to the Python APIs, a console script entry point is installed with the package sparsezoo. This enables easy interaction straight from your console/terminal.
