Project description
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.
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.

Quick Tour
The SparseZoo Python API enables you to search and download sparsified models. Code examples are given below. We encourage users to load SparseZoo models by copying a stub directly from a model page.
Introduction to Model Class Object
The Model
is a fundamental object that serves as a main interface with the SparseZoo library.
It represents a SparseZoo model, together with all its directories and files.
Creating a Model Class Object From SparseZoo Stub
from sparsezoo import Model
stub = "zoo:cv/classification/resnet_v1-50/pytorch/sparseml/imagenet/pruned95_quant-none"
model = Model(stub)
print(str(model))
>> Model(stub=zoo:cv/classification/resnet_v1-50/pytorch/sparseml/imagenet/pruned95_quant-none)
Creating a Model Class Object From Local Model Directory
from sparsezoo import Model
directory = ".../.cache/sparsezoo/eb977dae-2454-471b-9870-4cf38074acf0"
model = Model(directory)
print(str(model))
>> Model(directory=.../.cache/sparsezoo/eb977dae-2454-471b-9870-4cf38074acf0)
Manually Specifying the Model Download Path
Unless specified otherwise, the model created from the SparseZoo stub is saved to the local sparsezoo cache directory.
This can be overridden by passing the optional download_path
argument to the constructor:
from sparsezoo import Model
stub = "zoo:cv/classification/resnet_v1-50/pytorch/sparseml/imagenet/pruned95_quant-none"
download_directory = "./model_download_directory"
model = Model(stub, download_path = download_directory)
Downloading the Model Files
Once the model is initialized from a stub, it may be downloaded either by calling the download()
method or by invoking a path
property. Both pathways are universal for all the files in SparseZoo. Invoking the path
property will always trigger file download unless the file has already been downloaded.
# method 1
model.download()
# method 2
model_path = model.path
Inspecting the Contents of the SparseZoo Model
We call the available_files
method to inspect which files are present in the SparseZoo model. Then, we select a file by calling the appropriate attribute:
model.available_files
>> {'training': Directory(name=training),
>> 'deployment': Directory(name=deployment),
>> 'sample_inputs': Directory(name=sample_inputs.tar.gz),
>> 'sample_outputs': {'framework': Directory(name=sample_outputs.tar.gz)},
>> 'sample_labels': Directory(name=sample_labels.tar.gz),
>> 'model_card': File(name=model.md),
>> 'recipes': Directory(name=recipe),
>> 'onnx_model': File(name=model.onnx)}
Then, we might take a closer look at the contents of the SparseZoo model:
model_card = model.model_card
print(model_card)
>> File(name=model.md)
model_card_path = model.model_card.path
print(model_card_path)
>> .../.cache/sparsezoo/eb977dae-2454-471b-9870-4cf38074acf0/model.md
Model, Directory, and File
In general, every file in the SparseZoo model shares a set of attributes: name
, path
, URL
, and parent
:
name
serves as an identifier of the file/directorypath
points to the location of the file/directoryURL
specifies the server address of the file/directory in questionparent
points to the location of the parent directory of the file/directory in question
A directory is a unique type of file that contains other files. For that reason, it has an additional files
attribute.
print(model.onnx_model)
>> File(name=model.onnx)
print(f"File name: {model.onnx_model.name}\n"
f"File path: {model.onnx_model.path}\n"
f"File URL: {model.onnx_model.url}\n"
f"Parent directory: {model.onnx_model.parent_directory}")
>> File name: model.onnx
>> File path: .../.cache/sparsezoo/eb977dae-2454-471b-9870-4cf38074acf0/model.onnx
>> File URL: https://models.neuralmagic.com/cv-classification/...
>> Parent directory: .../.cache/sparsezoo/eb977dae-2454-471b-9870-4cf38074acf0
print(model.recipes)
>> Directory(name=recipe)
print(f"File name: {model.recipes.name}\n"
f"Contains: {[file.name for file in model.recipes.files]}\n"
f"File path: {model.recipes.path}\n"
f"File URL: {model.recipes.url}\n"
f"Parent directory: {model.recipes.parent_directory}")
>> File name: recipe
>> Contains: ['recipe_original.md', 'recipe_transfer-classification.md']
>> File path: /home/user/.cache/sparsezoo/eb977dae-2454-471b-9870-4cf38074acf0/recipe
>> File URL: None
>> Parent directory: /home/user/.cache/sparsezoo/eb977dae-2454-471b-9870-4cf38074acf0
Selecting Checkpoint-Specific Data
A SparseZoo model may contain several checkpoints. The model may contain a checkpoint that had been saved before the model was quantized - that checkpoint would be used for transfer learning. Another checkpoint might have been saved after the quantization step - that one is usually directly used for inference.
The recipes may also vary depending on the use case. We may want to access a recipe that was used to sparsify the dense model (recipe_original
) or the one that enables us to sparse transfer learn from the already sparsified model (recipe_transfer
).
There are two ways to access those specific files.
Accessing Recipes (Through Python API)
available_recipes = model.recipes.available
print(available_recipes)
>> ['original', 'transfer-classification']
transfer_recipe = model.recipes["transfer-classification"]
print(transfer_recipe)
>> File(name=recipe_transfer-classification.md)
original_recipe = model.recipes.default # recipe defaults to `original`
original_recipe_path = original_recipe.path # downloads the recipe and returns its path
print(original_recipe_path)
>> .../.cache/sparsezoo/eb977dae-2454-471b-9870-4cf38074acf0/recipe/recipe_original.md
Accessing Checkpoints (Through Python API)
In general, we are expecting the following checkpoints to be included in the model:
checkpoint_prepruning
checkpoint_postpruning
checkpoint_preqat
checkpoint_postqat
The checkpoint that the model defaults to is the preqat
state (just before the quantization step).
from sparsezoo import Model
stub = "zoo:nlp/question_answering/bert-base/pytorch/huggingface/squad/pruned_quant_3layers-aggressive_84"
model = Model(stub)
available_checkpoints = model.training.available
print(available_checkpoints)
>> ['preqat']
preqat_checkpoint = model.training.default # recipe defaults to `preqat`
preqat_checkpoint_path = preqat_checkpoint.path # downloads the checkpoint and returns its path
print(preqat_checkpoint_path)
>> .../.cache/sparsezoo/0857c6f2-13c1-43c9-8db8-8f89a548dccd/training
[print(file.name) for file in preqat_checkpoint.files]
>> vocab.txt
>> special_tokens_map.json
>> pytorch_model.bin
>> config.json
>> training_args.bin
>> tokenizer_config.json
>> trainer_state.json
>> tokenizer.json
Accessing Recipes (Through Stub String Arguments)
You can also directly request a specific recipe/checkpoint type by appending the appropriate URL query arguments to the stub:
from sparsezoo import Model
stub = "zoo:cv/classification/resnet_v1-50/pytorch/sparseml/imagenet/pruned95_quant-none?recipe=transfer"
model = Model(stub)
# Inspect which files are present.
# Note that the available recipes are restricted
# according to the specified URL query arguments
print(model.recipes.available)
>> ['transfer-classification']
transfer_recipe = model.recipes.default # Now the recipes default to the one selected by the stub string arguments
print(transfer_recipe)
>> File(name=recipe_transfer-classification.md)
Accessing Sample Data
The user may easily request a sample batch of data that represents the inputs and outputs of the model.
sample_data = model.sample_batch(batch_size = 10)
print(sample_data['sample_inputs'][0].shape)
>> (10, 3, 224, 224) # (batch_size, num_channels, image_dim, image_dim)
print(sample_data['sample_outputs'][0].shape)
>> (10, 1000) # (batch_size, num_classes)
Model Search
The function search_models
enables the user to quickly filter the contents of SparseZoo repository to find the stubs of interest:
from sparsezoo import search_models
args = {
"domain": "cv",
"sub_domain": "segmentation",
"architecture": "yolact",
}
models = search_models(**args)
[print(model) for model in models]
>> Model(stub=zoo:cv/segmentation/yolact-darknet53/pytorch/dbolya/coco/pruned82_quant-none)
>> Model(stub=zoo:cv/segmentation/yolact-darknet53/pytorch/dbolya/coco/pruned90-none)
>> Model(stub=zoo:cv/segmentation/yolact-darknet53/pytorch/dbolya/coco/base-none)
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.
