flowvision

Introduction

The flowvision package consists of popular datasets, SOTA computer vision models, layers, utilities, schedulers, advanced data augmentations and common image transformations based on OneFlow.

Installation

First install OneFlow, please refer to install-oneflow for more details.

Then install the latest stable release of flowvision

pip install flowvision==0.2.2

Quick Start

Create a model

In flowvision we support two ways to create a model.

• Import the target model from flowvision.models, e.g., create alexnet from flowvision

from flowvision.models.alexnet import alexnet
model = alexnet()

# will download the pretrained model
model = alexnet(pretrained=True)

# customize model to fit different number of classes
model = alexnet(num_classes=100)

• Or create model in an easier way by using ModelCreator, e.g., create alexnet model by ModelCreator

from flowvision.models import ModelCreator
alexnet = ModelCreator.create_model("alexnet")

# will download the pretrained model
alexnet = ModelCreator.create_model("alexnet", pretrained=True)

# customize model to fit different number of classes
alexnet = ModelCreator.create_model("alexnet", num_classes=100)

Tabulate all models with pretrained weights

ModelCreator.model_table() returns a tabular results of available models in flowvision. To check all of pretrained models, pass in pretrained=True in ModelCreator.model_table().

from flowvision.models import ModelCreator
all_pretrained_models = ModelCreator.model_table(pretrained=True)
print(all_pretrained_models)

You can get the results like:

Search for supported model by Wildcard

It is easy to search for model architectures by using Wildcard as below:

from flowvision.models import ModelCreator
all_efficientnet_models = ModelCreator.model_table("**efficientnet**")
print(all_efficientnet_models)

You can get the results like:

╒════════════════════╤══════════════╕
│ Supported Models   │ Pretrained   │
╞════════════════════╪══════════════╡
│ efficientnet_b0    │ true         │

List all models supported in flowvision

ModelCreator.model_list has similar function as ModelCreator.model_table but return a list object, which gives the user a more flexible way to check the supported model in flowvision.

• List all models with pretrained weights

from flowvision.models import ModelCreator
all_pretrained_models = ModelCreator.model_list(pretrained=True)
print(all_pretrained_models[:5])

You can get the results like:

['alexnet', 
 'convmixer_1024_20', 
 'convmixer_1536_20', 
 'convmixer_768_32_relu', 
 'crossformer_base_patch4_group7_224']

• Support wildcard search

from flowvision.models import ModelCreator
all_efficientnet_models = ModelCreator.model_list("**efficientnet**")
print(all_efficientnet_models)

You can get the results like:

['efficientnet_b0', 
 'efficientnet_b1', 
 'efficientnet_b2', 
 'efficientnet_b3', 
 'efficientnet_b4', 
 'efficientnet_b5', 
 'efficientnet_b6', 
 'efficientnet_b7']
