Gluon Model Zoo¶

Overview¶

This document lists the model APIs in Gluon:

`mxnet.gluon.model_zoo`	Predefined and pretrained models.
`mxnet.gluon.model_zoo.vision`	Module for pre-defined neural network models.

The Gluon Model Zoo API, defined in the gluon.model_zoo package, provides pre-defined and pre-trained models to help bootstrap machine learning applications.

In the rest of this document, we list routines provided by the gluon.model_zoo package.

Vision¶

Module for pre-defined neural network models.

This module contains definitions for the following model architectures: - AlexNet - DenseNet - Inception V3 - ResNet V1 - ResNet V2 - SqueezeNet - VGG - MobileNet

You can construct a model with random weights by calling its constructor:

from mxnet.gluon.model_zoo import vision
resnet18 = vision.resnet18_v1()
alexnet = vision.alexnet()
squeezenet = vision.squeezenet1_0()
densenet = vision.densenet_161()

We provide pre-trained models for all the models except ResNet V2. These can constructed by passing pretrained=True:

from mxnet.gluon.model_zoo import vision
resnet18 = vision.resnet18_v1(pretrained=True)
alexnet = vision.alexnet(pretrained=True)

Pretrained models are converted from torchvision. All pre-trained models expect input images normalized in the same way, i.e. mini-batches of 3-channel RGB images of shape (N x 3 x H x W), where N is the batch size, and H and W are expected to be at least 224. The images have to be loaded in to a range of [0, 1] and then normalized using mean = [0.485, 0.456, 0.406] and std = [0.229, 0.224, 0.225]. The transformation should preferrably happen at preprocessing. You can use mx.image.color_normalize for such transformation:

image = image/255
normalized = mx.image.color_normalize(image,
                                      mean=mx.nd.array([0.485, 0.456, 0.406]),
                                      std=mx.nd.array([0.229, 0.224, 0.225]))

Parameters:	pretrained (bool, default False) – Whether to load the pretrained weights for model. ctx (Context, default CPU) – The context in which to load the pretrained weights. root (str, default '~/.mxnet/models') – Location for keeping the model parameters.

mxnet.gluon.model_zoo.vision.vgg19_bn(**kwargs)[source]¶

VGG-19 model with batch normalization from the “Very Deep Convolutional Networks for Large-Scale Image Recognition” paper.

Parameters:	pretrained (bool, default False) – Whether to load the pretrained weights for model. ctx (Context, default CPU) – The context in which to load the pretrained weights. root (str, default '~/.mxnet/models') – Location for keeping the model parameters.
