"""The models subpackage contains definitions for the following model
architectures:

-  `AlexNet`_
-  `VGG`_
-  `ResNet`_
-  `SqueezeNet`_
-  `DenseNet`_

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

.. code:: python

    import torchvision.models as models
    resnet18 = models.resnet18()
    alexnet = models.alexnet()
    squeezenet = models.squeezenet1_0()
    densenet = models.densenet_161()

We provide pre-trained models for the ResNet variants and AlexNet, using the
PyTorch :mod:`torch.utils.model_zoo`. These can  constructed by passing
``pretrained=True``:

.. code:: python

    import torchvision.models as models
    resnet18 = models.resnet18(pretrained=True)
    alexnet = models.alexnet(pretrained=True)
