+EfficientNetV2
+============
+
+.. currentmodule:: torchvision.models
+
+The EfficientNetV2 model is based on the `EfficientNetV2: Smaller Models and Faster Training <https://arxiv.org/abs/2104.00298>`__
+paper.
+
+
+Model builders
+--------------
+
+The following model builders can be used to instanciate an EfficientNetV2 model, with or
+without pre-trained weights. All the model builders internally rely on the
+``torchvision.models.efficientnet.EfficientNet`` base class. Please refer to the `source
+code
+<https://github.com/pytorch/vision/blob/main/torchvision/models/efficientnet.py>`_ for
+more details about this class.
