+MNASNet
+=======
+
+.. currentmodule:: torchvision.models
+
+
+The MNASNet model is based on the `MnasNet: Platform-Aware Neural Architecture
+Search for Mobile <https://arxiv.org/pdf/1807.11626.pdf>`__ paper.
+
+
+Model builders
+--------------
+
+The following model builders can be used to instanciate an MNASNet model, with or
+without pre-trained weights. All the model builders internally rely on the
+``torchvision.models.mnasnet.MNASNet`` base class. Please refer to the `source
+code
+<https://github.com/pytorch/vision/blob/main/torchvision/models/mnasnet.py>`_ for
+more details about this class.
