Where to find list of Tensorflow pretrained models available in download.tensorflow.org/models
It seems the models hosted on this are not listed anywhere publically (or at least my research failed!). However, there are official and several nonofficial GitHub repositories with high-level TensorFlow model definitions and pretrained weights. For example:

Nonofficial: that includes NASNet, ResNeXt, ResNet, InceptionV4, InceptionResnetV2, Xception, DPN (need PyTorch).
Official: contains a wide range of official and research models such as resnet, wide-deep, inception, delf, and tcn.

Hope it helps.
