I see various places on the web and even in code from a homework assignment that just seems to know where pretrained checkpoints for various tf-slim models can be downloaded.

Example: http://download.tensorflow.org/models/inception_resnet_v2_2016_08_30.tar.gz

But if you visit download.tensorflow.org, there is no page returned so that you can pick and choose or just know the fully qualified URL to download the checkpoint files.

So if you don't know the name of the file (or what architecture you want to use), then how can you find these pretrained weight checkpoint files?

You have to start your browsing from the tensorflow/models repository. When you open it, scroll down, and you see the README.md. It has links to the four model categories: official, research, smaples, tutorials.

Let's examine the official. It has three nets there, mnist, resnet, and wide_deep. Click on resnet, scroll down to the Pre-trained model section, and you will find links there to the pre-trained models. Note: not all models have pre-trained weights.
