+
+    Objects like ResNet18_Weights are enums with fields, where each field is a Weight object.
+    Enums aren't easily documented in Python so the solution we're going for is to:
+
+    - add an autoclass directive in the model's builder docstring, e.g.
+
+    ```
+    .. autoclass:: torchvision.models.ResNet34_Weights
+        :members:
+    ```
+
+    (see resnet.py for an example)
+    - then this hook is called automatically when building the docs, and it generates the text that gets
+      used within the autoclass directive.
