Graph-Break Type

Short name describing what triggered the graph break

Unsupported nn.Module attribute type

Values or code snippet captured at the break point

nn.Module subclass: {typestr(base)}, name: {name}, attribute type: {typestr(subobj)}

Explanation of why the graph break was triggered

Dynamo does not support tracing nn.Module attributes of type {typestr(subobj)}

Hints on how to resolve the graph break

Refactor your code so that {name} (type {typestr(subobj)}) is not an attribute of {typestr(base)}
Currently supported attribute types are methods, classmethods, staticmethods,
properties, constants, and tensors.
It may be possible to write Dynamo tracing rules for this code. Please report an issue to PyTorch if you encounter this graph break often and it is causing performance issues.
